REL T9x Subwoofer, Most Musical Subwoofer Money Can Buy!

[@AudioElectronicsChicago]

can't go wrong with the REL products

[@MarkLloyd-yo4li]

I had to watch this again. For me and all ive listened to over 50 years I dont think any other company makes a musical subwoofer as good as REL. For AVR useage i dont know . I use a ported SVS for movies that I don't enjoy with music . Im enjoying twin T9x subs on my Focal Choras . Very happy . Great video again .

[@ChaiBearProductions]

Looking to get one of these for my LS50 Wireless II. I had the T5/x in the past and it was a small powerful beast and did much more for the sound than just adding bass. Everything was fuller, more dynamic and the soundstage and midrange opened up significantly.

[@brentcollins9727]

I love my T5

[@willbrink]

I am listening to one now, will likely return it. Ordered another brand, will compare them shortly.

[@Pentenfi]

A passive radiator design is not "a sealed box with extra bemefits of a port". It is by design like a bassreflex system with extra suspension of the passive radiator. It does not have better group delay than a bass reflex enclosure, actually it is usually the other way around. What makes it special is that designers can get away with much smaller boxes and still have low tuning frequency

[@madcrabber1113]

very good Johnny, you get a star 😂 😂

[@HomeTheatre101]

Getting ready to drop a review on mine! The small size is very deceiving. Pairs beautifully to my B&W 606 S2!

[@Tharbamar]

Great choice!

[@Whatisthis94]

Thank you. Just got the Rel T9x

[@surasiri117]

You don't even need to play music with bass. A song with only vocals or piano sound you can hear differently good sound with REL

[@ChaiBearProductions]

Exactly. The whole frequency range is effected. A nice warmth and body to the sound is added.

[@hzchuan]

really like REL product, I think it present bass more natural and clear, nice choice!

[@WWeiss-nv5vz]

Great bass demo tracks! Thank you

[@LS-ti6jo]

My only complaint of the T9's is that they should have reference marks behind the three knobs so owners don't have to count the number of clicks of each knob (which is a pain in the A. .).

[@Skye_the_toller]

If it is close to a wall ( as it supposed)… you cannot see anything in back… so click is still good ;)

[@sunshine242-l4y]

I too am a little confused with the frequency response. First of all, thank you for showing that. From the looks of it, it seems to drop off like a cliff around 85hz for both the speakers and then with the subs. Almost as if there is some high-pass filter going on. Or that isn't the best location for producing frequencies 80hz and below. Or something else? I found for my dedicated rectangular room (9'x14'x7.5') that dual subs next to the speakers up front didn't produce the smoothest bass and a sort of diagonal setup was much better. So I really think it's room dependent but perhaps it's just my room.

[@Tharbamar]

Please remember I measured it from 10ft away, yes it’s all room dependent, I would use single center sub if I have room like you have. Thanks

[@JamesWilliams-gf8gm]

Good video. An external highpass crossover with a higher crossover point (60hz-ish) would take the system to an even higher level.

[@RamJamSky]

Rel actually recommends the s512 on their site to pair with the r11

[@vinodlingamsetty]

Yeh your right

[@alexandruhutu1307]

Hello, please give us the REL T7x setup for bookshelf speakers like the Buchardt.

[@vikrambhaskar7976]

Hii tharbamer! I was just wondering if you can make a video on how to connect subwoofer to stereo amplifier. Most amps don't have dedicated sub outs so an other option is to use speaker level connection but it's very confusing especially when subs have only one set of binding post. A video tutorial/ demo on this will be extremely helpful😊

[@supes323]

Im a little confused by the in room frequency response graph. I would have expected more of a measurable difference in the lower frequencies (red line) as it doesn’t appear you have much low frequency extension? However in the sound demo you can clearly hear some bass overlap between your kefs and the subs.

[@Tharbamar]

I understand, probably due to recording microphone was picking up more room than measurement one, I have figure out how to match them accurately in the future, thanks

[@DSupremeLounge]

Thanks! I just ordered 2 last week. Looking forward to mating w/PMC towers.

[@Tharbamar]

Great choice 👍🏼

[@John-hl6er]

Hi May I ask how you got on with the T9x with PMC? I have the Twenty523i and wondering if they can keep up. Many Thanks

[@DSupremeLounge]

@@John-hl6er they’re a great match

[@John-hl6er]

That’s what I wanted to hear :) I’ll set up a demo. Thanks for taking the time to reply

[@thomasmetcalf4642]

I too have Rel subs (two 212/SX) and love them. I've paired them with Sound Labs 745 electrostatic speakers driven by Pass Labs 350.8 amp. Have you listened to Pass Labs gear? I think you'd be very impressed. Thanks for the videos!

