I just bought an used EPIC80-500 V2 system from a guy couple days ago. After I hooked up with my receiver I immediately noticed that no sound from both tweeters on one of M80 speakers
(the other speaker was OK).
I gave the speaker a kick, the tweeters worked. However after while it stopped again. another kick will make it work again.
This was night so I kept the level pretty low.
The next day I tried to crank up the sound to check whether tweeters sound normal, to my surprise it working flawlessly. I kept play loud music for about 1 hour, then turn the level down (not too low though ). The tweeters still work fine.
Have you guys seen this kind of problem ? should I replace the tweeters ?
