Someone help identify these electrostatic speakers?

[Audiokingman]

Got these electrostatic speakers at an estate from a woman whose husband died recently.
I do not see any logo identifying the brand or model. Only a serial number.

Also, the electronics/speaker terminal section in the rear was missing from both speakers. She said she does
not know what happened to them.
I am suspecting these are Martin Logan CLS speakers.....can anyone help confirm?

CLS appears to be correct. But getting the replacement electronics may be difficult (not to mention expensive).

Those are very cool! Try contacting ML, see if they have the electronics.

It's possible that the original owner purchased replacement panels and then sold the original set with the electronics. ML panels do age and need replacement sometimes. It's difficult to tell from your pictures if the panels can be easily separated from the frames, or if they're not designed to be removed.

ETA: or possible they're the original panels after an upgrade.

Did you leave your number with her so she can call you if she finds a Martin Logan box or a pair of "electronics thingies" ?

From the serial number decoder on another site, these are Martin Logan CLS 2 series built in May 1989, probably original panels. Panels are user replaceable, they pop out of the oak frames with some pressure applied to the rear middle of the panel. It will be a challenge to find replacement electronics for these, here’s hoping previous owner can find them for you. The panels shown are pretty old and replacement panels are still available from ML I believe but are pricey.

Yes I did and I'm keeping my fingers crossed but I'm not banking on it.

If I can't find the electronics at a reasonable cost somewhere out there, I will probably end up putting them for sale to someone who may have have the electronics but doesn't have panels or whose panels are defective or are in bad condition in comparison.
The wood on these things are beautiful and of high quality.
