I have a pair of these speakers. They are in wonderful condition and sound great. They weigh in at 44 lbs apiece. Each are comprised of a 15 inch air- suspension woofer and a 1 inch horn tweeter. Made in USA. Anyone know any history about these speakers and if they are worth anything? I would assume they are from the early 70's. This is what they look like http://photobucket.com/albums/y229/jlindsey86/?action=view¤t=Speaker.jpg http://photobucket.com/albums/y229/jlindsey86/?action=view¤t=SpeakerGrillOff.jpg
