Unrelenting Fidelity. REL S510 Subwoofer Review!

[@pmizz7959]

I’ll just say… Nemo is spot on all…. I went from a pair of T7Xs to a pair of these… It was eye opening how drastic the improvement is.. The speed and clarity difference is immediately evident. There is 0 bloat to the bass. The scale is night and day… The old adage that you get what you pay for is totally relevant here

"And now, by the power vested in me, I pronounce the REL S510 a top-rated subwoofer." Thanks for the review, minister Nemo! Hope your other gig went well.

Nice review. I considered the S/812 before getting a great deal on a Carbon Special that I could not refuse. The S/S812 sounded excellent and the Carbon Special is a nice step up from it. Completely agree with your assessment of how well REL subs integrate and disappear. Your description of the bass emerging from ink black background, hearing no difference between the speakers/subwoofer and the sound coming from one place is spot-on.

Great review @Nemo Propganda. A few years ago, you were instrumental in influencing my decision to become a Rel customer with the review you did on the HT/1205, which I bought after yours and Rel team's gracious answers to my questions. Keep up the good work!

[@NemoPropaganda]

excellent choice, I still love my the HT range, great sub!!

[@ravington666]

Nemo you absolutely nail it when you do your comparisons, you dont just pick the obvious ! (e.g comparing to the JL audio). I'm never left frustrated wishing you had compared it to something that you didn't. One of the best parts of your reviews and so important to your viewers, keep up the good work 👌

[@DKLGalactus5]

I love the SVS subwoofers and, SVS has the best customer service. My SB 4000 subwoofer was having an issue after six years I contacted SVS hoping they would help me and they came through with flying colors they sent a new amp plate, and now my city is reporting mini earthquakes when my subwoofer is on. Again, thank you, SVS . Now that's customer service.

[@NemoPropaganda]

I agree SVS customer service is very good but why not put this comment on one of my SVS videos instead? I think it would be more helpful that way instead of on a REL video.

Wonderful! Thank you for this review, it was long-awaited. Based on your review, I feel like I should demo one when I’m ready to upgrade. Sounds like it ticks so many of my boxes.

[@JingoLoBa57]

Just placed an order based on this review. A demo unit here in Oz costing $3999. Thanks, man, for your honest and thorough reviews. They matter. Can't wait. Because its a 10", not a behemoth. Yet, it sounds large and refined. I had PMC MB2SE before; you can look them up; they were magnificent but just too big for my room. I need better bass than what the poor Harmonix are being asked to deliver. I must work on configuring the upgraded AV8805 I currently use as a preamp into my ARC D240 MKII power amp. With some amazing cables all around, I hope to help the Harmonix relax a little.

[@NemoPropaganda]

awesome, I hope you enjoy it as much as I did!!

[@cyberathlete]

Have 2 of these. One of the few subwoofers I own that I would never get rid of. I will use them till they die. My subs are: 4x Martin Logan Depth i (my all time favorite and I think one of the best subwoofers under $3000 period. There is absolutely nothing like this that I've heard. Super tight, hits super hard, digs super deep. There is not one thing I can knock on these not one). 2x REL S/510 (used in my 2 channel setup) 2x REL T/7x (used as LFE's for family room TV setup) 1x REL T/7i (for toddler's 2 channel setup in her room) 1x REL S/2 (in my home office) 2x REL HT/1510 (in home theater, work in progress) 1x Klipsh Cinema sub (comes with the Cinema 600 soundbar) (bedroom) Used to own: 2x SVS SB-1000 Pro (more emphasis on lowest octaves and not as refined in mid bass). 2x Klipsch R-12SW (can shake the house but boomy) 1x Martin Logan Dynamo 300 (gifted to my brother in law)

[@Birmingham_racing]

Been waiting on this review. The t9x was the best sub I've ever heard when it comes to bass quality. I didn't think this could be much better but you made me realise its worth it

[@tagtag-connected5263]

It’s not even close. The s510 blows away 9x or 7x. It’s a whole different level and plays harder and reaches deeper. You get a much bigger jump from 9x to s510 than going from s510 to s812. It is the sweet spot and s510 plays close s812 in deep bass but lighter and faster.

