From what i understand, JBl made those speakers as a Keyboard speakers. How would this be for Bass? Midrange drivers are JBL 2118J . Bass drivers are .JBL 2032H 15" .Don't know about the tweeters, my JBL 4628b 'Cabaret' cabinets are missing the original JBL "Baby Butt Cheek(?)" tweeters, but they do make aftermarket replacements. I am running old Peavey Tube Stereo 120-120 Power Amp with a Peavey Bass tube /solid state preamp. Just a six string player, and asking for a fiend.
