>> If you need to plug the port, then put a sock inside it.

I thought that plugging a speaker that wasn't designed to be plugged would negatively affect the sound. But heck, now that you mention it I'll try it with my M22s and see what happens.

Regardless, that's hysterical! And I'm letting you know now that I'm stealing it.
