Rel Subwoofer questions and help


Hello, 

I recently returned to the audio hobby after years of using a modest system of Kef LS50 meta speakers driven by a high end home theater receiver. Now I'm pretty far along in my journey of assembling a home audio system where I can relax and be immersed in music (as well as tv shows and movies).

I'd love to know if any of you can comment about Rel Brittania subwoofers compared to Rel's current lineup. I own a pair of Rel B3 subwoofers now and just recently put them in my system using high level connections from my integrated amplifier. Stereo subs appear to be the biggest opportunity for significant improvement in my system today.

Will the Rel B series hold back the performance of my system? I have an incredible local audio dealer that I'm grateful for. I have heard the T9x in their room several times. Without buying a pair I don't know if there is a way for me to find out. I'm hoping some of you either own or have owned the Rel B series and can comment on using them in 2026 vs the modern lineup of T9x, Classic, S series.

Is running different Rel subs together can work well or is best to run a pair of the same model. The primary reason I'm asking is there is a Rel B1 for sale in my area but it is a single subwoofer. I am curious about pairing the B1 with one of my B3 subs. Might be a bad idea but I'm curious if that is actually true.

Thank you for your help!

Unmatched REL subs work fine, and I've been using them for decades. Currently my main system uses a new Classic 99 with an old Q150e...superb results, and the simple phase adjustment also works like it should.

I do have 1 small sub in my small home theater, 5.1, just for dinosaur stomps, big soundtracks, btw, anybody familiar with the movie ’Domino’. Love that soundtrack.

Adjusting my manual controls, on the back, is a PITA, because of where I put it. I sit right next to it, when balanced properly, I don’t know it’s there, but, sometimes ...

 

I need to yank it out of there to get to these controls

I would want remote volume control, even after initial setup, whether 2 channel, or video surround.

do any have remote controlled crossover points?

PS.

I enjoyed my REL T/9x paired side-by-side with Harbeth 30.2 XD. For that application (simple bass extension) variable phase wasn't necessary.

In my current application, I needed to deal with nulls and asymmetry in a listening space that opened up into a large open plan living space, as well as pressurize that space, which meant placing the subs behind the main listening position. 

In this case variable phase adjustment & multi-band EQ was absolutely necessary.     

Not ever speaker needs a Sub/Subs....But every audio room does! 

I bought my Subs (REL S 212s) as the last part of my system & room after ten yrs....the last piece of the puzzle.  I did not buy them for my speakers and more base = which they do; but for my room. Huge difference: soundstage is bigger, nuances are more detailed, more depth...feels more like I am at a real concert vs a audio room.

The room/space improved more than the lower extension for my speakers.
