REL T7X Sub Review (+ REL's setup process)

[@andrewbardwell4832]

I just added the T5X to my Rega/ProAc set-up. I cannot believe the difference. I listen to a lot of jazz... the left hand on the piano and stand up bass have a weight and richness that were lacking. Really amazing.

[@abritishaudiophile7314]

That is great Andrew. Thank you for sharing 👍

Yep me too I need to buy a T/7X next

[@Djk0t]

Thank you for sharing. What size is the room? Did you also consider the t7x as well? If yes why did you go for the T5x? Are you considering to try 2 of them?

[@montycaps8235]

I never thought I would ever add a subwoofer to my system. I added a pair of T/5X’s to my current small system and I was completely blown away by the results. The depth ,width and over soundstage they added was game changing for me. Would never live without a Rel product now.

[@RGMDG]

@@bobb.9917 SO you think two is the way to go? I guess so since you bought them. I have an opportunity to buy a T/7x for a great price or pay a few hundred more and get two T/5x's. Quite the quandary.. 1st world problem clearly..

[@Artemis_Prix]

@@RGMDG Hi Robert, Rel has a number of videos to help individuals choose between buying a pair or only one. In one of the videos, their CEO stated very clearly that if budget is part of the conversation, you are always better off buying the more powerful model vs buying a pair of lower powered subs even if the pricing works out to be the same. I mention this because I faced the same quandary - buy two R/9x or one S/510. I followed this advice and bought the S/510. My word, I am so glad I did! The power and musicality that sub brings to the table is utterly epic. I will never have a need for more bass nor another sub and I'm a bass fanatic (I have a large room - 20x30 and I only have it set at about 30% power - my room literally throbs with bass and yes, you can feel it in your chest). I found my forever sub. Hope that helps.

[@RGMDG]

@@Artemis_Prix Thanks Stephen. I ended up with the T/7x and got ti dialed in. Wow, very impressive. I had it originally connected to some 3-Way ELAC UB52's but wanted to try my ProAC Tablette speakers. I prefer the Tablette's over the ELAC's hands down. Very happy. I just keep saying "WOW, this sounds so good". If budget allows I may add another T/7x some day.

I treated myself to an 8", 65W M&K sub way back in the mid nineties. I was then living in a brick-internal-walled semi, very well soft furnished, and it added tremendous depth and atmosphere to my set up. Over the years I've moved 3 times and everything else has changed, but the M&K sub now graces my very own music room alongside Q Acoustics system 20s. Using a remote mains switch with a button next to my listening chair I can compare music with or without the sub in play, and the difference is still remarkable. Without it, the sound is thin and lacking body; with it the sound takes on a completeness that is overwhelmingly satisfying. Okay, the sub is getting on for 30 years old and, as you intimated, can be improved upon, but I reckon it was £450 well spent!

[@abritishaudiophile7314]

Definitely money well spent. Thank you for sharing Ian 😊👍

[@pauljoyquilter359]

I have been using REL subwoofers for several decades, becoming a convert in the late 1990's. I previously hated subwoofers with a passion due to how they slowed the music and ruined the timing. That all changed when I heard a REL Q50. I currently use twin REL #31 subs with my main speakers which alternate between Proac K6 Sig and Magnepan MG20.7i. With each of these speakers they integrate seamlessly and not only improve the bass extension, but also (and more importantly to me) greatly extend the soundstage depth, width and height for a more spacious soundstage. This added space is accompanied by greater midrange details - a bonus that many REL owners experience and comment upon.

I also run a stereo pair of t5/x subs, before i had stereo T/Zero's and the difference between them is night and day. The T5's are hooked up to my livingroom system coupled with dynaudio speakers and the T/Zero's now serve their duty in the bedroom system coupled with a set of modified Kef X300A speakers (officialy these speakers don't have subwoofer outputs) and they sound even more phenomenal in that smaller bedroom. I'm quitte happy with all four of them and i would highly recommend Rel subwoofers to anyone that is looking for a quality sub.

[@RichardDurishin]

I purchased a sub in 2008 and, for the past couple of years, as my listening skills have evolved, have thought it slow, ponderous and boomy; better for movies than music. Thank you for confirming the evolution in subs and changing my thoughts of what could be accomplished with a more musical one.

