Pair of vintage RCA MI-9584-A compression drivers.  Rated at 15 ohms.  DCR measurements are 14.5 ohms for both drivers

1.5" throat, all bolts present.  Extremely rare items!  I’ve had these for many years and have decided I don’t have the time/energy to build a pair of horn speakers with them.

These drivers date from the immediate post war era and are in perfect working order.  Weighing in at 17.5 pounds each.  Serial numbers are 2973 & 2983.

Price is for the pair.
