Hi,
Like Gary, I'm growing long in the tooth, and I've tried just about all of the systems alluded to on the forum - plus. I went back to the Barbetta Sona 31 for small gigs and still use the Bose L1+B1 for larger venues. I play regularly in a small restaurant - seats 120 - and the Barbetta seems adequate, certainly not the same sound quality as the Bose, but it does very nicely. I have two Barbettas but only use one for the restaurant gigs and have it only about 3" off the floor. The tables right in front of me get an earful but no complaints so far.
Ciao,
Jerry