Most good hi fi speaker manufacturers get it right but the draw backs are you can’t get the extra octave that you need for the full audio spectrum, this is where the Rels come in all they do is make subs and boy do they get it right , so why would you not treat your self to one 😊

[@georgekallinikos9602]

Thanks Tarun great review. I have a subwoofer that we built ourselves and it sounds good. One of the best things we did was to integrate the subwoofer into my stereo system. This how I set mine up. My sub has a left and right high input so I connected that via speaker wire from each speaker. Firstly my speakers are bi-amped, I disconnected the top so it left the bottom end drivers playing, we then balance the volume of the sub with the other speakers so the sub did not dominate. we then played different tracks to set the crossover point and made sure the sub was not boomy. Then connected back the top end of the speakers and fiddled a little with the volume and crossover of the sub. Wow what a difference, it has enhanced both the bottom end and the mid range has also improved.

Hey Taren (forgive me if I misspelled your name), I just wanted to let you know I really enjoy your content. It seem as though reviewing can be somewhat subjective in deferent ways and dependent on context. It must be a balancing act to be fair and objective while still giving your opinion on a product. Sometimes it feels like reviews can err on the side of not giving their own personal feedback too much. I love your rating system at the end. I want to know what a reviewers personal take is and not just the objective facts of the product. Also, you just seem like a really nice guy and how you make your content is gracious and accessable for "lesser" audiophiles. That is huge. I may never be in a position to purchase many of the products you review but I still feel welcome to come along for the ride and learn. Thanks for the great channel.

[@dwaynepiper3261]

Hi Tarun I love how you include your technical knowledge, which seems above many other channels to compliment your subjective opinions. You're the first reviewer I have come across that actually opens up the. amplifier in reviews with a decent analysis of how well the product was designed. During the beginning of my journey into audio, I researched many aspects including room acoustics, and experimented with different setup topologies. All though I have forgotten some things the 5ms first reflection threshold is something that has always stuck in my mind and you are one of the first channels I have come across to mention it. I prefer live recordings when done well and try to replicate that feeling of being there. As such I found I prefer to include a 1 subwoofer or more plus a discrete center channel and these are the reasons I think this is the best setup. Bass interacts with the room differently therefore it makes sense to me that a full-range speaker is restrictive as the optimal placement is not the same as for the other frequencies and a sub gives you this tuning flexability in placement. In the early days moving from mono recordings to stereo, many advocated for 3 channels over two as the best solution for both recording and reproduction. In fact, many early classical and other recordings were done with 3 microphones to 3 tracks. Two-channel was adopted as the standard only because it was an easier prospect financially for many consumers at that time. In the quest for my goal, I settled on a unique setup to include 3 front channels plus subwoofer(s) for lower frequencies with a caveat. I use 1 surround sound receiver to upmix from stereo to multiple discrete channels for my center speaker. I run a second receiver in stereo mode for the left and right speakers. So basically I am combining a stereo phantom center image with a discrete center image. I like the soundstage and imaging I get in this configuration with proper speaker positioning and calibration. I think this works because as you mentioned previously as you toe your speakers in you get a better center image but reduce the width of the soundstage. In such a configuration, you can have a good wide soundstage and center image. It just seems more holographic to me this way as the stereo imaging combines with a real discrete center. And then of course add additional channels for cinema which I do not prefer for music listening. Also, have you any experience or opinion on an amplifier with Triple Darlington architecture? Do you have a preference for a Bipolar amplifier over Mosfet? My concern with running the REL from speaker-level inputs would be you are amplifying again any noise introduced from the first amplification. My understanding however is we may be less sensitive to it at the lower frequencies.

I added a T7X to my SF Lumina III, and it made a huge difference for me. I love my SF; however I felt them lacking in bass. The TX7 (1 unit) was seemless - I get the feeling the sound is coming from the SF. I must also mention - I find myself making adjustments to gain and the crossover from time to time. I would not hesitate in recommending the REL T7X. I love my sub and intend to keep it as long as Tarun has kept his REL :).

