Thanks Rocket, yes I have finished the exterior cabinets. I believe the woofers are original but the tweeters were removed by a previous owner that attempted to "customize" them. I am looking to get them back to when Bob made them, or possibly better with his upgraded parts.
I will try and get in touch with ted_b and see what information he can recall. Thanks for the lead. Im just hoping Bob gets back to me and we can complete these magnificent speakers.
