No one thing is perfect for all conditions, including the Bose, but it comes close for me in most instances.
It CAN be a problem if you want to restrict the sound to a smaller area. At the restaurant where I work most, there are other rooms in which you can hear my sound when I crank it up a little. There is one small area toward the left and back of the room in which I play that the sound is actually louder than it is on the dance floor directly in front of me. I finally figured out that it was because of wall surfaces, mirrors, windows, etc. Not a big problem, but occasionally a party will sit back there because traditional wisdom tells them it will be quieter. That's not the case with the Bose. So far there has been nothing that I couldn't easily deal with though.
I still have occasional guests who don't want to sit near the band stand "because it's too loud", even though they haven't been seated. Their experience with traditional bands have understandably caused this. Now, the waiters are telling them to try it and if it's too loud we'll move you. They never ask to be moved.