Ditto! Mine is still preforming well too 👍

[@johnsimpson8187]

I was recently at the stage of building my 2 channel system where it was time to add a subwoofer, and I chose the Dynaudio 18S. The reasons for this choice were that I wanted 2 channels of bass in a small footprint that could reach lower frequencies (16 Hz), at a reasonable price, and could work with my Hegel H90 Variable Line Outputs. I had tried the KEF KF92, but discovered a little talked about issue with the Hegel Line Outputs. The issue is that the power output from these outputs is VERY low. The Line Outputs did not provide enough power to drive the KEF. The Dynaudio 18S (and its cousin Sub 6) solves this Hegel Line Out problem by having an adjustable sensitivity for its Line Inputs. The adjustments are from +6 db (1 Vrms) to -14 db (10 Vrms). I set the sensitivity to +6 db and this works for me. I am also a fan of having adjustability of the input level from my DAC to the Amp. Having a DAC with a volume control (pre amp) allows for tuning the input volume from the DAC for best dynamic range for the Amp and perhaps other properties.

A few years ago I moved into a "post divorce apartment." It was a loft with the main room being 40'x20' with 16' high ceilings. My first purchase was a pair of Klipsch Forte 3 speakers. When connected to my 5 channel "high fi in a box" receiver it sounded bright and fatiguing. Next purchase was a cheap Reisong Boyuu A10 tube amplifier which made everything sweeter. My apartment was above a busy Mexican restaurant which meant that I could turn the volume up to 11 without any neighbor complaints. I quickly realized that I needed a sub-woofer. I got the REL T9, when it was being heavily discounted before the release of the newer models. The difference has been night and day. and not just in the ways that I imagined. Certainly, when I listen to New Order, BONES, Midnight Oil, or Aphex Twin, I can feel the floor rumbling through my feet. But more importantly, the whole sound feels richer, more complete and enveloping. I think that this purchase was probably the most impactful in increasing my enjoyment of music.

I have had a T/7x for nearly a year now and am completely in love with it, and my quake, it runs Hi level input from the centre speaker as suggested by the guys at REL.

My amplifier is manufactured by a long-time friend of mine in California and he also said a subwoofer is not necessary. After much deliberation, I ignored both and went ahead with purchasing the T/7X .. and boy am I glad. Once I got the REL "dialed in" the audio performance of my system improved substantially. Once in a while I'll forget to the turn the sub on and I immediately notice a qualitative decrease in audio performance. Night and day.

[@cbpersel]

@@nunopimentapaiva Yes, I used the high level connection which is unique to REL subs. Naturally, I had to spend about a week to "dial in" the sub with adjustments to the crossover and volume settings. As a result, it should only be working after the roll out of the low end of my Harbeth speakers, as well as reduce low end burden on the speakers improving the quality of its mid and high frequencies. I don't have objective measurements, but can say subjectively that the audio quality of the REL-Harbeth combination is remarkable.

Hi Tarun, Lovely review! Of course agree with you that the REL is still the Rolls Royce of subwoofers. I use the Sonus faber Gravis B1 subwoofer with my Sonus faber Cremona floorstanders painstakingly set at the correct settings for my 2 channel listening on both vinyl and cd. The Gravis B1 was one time the reference subwoofer of Ken Kessler who also wrote a rave review of it. A subwoofer definitely adds more body and definition to the music provided it is set up correctly. Fully agree with you on that.

[@howardskeivys4184]

2 years ago, I seriously upgraded my system, with the lion’s share of my budget going on a substantial pair of floor standers. I also purchased a pair of Rel T9I subs. The floor standers arrived about 5 weeks prior to the subs, so I had plenty of time to familiarise myself with the qualities and virtues of my floor standers as stand alone units. They’re damned good and reach really low. My hifi has to fight for it’s right to be in our family lounge. So, when the Rel T9I subs arrived negotiations with the aesthetics committee, AKA the wife, determined that they were to be located along the same wall as my floor standers. Experimentation proved that for optimum results at the listening position, placing them on the inside of each floor stander worked best. I too followed Rob’s advice for setting them up ending up with both gain and crossover set very low. For months and months I experimented with the phase setting. Taking Rob’s advice definitely created stronger bass, but the opposite setting gave a much more emphasis on the initial attack of the bass notes and I couldn’t make up my mind as to which setting I preferred. Last June I updated our sofas. The new sofas killed the room, deadened the ambiance. I bought a third sub. A Rel T5X. I know this sounds crazy, but I placed it on the floor, in the centre of the wall behind the listening position. I had to play around with the settings and reduce the gain on the T9I subs even further, but after a bit of experimentation. It all clicked, even the phase settings. A huge improvement to all dimensions of the soundstage and seamless integration with my main speakers. I specifically chose the T5X as the 3rd suv because it was to be boxed into a restricted area. It’s smaller physical dimensions and single down firing driver, just work. When I first contemplated installing that 3rd suv, I was seriously considering the Kef KC62 because of it’s tiny size and high performance, but my dealer steeered me away from the Kef. I am content with the current speaker arrangement.