[@Nightjar726]

Time to get a mic and REW to integrate those near perfect with your speakers. It does make a serious difference. And takes out the guess work. Much faster than doing stuff by ear. And way more accurate

[@Tharbamar]

Sorry I’ve been doing REW for long time, thanks for the advice but I prefer to fine tune it with my ears, measurements don’t really matter in the end because it doesn’t know my taste, room and system like I do.

[@torus186]

Those KEF speakers really didn't need any sub input IMO. A smaller sealed enclosure would have been better to test here.

[@PumpUptheJam81]

Love these subs, but the REL logos all over the unit are tacky. Thankfully it appears they are getting the memo on their newly released product lines.

[@7Limousine]

Dear Tharbamar, i am very interested to buy the Accuphase E-4000 and want to chance my subwoofer from focal, the SW800 cobalt, into the REL T9x subwoofer. What is your advice in this combination? Thank you very much for the advice already.

[@DjJeffo78]

I usually use Drum n Bass to test out subwoofers sound quality. But I did have a an old CD and Cassette that I use for “Sound Tuning” for subwoofers. Not in my possession anymore. Great video by the way! 😁🙏🏼

[@alextsibanoulis122]

not the greatest pairing in terms of timing but definitely improves the 3D imaging of the sound. a pair of T7x might have worked better in this setup , with every respect in your reviews as i am a big fan of yours!

[@keithmoriyama5421]

True. I am always surprised that a sub can change the entire presentation of a system.

[@BrianGarside]

Why would the T7x be a better pairing? T9x has more output.

[@Musicman369]

I'm now thinking of adding a 2nd sub which will be a T7x I just don't understand the benefit of adding a 2nd one.

[@Tharbamar]

Benefit of using two sub is more even smoother bass quality in your room and bigger sound scape.

[@andreasmoller9798]

I think my Arendal 1723 1s is insanly musical and there is so much power and grunt when i need it to, i dont doubt rel t9x is s very good choise, its very limited in output

[@andrefortune8278]

Night and day with subwoofers

[@mikrophonie5633]

Fun game : Take a drink every time he says "Y'know".

[@vinodlingamsetty]

How’s the performance with movies? I have R11s as well. 50%movies 50%music. REL recommends to pair R11s with s510. I’m leaning towards one t9 now and one more later

[@Tharbamar]

I’ve watched a few movies like Transformers The Last Knight and Mission Impossible Fallout etc in 2.2 set up, sounded very impactful and impressive, T9X is about 90% of S510, actually developed based on S510 technology and know how, dual T9X is better than single S510 for me, thanks

[@marklloyd4153]

Do you think these pair well with the Focal Chora 826D for mostly music primarily ,& secondary for my AVR for movies ?

[@giangvu7902]

How did you you connect it to your amplifier without a pre-out connection? Using the speaker line level, how did connect the black wire to your amplifier. Thank you!

[@Tharbamar]

All connection were made at speaker terminals, black goes to negative, Yellow and Red twisted together(each sub) connecting positive terminals, for single sub you have to connect yellow to left positive red to right positive terminals and black to one of negative terminal, that’s the best way connect for 2 channel system, Thanks

[@luch2372]

Hi Tharbamar, thanks a lot for all your videos. I am the owner of a T/9x and I want to change the high level cable by a better one (DIY). What cable should I use ? (Canare 4S11 or other). Thanks a lot ! Luc

[@Tharbamar]

Hi, you can also use Canare 4S11 or Mogami W3104, thanks

[@luch2372]

@@Tharbamar thanks a lot for your answer. I made the cable with Canare 4S11 and Neutrik NL4FXX-W-S connector. It works well

[@summerrr1]

Do you think I can get away with just one of these if pairing with B&W 706 s2? I don’t particularly want to spend thousands on subwoofers. My room is approx 25x15ft.

[@Tharbamar]

It will be totally fine with one subwoofer in your room.

[@f430ferrari5]

I personally don’t like the concept of 1 subwoofer with bookshelf speakers. Mid-bass hard drum kick would be lacking but again it depends on the type of music people listen to. If one chooses a smaller sub and that sub is placed in a corner then it would appear that the drummer is in the corner. Some bookshelf speakers can produce a decent amount of bass so 1 sub might work. Better to start with 1 sub and if not satisfied perhaps buy another.