[@cyberathlete]

Ya S/510 digs much deeper and makes more pressure in the room. I own many subs, look at my post (sort by new) and the S/510 along with my Martin Logan Depth i are permanent keepers. Not gonna sell, will keep them till they die.

[@rockp5396]

Hey Nemo, great review and well worth the wait. I bought a S/510 in December that replaced a Rythmik E15HP2 and I completely agree with your assessment of their differences. The fidelity, detail, and lightning fast transitions make the E15HP2 feel a bit slow and less defined by comparison even though it’s a detailed and fast sub in its own right. At this point, I would give the nod to the S/510 because I value the detail more than I value ability to play lower and louder. S/812 next?

[@NemoPropaganda]

nice! yeah the e15hp2 is very capable, it has the transients of the much smaller T9X which is a serious accomplishment considering how large it is but somehow the S510 manages to say "hold my beer". I'm not sure I'll cover the S812, I've covered a lot of REL subs in a very short period of time and need to cover seme other brands :)

[@HopefulMarineIguana-so3ss]

@@NemoPropaganda Hi there, I personally think it’s perfect time to cover another Rel such as S812 sooner than later while the review of S510 is still fresh in your memory. For accurate comparison between the two models.👍

[@uclaxab]

I’m incredibly happy with dual S/510s for my 6000 cubic ft room. Started with one but smoothed out the low end extension especially at my LP with the second. Highly recommend it. Thanks for the review Nemo. Always great to get your honest off the cuff opinion.

[@Reggaebeatman]

Do u get some bass slam. I got similar room size thinking getting 2nd S510 however want a touch of bass slam so was thinking getting Rel 1510 Predator 2.

[@uclaxab]

Yes I did but I also had to tame certain frequencies because of room nodes. I didn’t have as much flexibility in placement of the 2 subs. You’ll have to battle the room regardless, but pure slam, definitely yes.

[@jagjitjosan2755]

Been waiting for your review on this so thanks for delivering Nemo !! I've watched many of your other subwoofer videos in the past and the only decision left to make is S510 or S812. Room is 5x5m, will take a demo from a local dealer and decide from there.

[@NemoPropaganda]

email REl and see what they say :)

[@Artemis_Prix]

As Nemo suggested, contact Rel. But, you're right on point to demo both. With that in mind, note my room is 25x48 ft with 12-18ft cathedral ceilings. Believe me when I say, ONE s/510 is more than enough to charge my room, and I only have it at slightly less than 30% power! It pairs incredibly well with my Heresy IVs. Do I want a second one...yes. But, only to smooth out some very minor nulls in my soundstage, but not because I'm wanting of more bass by any means. BTW, I am a bass head, but I just prefer refined, high-quality bass, over the flouncy stuff. Hope this was helpful. Good luck.

Excellent review. Thanks for your experienced insights.🙏

[@adden361]

Recently I decided that I wanted a new subwoofer. For the last 16 years we have used a B&W ASW610. I went to Best Buy and listened to the Martin Logan 1600X, the bass felt like an out of control nuclear blast. Then I listened to the REL T/9x for the first time. I was impressed by the sound quality. Then I heard REL S/812. I knew right away that was the sound that I was looking for. The REL S/812 is a great subwoofer but it's too big for my space. Then I started looking on KZbin for information about the S/510. After I watched your video, I decided it's the one for me. I have not heard it yet but, the way you described the features, sound quality, the difference between SQ and SPL subwoofers helped me decide to order the S/510. I also cross shopped JL audio, your analogy using cars as the comparison spoke to me. You sold me the S/510. Thank you.

[@NemoPropaganda]

wooo! Congratulations, that's going to be a HUGE upgrade for you!!! I hope you love it as much as I did, remember subwoofer break-in is real, try to give it a good 10 hours play minimum before you even think about judgeing it, you'll have to constantly turn it down as it breaks in more, have fun!!