Love the channel, And though I don't have the Tx7, I do have the Tx9. I never bought into the idea of a Sub in a home HIFi.. Always thought it would sound like the garbage that is associated with automobile systems. Loud, booming, and annoying. I was able to listen a bit at my local Audio specialist and just a day or two after taking home and setting up my new Rotel/B&W system, I went back and bought the REL. The fact that it had a 60 day return policy,, no questions asked, made me take the chance. All I can say is, WOW. Not one regret, Not even the fact considering price. This Sub totally changed my mind about Subwoofers. It's not inexpensive, and I think that's the magic. That's what makes the difference. The entire soundstage sounds amazing. Your review to me is on point and very accurate. You said it much better than I could write it.

I use a mini DSP to filter my REL subs at 80hz. Above 80 goes to my Magnepan LRS speakers. And because there is Dirac, the integrations is a peace of cake.

I have a minidsp SHD and I do the same thing with my Elac Uni-fi uf5's and my Rythmik L12. Really happy with the results. Room treatment is king, but using dirac can get you that much better. I only run the dirac curtain up to 200hz. I found running dirac all the way up would make my system sound dull and boring. How well do the REL subs integrate with your Maggies? That's usually pretty difficult, but I'd imagine the miniDSP helps a lot.

[@michaeldalrymple6907]

Love the channel! The one thing that REL subs do better than most any other subs, in my opinion, is that they disappear into your system. When I sit down to listen to someone else’s set up and can immediately identify the existence of a sub and even worse the position of the sub, I know we need to spend some time on set up. When a REL sub is properly set up, the resulting sound is an extension of base from your two main speakers. The best comment one can ever give a sub is that you must have a sub in the system because there is no way your speakers are producing that sound without some help. My REL in my two-channel system is located directly left of the listening position, certainly not a traditional placement, but I will wager most any amount that no one could identify its location. Thank you for all of your research and clever commentary.

Just added a REL T5/X to my vintage Musical Fidelity A1 Final Edition and Castle Chester combo. I had to re play this videos because it is so packed with information that makes sense now that I am working on optimal placement of the sub woofer, phase, gain and crossover points. I followed the recommended sequence and it is coming along nicely. REL comes with a nice booklet explaining all manner of connection options. This sub helps me get more our of my vintage system for a relatively small outlay. I do wish there was a remote control for gain. There are some tracks whose mix is so egregious that I have to walk over to the sub and turn it down. Once you have tuned the REL, it copes well with most recordings. This I believe is the magic in REL's proprietary filters. I find myself replaying all my favorite music and taking delight in finding nuances that I had never heard before. A question for the community. I can not find the album Sneakers track #4 'Cosmo...my friend' (1992 James Horner) on Deezer or Qobuz. Has anyone found it on a streaming service?

I am currently using 6 x 12" powered subs in a 2 channel system. People say it's overkill, on paper "yes" in reality "no". Using 2 subs was excellent, 4 subs was definitely an upgrade, 6 subs is basically perfection. I got the idea from REL the way they stack their subs, it might look overkill but in reality that's far from the truth. It's all about getting the setup right and it takes time and effort but it really pays off, I cannot see myself ever going back. The subs are turned down really low and are very subtle and at times you think are they even turned on when listening to music but in movies when there is an explosion and it hits you in the chest , WOW, yes the subs are definitely on. If you ever get a chance to experience a well setup stack of subs it's almost a life changing experience and it's hard to pull yourself away. Personally, it was money well spent.

