bupton, you will have to demo both products to see if there is a differance that you can notice. As for quality of the bass B&W will knock around the SVS but most people only want SPL.
No offense but have you actually
heard an SVS sub?? If you had, I don't see how you could make a comment like this (or perhaps you just didn't have it properly positioned and calibrated in your room). Don't get me wrong, I'm a HUGE fan of B&W. In fact I have a pair of DM602 S2s in my little HT (with an SVS PB10-ISD sub) and I really enjoy them, plus my partner in my live sound business has an entire 5 speaker set of B&W 600 series with an SVS PB12 Ultra/2 and the sound is stunning.
But while I haven't heard every sub B&W makes, and there's no doubt they all feature great sound quality, as a professional sound engineer I trust my ears, and they tell me there's no lack of quality with SVS subs compared to B&W. They're amazingly accurate, clean, and powerful, and seriously -- why would you pay so much more money for a B&W sub just to try to equal the performance of a much less expensive SVS?? That's just silly. My PB10-ISD replaced a borrowed B&W ASW500, which of course is an older, tiny, totally underpowered little 10" sub that could never be expected to compete with the SVS -- but it still cost $500 new!!!!!! I paid less than that for my SVS delivered and there's just no comparison. You'd have to pay at least $800 - $1000 for a B&W that could even begin to compete with my little SVS for quality OR volume -- and at that price point, you can get a much nicer SVS.
B&W's speakers are SWEET but for subs, look to the true experts.