[@hubertcumberdale3063]

Really enjoyed that review mate thanks! I have a very small room and am going to upgrade from a T7x, was going to go straight to an 812 but this has made me realise I need to try one of these first

[@NemoPropaganda]

If it's a music only system check with REL first or your dealer, their S line really are designed to work in certain room sizes. Series HT & TX can pretty much be shoved in any room. I'm just thinking if you room is pretty small a T9X might be the wiser choice. If you do theater also by all means go for the bigger S510 :D

[@hubertcumberdale3063]

​@NemoPropaganda hey man thanks for that reply. I have tried to put it out of my head but the way you describe this sub makes it impossible! I have been to my local hifi dealer and they are going to lend me one to try next month after I've done a couple more upgrades and I am hoping it can work!

[@NemoPropaganda]

@@hubertcumberdale3063 in home trial is the best thing you can do!! If you're not getting extension then the room is too small and you need T9X or 1205 MK2 instead. If you're getting good extension to 25hz or lower then it it's a good fit for the room!

[@Hysteric2006]

I love my s510. I went from T9/x to s510 and it added everything I thought the T9/x was missing. For a medium to largish room the s510 is fantastic. For small room the T9/x is also great. It’s all about size requirements with subs. If you have a large room get a large sub.. or two.

[@cyberathlete]

Nemo, this is something I tweeted to REL a long time ago as well. They used to carry a starting entry level S series sub in the last generation, the S/2 which was priced at $1499 and had all the performance features of the S series but in a smaller scale. It was a bonafide S series sub. The issue is there is no sub that fills the gap price wise or size wise between the T/9x and the S/510. If somenone wants something better than T/9x but not spend $3000 per sub, they really should offer a sub at $2000 that is S series but smaller scale. This is a serious miss on their part. Audi and BMW sell a tonne of cars, but their biggest sellers are the entry cars in the brand, not the flagships. Folks want the experience of the German car but not have to spend $60k+ to do it. BMW 3 series, Audi A3/A4 are their biggest sellers by far. They're the most feasible, it makes sense.

[@NemoPropaganda]

I hear ya but I'm not sure the S510 can get any smaller though.

[@cyberathlete]

@@NemoPropaganda look up the Rel S/2. I own this. It's -6 dB mid 20Hz (this was from the previous S line, before T/x). They can make a smaller S/510 sub with 8" driver and 10" passive

@@cyberathlete you don't thin kthat would get outperformed by the T9x?

[@CapnJack100]

I would think those interested in mostly music would easily pull the trigger for a smaller S series over the T9

[@adamswift1747]

Amazing review. I have an SVS SB2000 Pro that sounds so...ponderous. It can't keep up with fast bass lines. It's so frustrating. I was thinking of replacing it with a REL T9x. But now I want one of these! Would this overpower a 12x18ft room?

[@NemoPropaganda]

Since your question is about room size and which REL sub to get I suggest you contact them directly. They have more experience than I do with their own subs in various rooms but based off my experience I think you have the perfect room size for an S510 or T9X and it will really be your personal taste for output & extension that determine which is best. If you want a sonic upgrade without any loss in extnesion that would be the S510, if you don't mind giving up some extension the T9X is also outstanding and smaller overall but doesn't get as low as the S510.

[@ravington666]

The REL is probably the ultimate 10" subwoofer offering probably the best blend of SQ & SPL but price aside, the biggest issue for me is that its rather big for a sealed 10 inch.

[@NemoPropaganda]

nothing wrong with that, most people will like one or the other, very few people will enjoy both sides of the spectrum.

[@debontehond22]

Did you try the wireless module? Ow and diminishing returns is about less value per money unit and not that there is more performance for more money. At some point you are spending 5x the money to get the last bit of o,1% value

[@NemoPropaganda]

no, I do not have the wireless module. Yes I understand dimishing returns, I still have not experienced it is what I'm saying. I have yet to come across a product where it's improvement was very small over the price increase of the previous model. I'm sure it exists but I think the phrase gets thrown around anytime something is expensive as a way for people to cope.

[@rlcruiser709]

I really enjoy and trust your reviews! All of my audio equipment is in a rack in a separate room from my theater/music room. I only have a coaxial run to wire my subwoofer. Will the S510 sound as good if it is only wired with an LFE?