[@summerrr1]

@@Tharbamar thanks, got one today and it’s great 👍🏻

[@szeyu5688]

Just bought 2 t9x for music listening, can i cut the high level cable shorter? They came with 30fts, but only need 8 on each side. Thank you

[@Tharbamar]

Using shorter cable shouldn't be problem.

[@VJA74]

Whoa! I thought R11 was another sub that sounded better than R9x!😅

[@martindy3]

Curious why you’ve opted for the T/9x compared to REL’s recommended sub pairing for your KEF, being the S/812? Have you listened whether the SQ difference justify the additional cost?

[@MrBlur510]

I wonder the same thing, there is a comparison put out by REL saying that even 1 s510 will be better than 2 T9x.

[@robk5745]

They are very expensive that’s probably

[@paulbaker4941]

It's not rel have another line to this, these are the entry level

[@efrainl]

HT series is the "entry level". T/x line is midrange. "S" series are their top of the line.

[@MrRosscoz]

The Rel’s are a great sub, but the jl audio e10-12 pip them I reckon

[@m.j.s.3838]

Thanks for the video, Tharambar. For music, I have two REL T5i in an 18x24x8 room with Spendor SP2/3r2 speakers (or with Elac ARB-51)-very good results but not quite the last word. Do you think exchanging my dual small subs for a single T9x would be a worthy improvement, or would I need a pair of nines?

[@Tharbamar]

T9X will improve in speed,response and clarity, you may find it even more musical than what have, thanks

[@audioconnection4450]

I always like 2 woofers as it blends better without excitement of the rooms nodes or making the room heavy and spoiling the main speakers midrange clarity

Why’d you go with the T9X when the site calls for dual S/510 with the KEF R11’s

[@alexfoxpoker]

Hello! What is better for music 2xT9 (10'' 2x300W = 1 10'' 600W?) or 1xS812 (12'' 800W) ??? 2x10'' vs. 1x12'' ??? (Not 1xS510 is 500W, and 2xT9 2x300W plus two channels and A\B class). Or 2xREL S5 ? (2x12'' 2x500W) How much difference does the sound between the S5 and S812? If you don't count the volume? The price differs more than twice. Or 2xCanton Power Sub 12 ??? (2x300W vs 1xS812 800W) price 4x but what quality of bass? 🤔 2xT9x (10'' 300W A\B) vs 2xS5 (12'' 500W D) at the same cost ??? 🤔🤔 But here's the question: does it make sense to have two subwoofers if the crossover frequency is 40 Hz (after all, frequencies below 37 Hz are not localized by ear)? And if the crossover is set higher, how much better will the sound be in stereo? 🤔🤔🤔

[@Tharbamar]

Two sub is better than one for more balance bass quality, for the models you’ll have to check with REL based on your room size and needs.

[@Reggaebeatman]

This sounds like my type Sub. How do u think only 1 x REL t9x sub would sound in a larger room (20f wide x 30 feet long). Seated listening position is approx 15 feet from Speakers. I am big on high quality music fidelity, wanting big sound stage and prefer great bass and mid range articulation. do like playing gaming MW Call of Duty etc , low end rumble would be nice. HOW does it perform with film EDGE of TOMORROW? I read not many subs can handle the intro. Hi fedility music for me is a higher priority....SO this looks like great choice. To complicate things i listen to Classical, Jazz, Rock, Blues.....and Bone Crushing Metal. Thanks for the Fantasic review!!!

[@Tharbamar]

I would suggest you to try minimum 12” for your need.

[@Reggaebeatman]

@@Tharbamar thanks i guess this would take me up to the S/510 or better S/812 which has 12 inch driver.

How does a single T/9x compare to running dual T/9x?

[@Tharbamar]

It can sufficiently provide you good quality bass if you can set them in the middle of two speakers but low end bass response is more impressive with two than one subwoofer, thanks

[@robertwilliams1215]

The more subs you incorporate the smoother the bass response becomes throughout the room. They begin to disappear and will image better. MiniDSP HD 2X4 is a cheap and amazing tool that will not only transform the low end of your system ( with multi subs ) but your complete listening experience. Best $300 ( with Microphone ) I've ever spent on my system.

Look at HT range for Home Cinema sub low frequency effects Most musical instrument recordings which the TX range is focused on do not go anywhere near 20 hz anyway
