Bozak concert grand speakers

I would just list them on Ebay as a cash-and-carry only item and you will find a buyer.  There are a lot of people who love those vintage speakers.  I sold my father's EV Royal 400 on Ebay in 1 day, whereas they sat here for a month without a bite.  I have no idea of how much they are worth, but you can figure that out.  Good luck.  I'm old enough to remember them, but I never actually heard a pair.  

@mlolaird- it is possible that your father added a super tweeter. I am not familiar with the term "crystal bar" in audio, but there were piezo electric tweeters, electrostatic ones and others. Can you get more information from a label on the back? 

It was a popular tweak back in the day, to fill up bags of sand and put them inside some speaker cabinets for additional mass and rigidity. And yes, I remember a few manufacturers having " bins " as part of the design for adding sand / lead shot ( not Bozak ). Enjoy ! MrD.

There are two tweeters sitting on top of both speakers.

There are also four small speakers at the ceiling on four corners of the music room.  He has McIntosh amps and preamps too.  Oh what to do!!
