I guess that I had a similar experience, Mully. The first few times that I listened to the m60's I thought I was missing a little bit of bass. I even considered getting a sub. After a few weeks though, I came to like the sound better and better the way it was. Recently I downloaded some songs from iTunes with lots of bass (mostly techno stuff) and realized that these speakers are capable of producing tremendous amounts of LFE when asked.
When I fill out my system to for home theater I'll get a sub, but until then I'm very happy with what I have.
