Thanks for taking the time! I have a pair of FBT Maxx 2A's that I got about 7 years ago, and they deliver great sound. They weigh about 28lbs each. They deliver bass down to 50hz.
As you know, I do the senior circuit in the Chicago area. I almost never get volume complaints even though I play at a decent volume. I think that attests to the high quality sound, that there isn't any listener fatigue.
I'm very curious about the Bose and some of the other systems out there, but I already own this one. It's never given me a problem in the last 3000 + gigs that I've done with them.
I wouldn't want to try some of these smaller systems because I wouldn't want to lose the bass.
Good luck choosing!
