My QSC K10 was stolen a couple nights ago and I'm looking for a lower price replacement. I've been curious about the ZLX's for awhile and the price is right, but the last time I tried budget speakers for my keyboards (Behringer, Tapco Thump, etc.), I found that they sounded great at room volume but broke up when pushed to higher club volumes. Will the ZLX-12P hold up at max or near-max volume? I'll be playing a pretty full range of keyboard patches, and had to run my QSC at 75% to keep up with the rest of the group's stage volume.
