See, that's where your system is gonna suck compared to mine . My powered 150W sub will provide me with bountiful lows in my well-damped, 1000 cubic foot office. So I guess you'll have to up me by buying a 600 \:\) .

What do you call higher volume? What kind of SPL are we talking about? When you have your soundcard turned to max, what time is it on the amp's knob? How big is the space you have them in?

If I'm good with a half watt in my 4,000 cubic foot space, does that mean that I'll be happy with a tenth of a watt in my office \:\) ?