[@NemoPropaganda]

half the time I was using it I was using RCA cables, as long as the sub can produce the bass quantity your room needs it should sound great either way. Just keep in mind on many AVR's LFE out is for movie effects only. If you do wan't to run high level for some reason you can also tap off the back of your speakers.

[@svensvensson627]

If had the money.... I have had two REL, small ones and i have listened to several. They really are the best subs i have heard. Even the cheaper ones. But it comes with a pretty high price. But fidelity isnt cheap. Great vid.

Hey there another great review.. I am waiting for you to review the Rel Carbon special.. That will be interesting.

[@NemoPropaganda]

[@sierranuestra]

Great review as always! I have a couple of S812 in stereo, Im having some problems with phase settings, REL recommends you have to set the phase where it sounds louder,fuller and complements with the front speakers...i do that, but some times it sounds a little muddy and not clean ( set at 180) do I have to decrease the volume or increase the crossover of the subs? When I change to phase 0 the bass decrease a lot and its not punchy with a very low hz bass. Do you have any experience? Regards,

[@NemoPropaganda]

I have a feeling your freq is set too high, many people make the mistake of cranking the freq know to 2 oclock or higher on REL's, try leaving your gain where it is and bring the freq down in 2 click increments and see what happens. Ultimately no sub is perfect for every room and we all have some imperfections at certain frequencies in our rooms we just have to live with but hopefully this helps. With the S510 and most speaker pairings I had my freq knob only around 4 clicks so almost all the way down.

[@sierranuestra]

@@NemoPropaganda will try it. Thank you!!

[@andrewpeel912]

Great review, once again! I've been wondering how the proce equivalent rel would compare to the JL e110 (I had a lot of fun with my e110, but have moved on from it, now running a Dali euphonia as2 subwoofer, much more detail). I haven't heard the S line yet, I was kind of turned off passive radiator subs after owning a Sunfire signature subwoofer, that thing was awful.

[@NemoPropaganda]

I don't really consider REL a PR sub. I consider all REL's to be sealed subs. I know what you mean though, most PR subs just sound like compact vented subs. REL takes a unique approach in their PR design to the point they sound completely different which is why I consider them sealed subs.

[@lassesndergaard2018]

Great rewie 😃 How is the S510 compard aginst the ht1205mk2 in raw power output? I got 2 ht1205mk2 and is missing details and fines - And is looking at the 510 but will it make room pressure as the ht1205mk2?

[@NemoPropaganda]

I don't have a way to test that so I'm not sure, if I had to guess I think they are really close in terms of raw output but I think you should contact REL to get the best answer.

[@teknolojigundemi]

Hi, Thank you for your review. What is the best subwoofer integration ? High-level connectors or some a pre-amplifers has subwoofer output which filters signal and take some weight from main speakears. Btw a lot of time passed since S510 released, will be there newer versions? Buchardt announced new subwoofer. Hope you can review it.

[@NemoPropaganda]

I have the buchardt sub and will review it soon, as far as REL's future plans I don't know, companies rarely tell me anything early, and if they do it's usually only a few days or weeks early. As far as best subwoofer setup, there is no best, it depends on the rest of the system and the room.

[@CapnJack100]

Love it! I have really been waiting on this review as I don’t think you bullshit us. My question… my room size is 13x16 feet. My mains are Dynaudio Heritage Specials which are really quick speakers. Rel says I should be using the S510 even with my small room. I’m currently using T7x. Thoughts? What size is your room? Was the S510 an issue like too much? Thanks again!

[@BrianGarside]

T7x is probably the fastest/most transient in the T/x range. S510 will give you that and then some as Nemo mentioned. It will play louder so in that size room it will be far more impactful. You will likely have to turn down the gain. In comparison have (2) REL T9x in stereo config in a 18x24 with 8ft ceiling room and I had to turn mine down to blend them with my ATC SCM 19's which are similar in size to the heritage but have less bass. I think one will still work in that size room. 2 might be a bit much or just won't be able to leverage all of its' potential output wise unless you like it loud at times 100db.

