Electromotion ESL channel imbalance

Hello, I have a 2 year old pair of Martin Logan Electromotion ESL speakers that I bought second hand. There is a channel imbalance where one speaker is louder than the other and vocals are skewed toward the right. I thought it could be my amp but I swapped the speaker to the other side and the gain difference follows the speaker. I am not sure what I need to do. Seems unlikely to be the panel since the speaker is two years old. Is there a way to troubleshoot this problem to determine if it could be a crossover/power issue. I realize they are not under warranty because they are used.

Thanks,
Tony

Hola. Channel imbalance could be several things. The best advise is, contact ML service dept. Report their serial no and explain to them what you had done. It could be the PSU (power supply unit) or a bad stat panel. You will be in good hands! They will guide to track the problem and how to fix it.
