I bopped on over to GC today, and ended up listening to some Mackie 1530s they had set up. I popped in my blues collection and ... was blown away. Clean, full sound at very high SPL. Plenty of bottom, too. I've been thinking about replacing our QSC/JBL amp and speaker system with these actives. Good idea. Soolnzai get some cash, it's a done deal. The speakers have a 15, a 6 and a horn in each, with a 300-watt amp to drive the 15, and two 100-watt amps, one each for the mid and horn. You gotta hear these things.