[@NemoPropaganda]

I think your room is a good size for the s510 :)

[@Artemis_Prix]

Couldn't agree more with Brian, one S/510 is more than enough to power my room (26x48ft with 12-18 ft cathedral ceilings) when paired with Heresy IVs. Note, I only have the Rel set at a little less than 30%. One will be more than enough for your use case, and as Brian said, you'll likely want to turn the gain dial down even further to ensure ideal blending. Good luck.

[@mmdusa]

Jaw on floor. I can't believe it took you so long to get around to reviewing these. I started with the T9/X, then decided to get one of these. And yes, the difference was amazing. Wish I had the room for a "six pack". But I am very, very happy with the 2 I have. Are you going to keep it? Great review, btw!

[@NemoPropaganda]

probably not, I already I have a pair of T7X subs and I don't really suffer from the upgrade bug.

[@aceofspades6667]

Awwww yeah been waiting for this.. have a chance to pickup a pair used for a decent price. Just not sure if it was worth a premium over t9x.

[@krzysztofs3t532]

S510 also digs at least 10Hz deeper than T series. It is extremely important for building atmosphere and the feeling of the sound stage depth. Personally I think I would buy 1 better sub than 2 cheaper but lesser quality subs. Especially as the HT series "eats up" the T series.

[@user-tk7kz1fl2r]

It’s a good sub, but some caution. I love many genres of music. Everything is fine with level set to low. It reinforces the main speakers, subtly. If you set the base to a high setting gain, you will likely bottom out the sub even with rock, pop, jazz and that kind of music if the volume is high. Mine is at approx 6 clicks on gain and it’s more than enough. The base will be excessive anyway at high gain settings. It will be ok at good volumes. However, switch to rap…..the recording levels of this kind of music is way higher and bass is really big and powerful. The S510 will struggle immediately at high volume levels. I am very cautious when selecting hip hop or rap. This sub cannot handle that level of base at high volumes.

[@NemoPropaganda]

of course the S510 is still a 10" sub at the end of the day, a single 10" sub from any brand will have its limits when pushed.

[@walterpen371]

For many years I've only heard of excellent reviews about REL Subwoofers. A must have for serious audiophiles. Now compare them to HSU VTF-TN1 15" Subwoofer. The features, warranty and the price makes these a serious option.

[@NemoPropaganda]

I don't think HSU and REL have anything in common brother. As far as I know there are only 2 SQ brands for home subwoofers. REL & Rythmik, that's it. Everyone else either makes SPL subs or something inbetween.

Nemo mate another question. I know it is frowned upon to mix subs from different brands. I have a Kef KF92 which I adore. It has transformed music for me. I am however in that dilemma whether KF92 is fast enough. Now I am planning a 2nd sub and eyeing s/510 thinking I can somehow integrate both. My speaker are Kef R3 and 80% music. Do you think I will be able to make KF92 and s/510 work together? Are they vastly different in their approach? Thank you!

[@NemoPropaganda]

Yes very different, the S510 is a purist sub, no DSP and nearly zero group delay while the KF92 has a lot of DSP happening, if you add an S510 to your system you'll stop using the KF92 for music. You might still use the KF92 for theater for LFE but with music you'll end up disconnecting the KF92. I like the KF92 a lot for it's extension but it's not even close, you won't want to use both. It's like having a Camry and then you buy a Lexus and keep the Camry also, you won't drive the camry anymore no matter how much you loved it.

I have tested it myself many times and the result was always marvelous!! You can add a second S510 or go for the 1510 as you like, both will sound great!! in this video I compared all the REL ranges so this should help: kzbin.info/www/bejne/imTaqJKIi8upkKssi=gT7xaHRJdDUUiKTY

[@Reggaebeatman]

@NemoPropaganda Great vids and thanks for the Link....u think S510 better for music? i got S510 got yes amazing fidelity, and bass nuances...my Rel placed in Back rear 3/4 in room I dont get Nulls better EQ overall in a 5,000 cubic sq feet room, 18ft long. Reviews i seen say H1510 Predator 2 has also very good bass dynamics for music, maybe not quite as good as S510 however they say it will easily satisfy audiophiles ( like u said sightly more nutral bass vs S510) though digs deep even better for music once adding the REL Airship 2 wireless for stereo high level neutron. I tested the Rel S510 moving it to Front sound stage placed in Centre and wow it adds that extra dimension, however unfortunately I get big Nulls front dips at 50hz so thinking HT1510 to help fill in Nulls for a Duel sub setup and get extra Slam. Though thinking maybe still to S510 for better audiophile bass.

