I managed to smoke two fine amps on my L77 spaekers. I believe the crossover in the left channel was to blame. The tweeters and the midrange woofers all read 4.5 to 5 ohms DC resistance. Don't know how else to test them, but the capacitors are cracked and dried out and it may be shorted somewhere. Any ideas where to get replacement parts?
Thanks, Tom

Curious if they are the culprit, or whether another issue has occurred.

L77's are parted out on eBay regularly. Whole crossover modules are LX4 perhaps
with a -1 or -2 suffix? check yours...

I find it hard to believe both speakers did the same thing..???
