Denver,

I have to agree with you. I am also using a Yamaha in 2-channel mode and there is plenty of bass coming from the M60s. It is a lot tighter and less boomy than my previous Yamaha speakers. However, it has plenty of boom where needed. As I posted before, there are some tracks on the Titanic soundtrack (my wife put it on) that go way down to the low frequencies. The base rattled the room to the point that I had to check my setting to make sure the sub wasn't on.

Given my experiences w/ these speakers thus far, I have to wonder if this is a receiver settings issue for those stating that the bass is inadequate. IMHO, any more bass from these guys would start to muddy the sound for me and just be a distraction....Again, this is just my opinion.
