Cool website. I was suckered into these peices of junk in college. Over the next ten years I started learning about hifi and modified those babies probably 15 times...
Lined the insides with 3/4" plywood to reduce cabinet vibration.
Added fiberglass batting.
Bought new woofers.
Added awesome tweeters - Heil AMTs. Very high end in its day.
Threw away the midrange completely and covered up the hole.
They still sounded pretty crappy.
Sold 'em at a garage sale for $30.
Settled for Snell K-2s.
