Hello everyone, Here's what happen, i was moving my receiver & the cable of the subwoofer got unplugged. I thought I turned both receiver & subwoofer off....i plugged the subwoofer cable back into the subwoofer & then a loud sound came on. Now my subwoofer will not power up. I'm assuming this is a blown subwoofer? Is there a way to fix this? thanks in advance.
