As talked about in the craigslist find post a few below, I found ended up buying the pair, with the 60 inch ribbon upgrade. I got them home, listening to them, sounding great, turned it on up but not nearly all the way up, all of a sudden it drops out, all Ive got is extremely low sound from the speakers, mostly the bottom end. The fuses in the speakers are 250volt Slow Blows, Is it possible they went partially? Never dealt with slow blow fuses before. Anyone have any other thoughts on what to try and look at?
