Little help with REL subwoofers, please?


I'm not especially knowledgeable about subwoofers and I'd appreciate some advice. I've got a pair of Magnepan 1.7i placed in a small (long, rectangular) room. I had a hefty JL sub that shook the house but that I could never fully integrate. On a whim, I switched it out for a pair of the diminutive REL Tzero subs and the sound is vastly better. On some music, though, such as classical organ, I miss the growl and thunder. I don't feel like I need to boost the "upper bass" and I definitely don't want to muddy things up; it's really the deep rumble that I occasionally want.

If it helps, I'm thinking of a piece of music like Max Richter's "On the Nature of Daylight," which about halfway through delivers a broad, deep sweep of musical sound that I want to *feel.*

I'm mostly pleased with the setup and I don't want to reinvent my room's wheel or break the bank. And I'd like to stay with at least two subs and likely stay with REL. So I'm thinking I might: 1) add a T/9X or maybe a T/7X and perhaps keep the crossover low; or 2) swap out the Tzeros and replace them with a pair of T/7Xs. For now, a pair of T/9Xs is a budgetary stretch that I'd like to avoid (and it is a small room).

Would it be weird having two Tzeros combined with the much bigger T/9X? Would the T/7X produce that deep, enveloping bass? I'm not particularly good at reading specs but -6dB at 30Hz doesn't sound especially deep to me. (The JL was -3dB at 23Hz.) Or am I misunderstanding how bass works and would a T/7X go plenty deep in a small room?

Thanks and Happy New Year!

@pennfootball71 I don't hear any sense of these being slow thus far. I suspect Rel subs very difficult to make generalizations about since main speakers and amps have relatively large influence on how subs perform. So far, with my Klipschorns, the T9x has virtually no impact on bass performance per se, don't really reach lower, just a bit of db boost in freq. where in room response at my listening position begins to roll off. These all about sound stage expansion for me.

 

Going into Rel purchase,  speed was of utmost concern for me, assumed these might be slow. Using this reasoning I partnered with Ac receptacle and power cords that I know supply fast, tight bass, considering silver high level speakon wire if I hear some slowing in future.

 

If these are slow, my past subs and present Genesis sub would be slower than slow, even with dsp slower than high level circuit in these Rels. I'm also open to the fact that over time I may hear some sense of slowness, why I may wish to upgrade to Reference models at some point.

 

 

 

Such rubbish, no data and based 100% on this KH opinion. 
 

T series subs not fast enough and made in china I would get 2 S/510’s. Remember even if Maggie’s are affordable they need the very best in electronics and subs for much more expensive speakers to actually work right.

Rel S and Ref series are faster on specs, issue is whether one hears T as slow, if not than there is no problem. Same with Maggie's, I've heard them with a variety of medium to high end electronics, always enjoyed the sound qualities of these speakers.

 Generalizations aren't worth much in this highly subjective and individualistic hobby/obsession. And criticisms of China made components are political, what does that have to do with sound quality?  Furthermore, virtually all audio electronics have China made components within.

i am holding out for a subwoofer made in an islamic country myself, so it can synergize with my flying persian rug 😂🤣😅😉😆

wtf

Integrating a subwoofer with fast Magnepans can be very difficult with "conventional" subwoofers.

Things that help

- sealed sub

- smallest driver possible that can still give 20 hz and below bass extension (i.e. serve as a "subwoofer")

- Servo controlled "fast" driver (if possible)

 

2 possible options emerge, that could work better for your application...

a) Rythmik FM8, smaller dual 8 inch drivers, that have Rythmik’s servo control support.

b) KEF KC62 (dual small, fast 6.5 inch drivers, no servo support however)

Note: Both these small subwoofers can give you bass extension under 20 hz (i.e. these are unique offerings). Both can also serve as midbass units, if needed, If you have multiple subs set up around you, you won’t be able to localize much by increasing crossover frequencies. You could also try shooting for relatively "nearfield" locations to your listening position with small subs (to add increased perception of tactile impact/feeling of growl, thunder).

There are many other "small subwoofers" out there, but, there is no point in getting a small crappy subwoofer that just gets down to 45, 50 Hz.
