Bozak concert grand speakers

@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!!

OP

with the MAC gear, many many will be interested 
at least call Andy at Audio Classics to get some ideas on value before you give this treasure away
ebay is always an option but use caution 

audio classics is in essentially same town as McIntosh of old and the Factory, a long time Mac dealer
can also provide correct shipping boxes

while I am a long term client, I have no financial dog in this fight

unless you have an MC240 or two....

then send me a PM
