Electrostatic speakers

I picked up a pair of Electrostatic Research Vista by Sunrise Audio;. Hooked them up to test them and both work. One sounds significantly louder them the other with balance set evenly. Does anyone have any ideas as to why? I am running them with a pioneer receiver just to test them. They are at my office have not brought them home yet. I plan the run them with two NAD 2200 amps, biamped. 
thanks

Not unusual as electrostats age and one panel degrades more than the other.

I couldn’t find any information on these from an, admittedly short, Google search. 
 

Do they have bias adjustment? Check the back of the speaker for some sort of pot that is adjustable.

i did try to switch the channels. it made no difference. I've checked the fuses also. funny thing. i did not think the woofer were powered, but the on/off switch dose not seem to make a difference in sound on ether speaker. i was going to try swooping the panel next. When you say they degrade is it the coating on the firm/membrane? i wouldn't think the transformer in these would degrade.

thanks

The only information i could find on them was a review from Vault.
