I personally use the Bose L1 system, mainly they are extremely easy to transport, and it seems no matter where I play they always give me the same hi-fi sound.

My main complaint of the system is basically what UD said, they seem to not have that punch or in your face sound of horn driven systems.

I have 4 double bass systems for when I do full band set-ups. I had some sit-in musicians who are used to the over the top multiple speaker array for the dance club sound. They complained saying " the sound is not loud enough " . the funny part was that this person from the band was the only complaint, we were constantly getting praises from people saying, " wow the music sounded fantastic, and after 4 hours I don't have a headache and I was still able to carry on a conversation at my table. you guys were a pleasure, never once did we have to ask you to lower the volume."

this is Frank math

it only takes 1 valid complaint to cancel 10 valid praises