Hi Tarun, Thank you so much for convincing me to buy a subwoofer, the Rel T7X to be more precise. It is now up and running and the musical improvements are quite something: wider and much deeper soundstage, much more separation between the instruments, piano’s sound like real piano’s, all string instruments come to life (not just bass or cello). All types of music sound much more musical. Some music which was just too harsh on the ears all of a sudden sounds perfectly balanced. Considering the price of one Rel T7X, the musicality improvements of my system is nothing short of sensational. Thanks again!!! I suppose this is bad news for high end speaker manufacturers: I’ve paired the T7X with my Rega Jura speakers of 22 years old. I don’t think I’m going to replace them any time soon (whereas I was contemplating buying the Harbeth SHL5plus XD). Rest of the system: Rega Mira integrated amplifier (also 22 years old), Roon on Mac feeding my Aurelic Aries (wirelessly), which is connected to the Chord Qutest with a linear power supply (the Farad Super3).

Thanks for covering this. My most recent experience with sub placement was with the REL T9x and Magnepan .7’s combined with components from PS audio. The result was wonderful in terms of creating greater dimension, depth and refinement to a wide range of music. Although interested in the smaller T5x and though they have been reviewed a great deal, I’m most interested in your assessment of the KEF Kc62 and the SVS micro 3000 for smaller to medium size rooms. More so now that I have a pair of Buchardt S400MKII’s and which already deliver well in terms of bass performance for a small speaker.

I have the same thoughts as you do here, Tarun. I think your room acoustics are not meant to host this specific subwoofer therefore the placement of it could be described as an equation with no solution (all other things equal of course). Maybe a couple of subwoofers (like the T5X or Tzero MKIII) that fire downwards may be a better match for your room as it is in this video.

Hi Tarun, thanx for this- as always - great review. Had the T7X to try at home only recently and can confirm the effect you mentioned: It not only adds bass weight and extension but also soundstage width and depth leading to an overall nicer smoother tonal characteristic of the system. The only caviat is that I felt like it is not fully catching up with the speed of my main speaker (System Audio with 2 small 14 cm/5.5 inch woofers). Which lead to a reduced dynamic impact especially with electronic music. I wonder if you experienced something similar, as I would asume the ProAcs being quite fast speakers as well? So my quest for a Sub that does integrate even better (maybe the smaller T 5X, etc.) and would love to see you reviewing more Subs on this channel. Keep going with your great work. Cheers Bernd

[@abritishaudiophile7314]

Thank you Bernd. Much appreciated. The T7X kept up with my ProAcs pretty well. I think there are two things to focus on. Get the location right and then makes sure the gain is not set too high. Crossover adjustments can be tweaked over time 😊👍

Also were you using the high level connection or sub out and line level? You only get rels claimed 7ms or whatever with the high level. I'm very sensitive to the delay. I'm a drummer and I focus a lot on that section when listening. I can hear when the bass player seems slightly behind when I know that live they were tight TIGHT. I've pondered that 7ms claimed response. If that's true, can I add some kind of DSP or processor to delay my mains by 7ms and offset that difference so they're firing even more exact? I do a lot of electronic music too. Some funk glitch going right now and the rel love it 👍😘

Recently added a stereo pair of these exact rel t7x. They are quite special, but being a newbie and this being my first time dialing in a stereo pair has not been simple or easy. I still need to do more experimentation with setup since I'm not summing mono (which would probably make it much simpler to choose a location and set gain/crossover with a single mono sub). Now I'm dealing with sbir that is mpacting the left and right sub differently. Also room gain and cancellation possibilities between the two. I'm getting better at improving the setup, but will ultimately do a reality check of my 'tune by ear' approach with measuring mic and REW. It's all a learning exercise and not so simple, but I see the potential reward as fully worth the time.

[@Jorge-Fernandez-Lopez]

I had the same experience. First one subwoofer, crossover just under speakers roll-off and phase for the loudest sound at the crossover frequency (with tones). Relatively happy: some tracks perfect with good soundstage, others not so well with strong room modes. My small room height is the same than the width; really bad room. Then I got a second sub, each one close to the speakers. Less room modes and better stereo imaging (no shift) and soundstage. I started to move my chair, front and back: big big differences. With the listening position set, I find out that I had a strong resonances at 34/68/130 Hz related to room dimensions. Finally, some sharp equalization at these frequencies ("sox" in GNU/Linux). A lot of work, but I won't go back. Great great review of A British Audiophile. Thank you.

