⭕ RARE matched pair of RCA MI-1443 field coil horn drivers vintage western electric era. These are identical to the MI-1428B. The only difference is the field coil voltage.

There is some wear to the paint. Both drivers are tested and working beautifully. Original phenolic diaphragms are perfect in both. I powered them up and played them, they are both working properly. DCR of field and voice coils is very close. Also the serial numbers are very close. Comes with 30 day return policy if unhappy with the purchase. Shipping or local collection.
