Kordeo. There are two reason I can think of that you would think the M80s lack punch: you are used to a speaker with a mid bass hump that exaggerates the kick, the speakers are in a position that is creating a significant dip in mid-bass response at the listening position.

Here's a bit of useless trivia. My M80s have a LOT of kick when I listen from the bathroom. Room acoustics can be funny.
