It wasn't really extra bass. There were times when I noticed extra bass out the Ascends, but since we weren't using a sub I tried to ignore that...as I know from listening to my M22's the sub does a great job of filling in those sounds.
Perhaps richer sound is a better descriptor? The M22 speakers seemed a little thin by comparison during Crash. If you are looking for more detailed description, I'll have to think on a way to explain it better, or perhaps someone else can jump in to help me out.

Overall, I'm still happy with the M22 and glad I have them...it really just depends on what you like and what you listen to mostly. For the most part I prefer the M22's, but there are songs that sound better on the Ascends.
