Aw c'mon, rollergoth in the last scene was a hoot. The whole episode has so much genius crammed into it my head almost sploded.

I was going to suggest replacing your speakers with those from the public library, but they probably don't have any.

If it was me I'd probably unplug them, smooth out the cables, run the cables so they're not near any power cables, and plug 'em in again, all of which would prove futile and result in me having to buy new speakers. One way to check if the speakers really do need inhuming is to plug them into the EL's machine and see if they still misbehave.
