I've been using the Tuba 24's & DR250's for PA now for about 6 months. I've been extremely pleased with their performance and we play a wide variety of stuff much on the "heavy" side like Van Halen, Ozzy, etc. I just upgraded the DR's with Eminence 2510's, and the T24's with HL10C's. It's amazing how much sound four 10" speakers can produce. I've heard other similar "four box" PA's with JBL, EAW etc. and none can touch these especially in the low end. The 2510's made a noticable improvement in the low end of the DR's which were previously loaded with Carvin PS10's. This past weekend I ran the PA using an aux sub, with my new Behringer DCX2496, crossing over at 100hz. This combined with the new speakers made the system extremely clean and responsive, the best it's ever sounded. My next project will be wedgehorn 10's, for a total BFD PA system.
