I use two Barbetta sona 32 powered speakers. they only weigh 36 lbs each and they can blow the walls down.I don,t know how Barbetta does it ,but the first night I used them my wife and the club owner ( ALSO A MUSICIAN) told me they were as clear at the back of the room as at the stage.If you are drowned out using these babies then the only thing you can do is shoot the other band members and the sound man.
