1 Pair of Atlas PD 5 VH Alnico compression drivers with horns. The horns are identical to the Klipsch model K700 but where made for Beta Sound. One driver has a black rear cap the other a grey back cap but same drivers. Earlier models made in Parsippany N.J. These units have spring loaded binding posts not the solder ones. One unit has a small push mark in the screen but does affect performance.
