I know the latest Yamaha series power amps have built-in hp and lp filters, not exactly a perfect x-ver but they do work. So a possible setup could be, a pair of the compacts, run the line out from one to the external amp and another dedicated sub box...would be a pretty good system.

My contact at Bose reckons the actual RMS of the compact is about 100-115w rms give or take, so a pair of them gives you about 230 (and thats Bose rms so its pretty efficient) and then add 450wats of sub..could be a nice system .

They hit Australia in June btw...he reckons (but dont hold him to it ) around $1400 each.
