I am in the process of just replacing the center speaker with an Optimus (Radio Shack) 3-speaker enclosure that was given to me by a friend. Initial testing sounded great and really provided lots of depth to the mid range sounds. The enclosure is fairly lightweight and sturdy. I looking to possibly mount the front and rear speakers on this cabinet and placing the single unit on one of my heavy-duty mic stand poles. When it's done I'll post photos and test results.

As for replacing all 5 speakers, one of the PSR-tutorial members did this some time ago and reported excellent results.

Good luck,

Gary
