Can anyone kindly help me with my problem, which is that one of my Spectra 1100's has developed a nasty screetchy, distortion with certain material, most noticeable on female vocals played at loud levels?
I have owned these speakers from new (1989 I think). I did have problems a few years back, when bi-amping, one channel of the amp driving the woofers blew and its corresponding woofer was fried. I replaced the woofers after some kind help from Parts Express with Dayton Audio RSS210HF-4 which I realize may not be an exact copy but to my ears is a big improvement.
I returned to using only one amp for about two years and all was fine but when I attempted to bi-amp again, the same channel started to over heat. I then tried bi-amping vertically with each amp driving both woofer and ESL, one for left speaker and one for right, and that worked fine. But the side that blew is the one that is now distorting.
