Hello everyone. First time poster. I am pretty active over at AudioKarma where I go by the same handle, but I noticed quite a few of you have "Polk Guru" titles, and there doesnt seem to be any Polk Gurus at AK.
Here is my question:
Today I noticed that two of the 4" drivers in one of my Polk 9a's (1976ish) aren't working. I tried unscrewing the piezo, the offending 4", the passive radiator, etc and just could not get inside the box to check the wiring, crossover, or any of that stuff. There was a thick grey goo cementing the speakers to the box. I was afraid to damage the speakers by applying brute force.
Can anyone here please help me? Is there a trick to this? I would hate to have to butcher these vintage rarities simply because two of the four 4" drivers in it arent working. It is probably a simple fix like a loose wire or corroded solder point.
Thanks everyone. Happy Holidays.
