Jazzdude, I don't have any personal experience with the 6, but what you report sounds an awful lot like a set-up/room interaction effect. Just based on common knowledge, I would hazard a guess that the biggest deciding factor between these two models could well be room size, not necessarily amp power per se. I would also think that in a room which could accomodate either model, the bigger speaker would not only yield some more bass, but also higher volume capability, all other things being equal. Akaddict, maybe you should specify the room dimensions, what types of music are listened to most, and how loud you like to listen. But I will say this from experience: The 2.2's cannot go really loud, which is more evident the bigger the room, so if you've been alright with their dynamic range in your room up 'til now, you may not need (or be able to get the most out of) the 6.
