Naive question. Have a Martin Logan Cinema TM (CLS electrostatic). It seems to work just as well when not plugged in. I'm trying to tell from the manual if it is a hybrid and if the electrostatic portion may be shot. Can someone help me out?
The power is needed to drive the woofers. The panels derive their power from the speaker cables.
I'm pretty sure it's the exact opposite, at least it was on my Ascents from a few years ago. AC power for the panels Cone woofers don't need external power source
The power is needed to drive the woofers. The panels derive their power from the speaker cables. Same with my Summit. If you play something with a lower frequency than speech, you should notice a difference.
I own Martin Logan SL3s. I have no experience with the Cinema TM. But looking at a picture I can see the pannel. I assume you have a single center channel speaker. There should be a noticeable difference when the speaker is plugged in. Have you tried listening with the other speakers turned off to see if you hear a difference? It is possible the pannel is blown but I would think more likely it might just be a fuse. Also make sure that the power cord is tight.
