The MB2s I have access to have 4 Bryston monoblocks behind them. Bass is not as pronounced as you might think but is tuneful and extended (I think many people are used to and enjoy a bloated bass). Oddly he uses a PMC sub to add a bass hump! ( I turn it off and he hates me for it).

I think many home users (well, I) prefer a little more warmth and fullness than most monitors offer.
