So I'll start off with saying that I have this system. My son, poor boy, put a toy through the hole in the sub woofer, I wasn't home when my wife removed it, but after that, the whole system started producing distortions at all volumes and frequencies. I attached an old Sony receiver I had to see if it was the receiver and the sound seemed clear, however it is an old receiver. How should I proceed? I know very little about sound systems and am curious whether I should ignore the sunk cost fallacy and get a whole new system? Try to get the receiver repaired? Replace the receiver? I can probably swing around 200 bucks.
