hi I was wondering if anyone uses PA speakers for their bass amplification. I found a JBL MR838 which does 38hz-20 khz, it has an 18" low frequency transducer , a 10" cone midrange and a titanium compression driver on a a flat biradial horn. It can handle 250 watts of power at 100db sensitivty . Can this just be hooked up to any bass amp and played ? Will it sound good? Do you think it will have sufficent volume and punch for bar gigs?
