Do you cover your towers?

Like chicken soup"It couldn't hurt"I think protecting ones gear keeps it attractive and the resale value's will be higher.

Undoubtably speakers that have been blanket covered will give a warmer sound.

That explains what I've been hearing! I thought it was the cables I just bought. doh! I wonder if an electric blanket would help even more?

I guess it would make some sense if you were away, but when at home, If I were you, I would consider getting grills as protection for your speaker drivers and for aesthetic reasons also. Having blankets draped over my speakers would make for a less than desirable appearance in my den and that would piss my wife off, and honestly, I wouldn't like it either.
