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!

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

wtf

 

@northman

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.

 

@deep_333, thank you for the suggestions. I've spent the last couple days reading about Rythmik subs. I'm impressed by what I read about both the F12 and the F8, but at 65-75lbs, they may be too heavy for me--but I appreciate the recommendation.

I don't know how small your space is, but mine is small (12x10) and I just put in two REL T/5x subs.  They were easy to integrate with the Neutrik Speakon connectors.  They move enough air to shake the floor and my listening chair when I turn it up (my neighbors likely don't care for it so I don't do it often).  I looked at Rhythmik as well but they are just too large for my space.  The RELs are the perfect size for me.  Since I bought two I asked the dealer if he could give me a discount and he did at 10%.  If you sell the two TZeros and buy a pair of T/7xs you might be able to swing a discount as well.  My in room performance for the T/5x is probably closer to 25-30HZ.  I've measured using REW and it's around -3db at 30HZ and -6db at 20HZ.  I am quite pleased with them.  They are fast and tight and have the sound I was looking for.

@jastralfu      I've measured using REW and it's around -3db at 30HZ and -6db at 20HZ.  I am quite pleased with them. 

As a past REL user I'd say even the manufacturer would find your measurement quite spectacular.
