Well I lent my M-Audio Bx5's to my brother for his birthday party do. They were inside a bedroom which overlooked the party area...so noone touched them or anything. Anyway, they were rigged up to a PC with presonus firebox as soundcard....everything maxed to 10 at every stage for 6 hours.
When I reset them up back at my place there just weren't any highs to speak of. The tweeters were cactus. So, the monitors are in getting fixed at them moment. Never again.
