[QUOTE="Rob Spence, post: 209298, member: 80"] At a gig a few weeks ago, one of my four EV QRX212s had a high mid distortion. Changing amp channels did not change it nor (on the wild possibility of venue interaction) swapping cab with adjacent cab. Other than the odd distortion, the cabinet seemed to perform ok. So, today I opened up the cabinet. Removed grill. Inspection showed the horn somewhat distorted at some of the mounting bolts. Since the gasket is pretty thin, perhaps an air leak interaction? I pulled out the horn (after marking the up location) for further inspection. I found that I could easily take up about a full turn on each of the four bolts that attach the DH7 driver to the horn. Ideas to try while it is open? Suggestions? Rob T, anything to add or clarify? [/QUOTE]