[@NemoPropaganda]

@@Reggaebeatman it just depends what you want more, if you want more of the same add a second S510, if you want to add a lot more weight down low go for 1510, both decisions are logical and good. You already have great fidelity with the S510, you can turn the 1510 freq down so it's just reinforcing the lowest frequencies. Have you tried asking REL directly? I think either way will sound awesome but I'm sure they will have the best advice since they make both subs :)

[@Reggaebeatman]

@@NemoPropaganda yeah thanks for your patience . .I will check with REL see what they recommend. Keep pumping those videos they're very helpful.

[@stevehuhta1876]

I enjoyed the review! It would be interesting to hear the S510, sounds like quite the sub! I had a Rel T9x and went to a Rythmik F12, not even close to be fair, the Rel paled in comparison in every category.

[@NemoPropaganda]

really? of course the F12 is a top tier sub, can extend much lower and play much louder but in regards to fidelity i felt the two were about equal.

[@stevehuhta1876]

@@NemoPropaganda Money wise they were pretty similarly priced, but it truthfully wasn't much of a fight once they were dialed in. Both were paired with the Buchardt S400 MKII. The F12 just sounded much better, especially with instruments, guitars, orchestra etc. I ended up going dual F12's and its been beautiful! I have a music only system, perhaps the Rel may be better in home theater? In the visual department, I'll give props to the Rel.

[@NemoPropaganda]

@@stevehuhta1876 oh yeah that makes more sense, I use Rythmik with my S400 MK2 also :). I had dual F12SE originally but sold one because the pair was absolute overkill in my room.

Nice to hear that! I'm also interested in upgrading from the T9i to the F12. May I ask how you connected both subwoofers? Have you tried using the high-level input on the REL? I really like how the REL integrates into my system-it completely disappears. Is the F12 as good?

Would love you to review the jl audio e112.

[@NemoPropaganda]

I already reviewed the E110, I don't think there will be any additional insight provided by the larger model. JL also doesn't send review samples so I'd have to buy it with my own money which makes revieweing it very prohibitive.

[@damonmaddox1313]

I own 2 S510 and I love them. IMO the only problem I have is it just stops around 20-25 hz. I believe these are more for 2 channel music vs a dedicated movie theater. If you are doing double duty then these will work great.

[@NemoPropaganda]

it shouldn't stop at 25hz unless your room is very short and you're simply too close to the sub, that's a common problem with desktop guys. I don't remember the lengths but 20hz waves are incredibly long. If you room is very short you can still get crazy extension but you really need to DSP the hell out of everything. I had a buddy who's room only had a depth of 8ft so that was a big problem for him, he eventually was able to get down to 10hz but it took dual 18's and loads of DSP.

[@Artemis_Prix]

Interesting. I own only one S/510 and it does an incredible job with music when paired with my Heresy IVs in a very large room (26x48 ft with cathedral ceilings). But, it's just barely acceptable for HT duty. For music, I have it set at slightly less than 30%, but when I watch movies, I turn it up to 100%. Entirely different use cases for sure, and perhaps not a fair comparison. But, I may eventually get a Predator solely for HT use. Before I do, I plan to get a second S/510 to see if that addresses my HT gap. Let's see.

[@NemoPropaganda]

@@Artemis_Prix woo that's a massive room! I'm jealous!! I don't think there are many 10" subs that would do that room justice so I'd say you're lucky if the S510 is even barely cutting it for theater. That size room is dual predators bare minimum!

