Any suggestions on diagnosing problems with a Sub-10?
My receiver died like 2 years ago, and due to the pandemic and chip shortages, I couldn't replace it until last week. I got everything hooked up, and was surprised to find the sub not working. When I ran it through the new receiver's setup/calibration, the sub would make *some* noise when the system was testing that channel, but it was never enough for the setup mic to pick it up. I picked up an R-100SW to test with, and it works just fine, so the problem is definitely the old sub, I just have no idea what the actual problem might be or whether or not it can be fixed (or if replacement parts are even available).
I don't *need* the Sub-10 anymore, but it seems like a waste to toss it if I can get it repaired and maybe return the R-100SW instead.
