Do I need a subwoofer?

I do think it’s strange, though, that you’re using an SB2000 in a "fairly high-end" system. You need to increase your sub budget, there’s much better performance available for (in Rythmik’s case, at least) not much more money.

@shooter41 No, my feelings not hurt in the least. I transported my SB2000 from my HT in my family room just to see what it might add to my 2-channel system that consists of a Musician Pegasus R2R DAC, Bryston BP6 pre, McCormack DNA-0.5 RevA amp, and Soliloquy 6.2 speakers. The bass foundation was obvious, but the expansion of the soundstage in all directions along with improved imaging even with the one sub properly dialed in was pretty amazing and adding another I’d have to assume would improve things further still. I’ll take two SVS SB1000 Pros for significantly less $$$ over one comparable Rythmic or REL any day as I think two “lesser” yet still very capable subs trump one “better” sub, but you’re certainly entitled to your opinion.

Agreed, two subs are usually going to be better than one, even if that one is generally a more capable model, but with the rest of your system you really owe it to yourself to step up to a better pair.

Gee Scooter, thanks so much for your prized advice.  I’ve reviewed high-end audio for about 20 years, so when I’m ready to add a couple, or even better a swarm, of subs to my 2-channel setup I think I’ll be ok.  But thanks so much for your thoughts. 

@soix Dude, you asked. I had no idea I was advising audio royalty. 🙄

@shooter41 I didn’t ask.  You offered and I responded in kind.  Not royalty, just someone with some experience.  Your move chief.