I have been using a Velodyne HGS 15 for 20+ years and it's still one of the best subs made and still running great. When the Velodyne finally dies, I will perhaps try a REL.

Wow! what a difference across the board, not just low frequency. Even vocals sound better. A much more open sound. I only wish I could have purchased two of them.

Excellent review as always. I have had a Rel t2, t5 and t7 and they are excellent subs that better than average for their cost, but I wanted to try something different. When I made the move to Sim Audio monoblocs there were some connection issues with using it with one sub, but my dealer helped me work through those. Rel website and documentation didn't support what my dealer had suggested, but it didn't object or mention it either. I was a little fearful not knowing if I would eventually be covered under warranty by Rel or Sim Audio if something went wrong. I went out on the limb and tried a subwoofer that is known in the industry for Home Theater, SVS, but is not covered much on KZbin (unless it's hooked up to a Home Theater System) itself for two channel sound. I called them last year around Memorial Day and talked to one of the reps for 15-30 minutes on the phone. We talked about speaker matching, the companies' warranty and step up or upgrade program. We talked about my Kef speakers, and he looked in their profile and told me what the subwoofer would need to be sat at as a starting point. The SVS rep told me to install the SVS App on the phone. I had watched a KZbin video by Steve Guttenberg the Audiophilliac regarding the SVS SB4000 and how he had raved about it with small speakers. I called the SVS Rep back that day and I ordered the Sub, which was an open box at that time for about $1099.00. This subwoofer since Covid 19 and inflation is now $1499 for an open box and $1799 brand new. This sub is huge, but for an open box there was no damage to the sub and it looked new. I hooked it up through the subs XLR input and XLR outputs on my preamp. My sub is not against the wall but in line with the left speaker away from the wall, due to its massive size. Well, I eventually got things dialed in with the phone amp and all I can say is wow!!! I think the Rel was maybe a little more articulate, but not by much. The SVS SB4000 can be tuned to sound anyway you want and the bass drive from, Classical, Jazz, Rock, Rap, Reggie was a lot more impactful than the Rel. My plan was to eventually buy two of these subs, but I might not need to. The Kef R3 and the SVS SB4000 make such a stunning combination that I put plans on hold to buy the Kef R11. This sub was such a surprise, set up was so easy except getting it out of the box and picking it up and hauling it over to the set-up location. This sub is too big and heavy for a one -man subwoofer crawl. When it came to Rap/Reggie music the Rel was never enough and sounded clinical, but on every other type of music it was fantastic. There was a song on Billie Elish last Album "When we fall Asleep, Where Do we Go", it is called Bad Guy, the Rel bottomed out, I also tried another older Rel the dealer had with a larger woofer, and it bottomed out. I would have had to move up to about the 2500-3200 range to get what I was looking for especially with dual XLR. The Rel no matter how much I tried could reproduce this song with the bass impact that it was designed to have, but to be fair to Rel, the bass note was intentionally distorted. The SVS SB4000 took the note and didn't bottom out and reproduced it as intended. I have things set that with a fingertip I can easily go from -10 to negative -5 with a fingertip to match whatever the artist intended. This is also really helpful with Reggie Music. This is a revelation for me in particular because, I had prior to my purchase heard a SVS SB4000 in a Best Buy Magnolia store set up with a pair of B&W 803 speakers and at another local Audio Store with McIntosh Speakers and McIntosh electronics and in both set ups it sounded horrible, too much bass overpowering the regular notes. My Guess since the second store, wouldn't hook up the SVS SB4000 to a pair of Magnepan 1.7 should have and did tell me a lot about that store. It told me that on both occasions these two stores had the SB4000 not properly set up because my SVS SB4000 is properly migrated into my speakers and the bass sounds like it is coming from my speakers. I can play Audiophile music and non-Audiophile music and I get all of the bass notes that I crave, even from the demanding Classical Music that I listen to. If you are doing two channel and have small speakers, believe me, a sub is a requirement, if you have the space and want to hear what the artist intended, I learned this even from ECM Jazz recordings that there are sometimes more hidden bass cues, than you might realize and proper placement, tuning and in my case having the phone app controls, went along way. Having others listen after your setup helps as well. My final opinion is Rel and SVS are both great subs and Rel does have a better reputation because subs are all they do and they are quite good at it, but don't for a moment count SVS out because the SVS SB4000 isn't the SVS of old or the ported blow hearts that you see demoed in stores or KZbin, if you tune them right, the SB series is up to the challenge of competing with Rel or anyone else.

