I am sorry to say that, while over the years I have hears some of Martin Logan's speakers, that is a model I have never heard of. I also don't know about electrostatics way & time of deterioration. But I have a number of "vintage" speakers and would like to offer some advice: If there is any possible way to arrange to listen to these speakers, do so. If that could be done & they sound OK (no obvious big flaws), then I would likely buy them. I have always been impressed with Martin Logan electrostatics that I have heard. I do know that location of how you have the speaker setup in the room will likely be further away from the wall than with "box" speakers. This is something you can research and will likely require moving them around the room some until you are happy with the sound. You really never know how speakers sound until they are in YOUR room. I did find this review from 2014:

Best bang for the buck
First of all. The specs are true and it really does reach 28 hz. I don,t need to increase the bass or treble and they sound just as good. A sunfire amplifier 325 watt is perfect. Driven by nakamich av10 harmonic time alignment receiver. Although the off axis response is not that great i feel if placed properly the back reflections can be used to increase it with a highly reflective wall. The bass is tight and for a 10 inch acoustic suspension woofer to go down to 28 hz sealed enclosure, thats a quite an achivement. Bought them used 2004 thus they are now 10 years older and still good. God bless Martin Logan for 200 years.
They sold for $1995 when they came out in 1989 & for $2995 toward the end of the production run. On HifiShark there are several for sale, some of them for more than the original cost.
Amplification can be a problem: you will need something that is not necessarily high wattage (100 should do) but high current, able to deal with 4 ohm (better yet 2 ohm loads) without issues. I am fortunate in that regard, as my triplet NAD 2200's (1 of witch Amir reviewed)can pull off 2 ohm loads. May Your Ears be Blessed with wonderful sound.
