Adding a Subwoofer - REL T/9x?


I have a combo 2-channel and home theater setup. The 2-channel setup involves B&W 801s (gen 1 circa 1980), Krell KAV-250p pre-amp and Bryston 9B-SST 5 channel amp. While the woofers in the 801s are big, I thought adding a sub would give the system a little more oomph.

At the same time, I have an Integra DRX 3.4 hanging off it all for home theater (HT) only. I use the home theater bypass on the Krell to access the mains. I was looking for a sub that would pair well with the 801s and even be able to be used both with the 2-channel listening and HT. AI kindly suggested the REL T/9x with dual simultaneous connection capability.

Budget-wise I would say trying to stay under $1.5k and thinking only 1 sub at the moment. I had a massive sub previously that I sold (was never really happy with it) - a Power Sound Audio XV15. My room (non-sound corrected, plain old living room) is 15'x23'. I am not wed to the T/9x and used/older is perfectly fine. I like the idea of a dual hookup to use with either 2-channel or HT. I don't want another piece of furniture - an overall smaller sub is in order.

Hit me with those ideas!

Talk to REL directly and see what they recommend. My room is about the same size as yours with 10' ceilings. Thats a fair amount of cubic volume to excite.

My two cents: 

The Rythmik F12 deserves a serious look here — available new around $799  and frequently turns up used in good shape. The F12SE (servo-controlled) pushes closer to $1,100 new but is worth it if you can find one used.

Why it might work: The 801 Gen 1 woofers go low, so you don't need the sub doing heavy lifting but integration. Rythmik's sealed servo design  tight and will blend well, I think.

The adjustable phase is genuinely useful. With large speakers that have output below nominal rolloff, fixed 0°/180° phase switches are often a blunt instrument and you end up with either cancellation or reinforcement at the crossover point depending on your room placement. Rythmik gives you continuous 0–180° phase adjustment, which lets you dial in. 

The REL T/9x is fine but you'd be paying a REL premium for roughly equivalent performance. Used F12 or F12SE in the $500–900 range is a better move.

Thank you for the input. @gkelly that link seemed to go to REL’s home page. You have me curious as to what you were suggesting. I was able to borrow a T/9x and play with it a little today. First impressions are very positive.
