Hi musician friends, I FBT jolly 10 15ba active 350w, 15, and a pair of jolly 12r passive 250w amp that operates with a phonic max 860, I must say that it is a very good quite old brand pluttmconnue on reliability in time I can not say, but it turns DJ for two years without problems, performance is impressive is lacking some medium but sounds tr s HIFI for sound enclosure, I also HK dart, very good product 375W, 12, I have not had time to compare.
