ERA Pair (2) Rare Poly-Planar P-20 Super Thin Wafer/Panel Speakers 4-way 25 Watt 8 Ohm Titanium Driver Magna 1970 - 1960s speaker cloth and frame
Our users rate Reverb
Both drivers tested from 40 Hz to 20kHz - sound GREAT. DC resistance is 7.2 Ohms on the box I opened and 6.9 Ohms on the box I've left closed.
These AMAZING and weird drivers have been mounted in homemade boxes since the 1970s. They were designed to hang on the wall like pictures. The boxes are about 21" wide by 20" high, and 3" thick. The drivers weigh almost nothing, but I will leave it to you to remove them from these cases to prevent damage. Wooden boxes are each about 5 lbs.
Drivers are 300 x 355 x 35 mm / 11.8 x 14 x 1.4 inch. "poly-planar" loudspeaker. Impedance 8 ohms. Frequency range 40 Hz - 20 kHz. The membrane is made of styrofoam, mounted in a rigid plastic frame.
There was a discussion about these a few years ago for your reference:
