I've got a pair of Venturi (BIC America) V62's that were purchased about 10 years ago. I don't normally use these speakers, but my roomates blew my nice ones and I had to pull these out of the closet for a party. Long story short, I have them hooked up to my Rotel 1095 (200 watts by 5 channels) and was running my HK 235 around -6 on the dial (and it's been calibrated to reference at 0). I did not notice any audible distortion to indicate that the speakers were being driven too hard, but at some point towards the end of the night, after 3-4 hours of use on varying rock & hip hop the midranges totally crapped out and stopped working. I took out the driver yesterday but couldn't see any visible damage, but my guess is that the mids just got fried. The speakers are rated up to 150 watts, but it was my rough understanding that as long as I wasn't hearing audible distortion, they should've been ok. I'd appreciate any suggestions to make sure this doesn't happen again (and hopefully I get my Joseph Audios back soon). Thanks.
