SquareTrade © AP6.0This listing is for a Pair of McMurdo Silver Super-Giant 18" Electro-Dynamic/Field-Coil Speaker Made by Jensen possibly model M18 or L18 from Western Electric Era. I have not been able to test the speakers for sound but was able to get the DCR readings for bothe the field coils and voice coils. The first speaker has 3 field coil plug readings pictured and the voice coild reading seemed to fluctuate so I took 3 pictures of the different readings, I don't know if it may have been corrosion on the leads from the voice coil. I also used the sound continuity feature on the ohm meter and it sounded good and continuous. The DCR readings for the second speaker were voice at 5.4 ohms and 2 readings from the field coil plug are as pictured.

Cosmetically the speakers seems to be in pretty good shape but do have some repairs to the cone as you can see in the pictures and close-ups of the repairs.

Due to age and not being tested the speaker is being sold AS IS for parts or repair.

The buyer pays for shipping and handling/packing, there is a small international paperwork preparation fee of $50 for each item being shipped outside of the USA.
