acousticraft bosak speakers??

i have a set of cabinets that are labled acousticraft they look like old end tables. i opened them up and they have a 12'' bosak that is mounted to a frame that makes it fit a 15'' whole. the drivers also have some kind of bridge across the cone where 2 2.5 inch speakers are mounted these are the mid and high. are these worth anything at all or has anyone heard of them. the sound pretty decent concidering the obvious age.

Bozak was a well respected speaker manufacturer and the speaker you describe would be a coaxial driver. The smaller driver mounted mounted in the center is for the mids and highs. You had said Bosak but I was wondering if that might be a typo? If in fact the drivers are Bozak I am sure you could find much information from vintage audio sites. Here is a link to Rudy Bozak.