[@NemoPropaganda]

@yamafanboy5514 most modern subs have a subsonic filter but I doubt it would be that high up in the freq range, for something like the S510 i'd guess its around 16hz but I'm really just guessing here :)

[@geohof]

Was the output better than 2 T9x’s for HT

[@NemoPropaganda]

since my entire focus is 2ch stereo I think you will get a more reliable answer from REL directly since they make both products.

[@shawnpetersen9429]

I would love to see what you think of a Bryston or Perlisten sub.

[@NemoPropaganda]

Perlisten is the $5000 one I was referring to at the end of the video :). I almost reviewed it but it comes on a pallet and that makes it a no-go for me. Based on it's design Perlisten looks like its more in the direction of JL Audio but I'm really just guessing here.

[@shawnpetersen9429]

​@NemoPropaganda good to know 😀 Thank you! I am trying to decide on a sub to go with my Bryston Mini T's. The Rythmik D15SE that I have doesn't seem to be the best match for my music only system. These Bryston's have been a pain to dial in. I was looking at the S/510, matching Bryston Mini T sub, or the Perlisten R210. I will probably go with either the Bryston or the S/510. But I have a hard time believing 2 8's will give me what I need 😀 Especially for $5k.

[@NemoPropaganda]

@@shawnpetersen9429 really? The E15 is an incredibly good subwoofer with world class fidelty and SQ, I'm surprised it's not working well for you. It may be too large for the room perhaps?

[@shawnpetersen9429]

Maybe. For what ever reason I just haven't been able to get it to blend well with the Bryston speakers. Some songs sound great, and others not so much. It wouldn't be because it's down firing, would it? On some tracks I can hear slight breakup or distortion and it goes away when I turn off the sub. To be honest these Bryaton Mini T's have been kind of a pain to dial in my room. I thought an all Bryston system would be great, but I'm not so sure now.

Hey all. I have T/7X at the moment. Looking to upgrade. 2nd T/7X or S510 or JL E110?. My room is 5M x 5M (I am in in Australia) and I listen at fairly loud volumes (95dB). Thank you.

[@tagtag-connected5263]

Get a pair of the S510. T7x is weak sauce compared to s510. Listening to Sam Smith Unholy track or Vini Vici Makes us Stronger and fully turned up it vibrates the house. T9x could not produce the same weight let alone T7x. I went from T7x, T9x and s510 and it’s not even close. Your family or house next door may tell you to turn it down. S510 are not subs you own in an apartment 😬. 95db with a pair of s510 in your house means your house is about to go for liftoff 😁

I have a Parasound halo, Denafrips ares ii which I’ll be upgrading sometime. People don’t think I have a sub. They just think my fronts go down really low. I have it blended beautifully.

Nice! I'm not surprised, there really is such a thing as too much sub for music systems and there are times the smaller model is better.

I owned a PC2000 many years ago. It absolutely still has it's place. It's a PB2000 in a different shape for those who need that. I wouldn't use one in a music system personally but it's a great LFE sub and I do know many people that enjoy using LFE subs in music systems. If you have a strong taste for exaggerated low end using an LFE sub in a music system maybe a fun option for some.

[@tagtag-connected5263]

S812s are overkill and s510s does almost everything 812 can do. The jump is not that big from s510 to s812. You need to go to carbon for next level but then you need the space to properly utilize the carbons

[@jamesoneill5810]

@tagtag-connected5263 carbon specials are £4000 gbp/$5000, so in my room, they'd be even more overwhelming,like l implied 1,S812 plus a HT1510 was an amazing combination,getting 2 identical subs in your system ain't always the best thing to do....nor is 2 rel HT1510's as the 1510’s don't do what one S812 can I've had every rel bar the carbon/reference series in my room and one S812 plus a HT1510 was by far the best all round sound I've had

[@coco-cola5491]

how does this compare to kef kc92?

[@NemoPropaganda]

KC92 is a very different type of sub, it's all about having maximum extension out of a small package and great for compact home theater where space is at a premium. The KC92 is great but a good chunk of the price is for the small size. The S510 is superior in all aspects of bass fidelity.

