It would stand to reason that more drivers will result in more bass. My room is 12 x 24 roughly and when I play my M80's with an sacd I have to check my subs because it sounds like they are playing. I have my M80's backed pretty close to the wall and equidistant from the corners and they lay down some damn good bass.From everything I have read the M100's really pound out the bass. Craig should be able to answer this for you easily. I think the M100's will be as close to a sub that you can come without actually having a sub. Are you using an external amp with your M80s ,I ask because I am and it made a big difference over just my Denon 3311 receiver.
