I upgraded my computer sound system to a Z-680 5.1 system this weekend. I’m looking at my old Klipsch 4.1’s and trying to figure out a fair price to sell them. They’re about 4 years old, but they still sound good, except for the subwoofer. I’ve been playing around with the sub by itself and it sounds more distorted than I remember it being. At normal volumes it’s okay, but crank it up and it sounds like there’s something loose vibrating in there. It’s not a clean sound at all.
So, the question is: Is there any way to “fix” a subwoofer?