Great to learn about your experiences Sid 😊👍

REL is clinical, and that’s for sure. If you are a bass junky, REL isn’t the one. I had an old JBL sub connected to my system. Once I connected REL T5i, it didn’t seem to work. Meaning I couldn’t feel it much. I though there was a problem . Then realised after reading reviews that it was too clinical. For a stereo sound, I think 2 REL subs are better regardless of the room size.

[@sidvicious3129]

@@faludabutt8253 You know it's funny that you should mention this. I had two Vandersteen subs, that when the bass could be felt, (there just wasn't enough of it) it was just okay, but there was certain music genre that the Vandersteen subs couldn't reproduce properly. I had Rel's before and after that that I enjoyed more, but there was certain genres of music that there wasn't enough bass. The SVS SB4000 can take any note from any genre with enough force to be realistic and not bloated. The question for me is will I buy another SB4000 and the answer is if I get the same deal that I got, then yes a resounding yes!!! I can literally control the bass output from the seat of my chair with the cell phone amp and make the bass sound anyway that I want, but the sub is heavy, I mean really heavy. To get what I'm now getting in the REL Lineup, I'm looking at well over 3000 for one sub, but they are good, real good.

Picked McLaren instead of Porsche. Otherwise, our list matches. Have a pair of T9x's to go with the notoriously-hard-to-subwoof Magnepan 1.7i's. My dealer found a reasonably good placement well out into the room along the long wall. I've fiddled with gain and crossover to where I think they're about right. I'll trade clarity for boundary reinforcement any day. RELs are really the only major sub brand that can match speed with quasi-ribbon panels.

[@abritishaudiophile7314]

Thank you Michael. I like McLarens too 😊👍

[@earl007]

I can see clearly you are true music lover. The fact you have the same speakers and sub for so long proves you are not a reviewer who changes his hi fi as regularly as you change your undies. After many years of listening, changing bits in my hi fi here and there, for the past two years I have said no more, just enjoy the music. And that is what it is all about. Love your show and your knowledge is unbelievable.

[@abritishaudiophile7314]

Thank you Earl. That is very kind 👍😊👍

[@steverees1936]

REL are something really special and are made in my birthplace of Bridgend, S Wales. 😁 They will be my first choice of subs for my hi-fi system. I'm thinking of 2 T5x subs in my 16x11 foot room. One for each channel.

[@abritishaudiophile7314]

Cool 😎

[@MRMR-ss8el]

Hi Tarun - My answers were: 1) Porsche, 2) Rolex, 3) REL. 😀 Go figure! I have been auditioning an REL S-510 the past few weeks as part of my 2-channel system and have decided to keep it. It really does enhance the sound field in a non-obtrusive manner. It just seems to fill up the room and makes the listening experience that much richer, without really knowing that its even there. I just came across your channel and am highly impressed. Really well done videos. Bravo! A bonus learning in this one: “a pain in the jacksy (-sie?)” 😂 This American is going to get good use out of that. Cheers!

[@abritishaudiophile7314]

Thank you my friend. I look forward to “Jasksie” being included in the US urban dictionary 😂👍

[@joeygsaudiochannel3972]

I recently helped Michael from Poetry on Plastic dial in his "Little REL" along with his Harbeth 30.2's. EXACTLY as you described. Excellent Video once again my friend.

[@abritishaudiophile7314]

Thank you Joey. Much appreciated 😊👍

[@MrDishdonkey]

I have 2 REL Q150's and can't imagine listening without them. I've had one for over 20 years and I bought a second at a bargain price of £100 last year. Everyone who listens to my system comments now on how deep and wide my system sounds. I believe 2 subwoofers with high level connections a far superior performance to a single Sub. I'm interested in the delay you mention as mine are the same Generation as your strata so I could imagine I'd find the same replacing mine, but £2000 pounds worth of improvement over what I have I'm not so sure. If I get issues or failures then maybe but I think that money would be spent more wisely elsewhere first on my system. As always a great review with some clear explanations of how things work 👌

[@abritishaudiophile7314]

Thank you for watching and sharing your experiences James 😊👍

[@VictorZubakin]

Thanks for the review. Will add the REL to my shortlist of subs including the KEF KC62. I'm looking for a little extra bottom end to supplement my 40yr old Celestion 551 speakers.

