Western Electric 755A vs Altec 755A 8" full range drivers


Recommended Posts

Is there anyone can tell Us for Sure what the original Western Electric 755A driver was rated at? 4 Ohms or 8 Ohms? Also the Altec 755A that was used in the AR-1 speakers to mate with the 4 Ohms Alnico V magnet woofer, are they rated at 4 Ohms or 8 Ohms?

If you are Lucky enough to own the original Western Electric 755A unit and measure the DC resistence, very likely you will get 6+ Ohms. For all the one who are Rich enough to purchase the AR-1 speakers and gutted out the Altec 755A drivers for the pride of ownership, the DC resistence normally read below 2.8 Ohms? I had heard of some units that measured as low as 1.3 Ohms.

Any knowledgable answers will be appreciated.