I have (4) S510's in stereo pairs to go along with Magnepan 3.7's I got to say REL is highly over rated. My main complaint is that the bass is "loose" not tight at all. I hear way more boom than impact. I started out with a pair of T9X's. There wasn't a night and day difference.

[@NemoPropaganda]

I recently bought a pair of Carbon Specials myself so at least we're both putin gour money where our mouth is :). As far as your experience my brother that is really not inline with most peoples experience. I STRONGLY suggest you get with your dealer to figure out wha'ts wrong, at this price point your dealer really shoudl be helping getting these dialed in perefectly. But for sure either something is not setup right or they're not a good fit for the room, getting 4 subs to play together well and with magnepans is no easy task. And the fact that you feel it was not a big upgrade from T9X further tells me something is not right, even REL haters know there is a huge difference between the two. If your dealer is not helping you please contact REL directly and let them know! Or if you prefer jump in my free discord and see if we can help you get things right because that setup should sound freaking awesome!!!

@@NemoPropaganda I have the top pair of S510's wired through the 'high' power input with the mains and top subs rolling off @ 70Hz 12db/octave. The bottom subs are wired into the low level line input and come in at 45Hz and are only for that very bottom octave. Everyone who hears the system is in awe, but I want a tighter bass that hits you-- like my JBL Studio Monitors. What I really like about the subs is the transition from the Maggies in the upper bass 'hit' region-- 120Hz. I have the X-over open all the way up on the top REL's. The low mids are wider, fuller and smoother.

[@NemoPropaganda]

@@keithmoriyama5421 you may want to experiment with micro placement adjustments, my carbon specials at first sounded a touch slower than I expected, I called REL to ask if that was normal due to the size and the said NO!! So after a few micro adjustments like .5" back, .75" to the left, slight angle adjustment, etc.. holy hell, the darn Carbon is indeed quick as hell despite its size :). Do keep in mind a lot of hifi is trade offs, often times that hard bass you're referring to comes at the expense of tone & texture. The guys who are obsessed with that tend to run pro audio style subs, the big trade off their is an absolute lack of bass below 30-40hz but you should be able to get plenty of tactile feedback from the S510 stack as long as your room permits it of course, we all know some rooms like to cut or boost certain frequencies, we all have some imperfections we just have to live with.

So what you're insinuating is people should just buy an SVS SB16 Ultra-an obnoxiously unrefined "boom sub" that's inaccurate AF on music and as slow and thick as cold molasses-for it's "app, features and price" over another company's subwoofers that you have "no" actual first hand listening experience with according to your own words, one that "seems good" but you just know it's "way overpriced" despite you obviously never actually having even heard one before🤔...That reads more like the type of dubious comment you encounter from people who like to just "shill" for a product's competitors.

I also believe subwoofers sound different after they've been plugged in and turned on for awhile, especially the A/B powered ones like the T/X range.

Spending 3000 Dollars on a sub with barely any output below 30hz seems crazy to me. If thats what you wanted most good tower speakers can get down to 40-30hz no problem

[@NemoPropaganda]

Hi time traveler, I don't think that's true or fair to say. Most towers don't do much below 40hz, I've seen a few that can get flat down to 30hz but they generally weigh upwareds of 300lbs each and cost well over $15k. If you're just reading specs sure, every speaker company claims their speaker can extend low, that doesn't mean it can. I think you maybe did not watch the whole video but at the end I said "some people just won't believe me" and that's fine but this sub gets down to 20hz. -6dB is simply another way to say +-3db, I know it's confusing but -6dB is the more technically accurate way to to say it. Either way REL has 4 10" models available starting as low as the currently on sale 1003 MK2 at just $599 so it's not like they only make expensive stuff. Most people think a Porsche 911 is too expensive, and most of those people have never driven one. Some products have to be experienced first hand to understand why they are remarkable.

the phrase overpriced is used when discussing value, value is a personal perspective and there is no universal or agreed upon truth so I don't really discuss those things with anyone who disagrees because its personal. It's like arguing about food being too spicy or not spicy enough, your personal taste makes your truth real for you.

But there are a bunch of crazy good affordable options out there too, REL themselves has the 1003 MK2 that is considerably more affordable.
