Third for the De Capos... if you're looking for a small speaker with impressive bass response and that can handle a good deal of power. 300 Watts is overkill, obviously, (I'm assuming your Classes is 300 watts) but the De Capo can play loud and full. See my system--I'm using 150 watts, and the speaker doesn't even blink.
However, if you want deep bass repsonse (solid response under 40 hz), no small speaker will do it. Look into subwoofers. If space is an issue, take a look at the Virtual Bass Technologies subwoofers (http://www.subwoofersolutions.com/). They are remarkably small. There is a review on Absolute Sound's AVGuide.com site.
