I took my 20 year old kenwood tower speakers and ripped the guts out and the front baffle. I have braced it up and sealed it. This was a cheaply made box if I've ever seen one. Anyway, im getting all the speaks from PE and dayton 1 1/8" silk dome tweeter, a vifa midrange, and a peerless woofer for a three way system. Parts should be in this weekend. I'll let you know how it all works out. I sure do have the speaker building bug.