[@abritishaudiophile7314]

Cool 😎

I purchased a BK Electronics double gem subwoofer. It has two 10inch drivers and I love it.

Thank you for sharing 😊

[@frankiep8262]

Just a quick note to say I very much enjoyed the music you suggested with regards to evaluating bass performance (even the Pan Sonic, LOL). I run Nautilus 805's with an SVS SB-4000 rolled off at 38 hz. While I'm not sure what you're hearing, my bass was weighty and articulate without being boomy/muddy. I think I have it dialed in as well as possible without resorting to room EQ and DSP. Anyway, I was blown away by Ellington's Afro-Bossa. Tremendous in every way. I don't know how this got past me (and I consider myself a jazz fan). Keep up the good work. It's appreciated.

[@abritishaudiophile7314]

Thank you Frankie 👍😊👍

[@AngelInTheDesert]

I have a REL T9i. I’ve gone on quite a journey in audio. I have been slowly transitioning from quantity to quality. I’ve since upgraded my mains and the sub is now the weak point. Dreaming about dual S/812’s

[@abritishaudiophile7314]

Cool 😎

[@CaptHotah]

This video was recommended to me by KZbin cause i watched several rel reviews. Great video you got a new subscriber. Planning to buy 2x t5x for my focal choras

[@abritishaudiophile7314]

That is great. Thank you for the support. Please let me know how you get on 😊

[@d.charlesberti9002]

How do you like your RELs? What Chora do you have? I have the 826 and would like to have a pair of RELs someday. I was leaning toward the T7... Do you find the T5 be everything that you need or would want? Thanks!

[@taylorwood4404]

Appreciate the in depth review, I’ve got a pair of Buchardt S300 MKII’s with a Rel T9x 2.1 set up and absolutely love it. Next upgrade will probably be to add another T9x 😂

[@abritishaudiophile7314]

Thank you 😊

[@EarlPartridge]

I got one just like this, it's probably not setup correctly, but o boy what a difference it makes! I love my Rel T7/X :)

I have always had a sub all the way back to 1995 when when I bought one of the original BK built REL stadium for a 24 hr club cafe I owned in Brighton. That sub has been with me all my life only having one cone replacement until a week or so when I got the amp rebuilt and put a new driver in it. At the same time, much to the disapproval of my wife, I also purchased a Tx7 thinking it would improve my cinema sound which it did. However since the Stadium was put back together it sounds almost identical to the TX7 apart from the Low LFE which adds some serious lows to movies. I have both subs set on separate wifi switches and when I toggle between the two with music playing there’s very little between them which is quite something for a 28 year old sub. Got to love the TX7 for its looks though.

[@wverlinden]

I'm running an SVS SB4000 in my living room setup with an NAD T777v3 for both 2.1 music (Roon) and 5.1 for TV. Speakers are Dali Rubicon LRC front, Dali Fazon LCR center and Dali Fazon SAT rear speakers. Maybe not the most audiophyle system, but it is discreet and I like the SQ (Dirac Live).

[@abritishaudiophile7314]

Thank you for sharing Win 👍

[@davehill9951]

Your price or should i say products are over and above my pricing. I have had a set of Mission 74i's and the 10 inch sub to go with it. Owned em for 20 years now and still makes me smile. Just bought the new Yamaha Aventage rxa2a and made a huge difference. Could i afford the Mcintosh 12000 not a chance at 15000 dollars., my car didnt cost me that. Great video

I have a car that toys with Porsches, I am attracted to cheaper watches (always scared of damaging my good looking ones), and I bought a REL Quake II after reading too many reviews recommending it over a Storm II. Very interesting video. I do agree with your way of setting it up, get it just a little too hot and crank it down one notch at a time until it sounds right. My amp manages the rolloff, the integration is amazing, it gives the illusion that the bass comes from the speakers themselves. I have set it in a corner with a tilted wall angle sitting above, and sound treatment around it. It sits on top of a thick wood slab, and this two details helped to eliminate resonance (the rest of the room is also treated against reflections and resonance). And a little ambience light on top of it. Throw anything at it and you forget that's it's there, literally.
