I have an oppurtunity to purchase some older Altec's but we don't know what model they are. The guy say's the cabinet's have 2 12" woofers and 1 8" horn. Anyone know the model of these? He also say's they are for p.a. use .Are they worth $300.00. I am trying to get driver model's from this guy. Have to wait and see what he writes back. Sorry no pictures. Thanks!
