Martin Logan Motion 30 - Bad Woofer?


New Member
Apr 18, 2019
I recently took a chance and picked up a used Martin Logan Motion 30 center channel speaker. I noticed one of the two woofers in the speaker is producing significantly more volume than the other. There is are only two inputs terminals on the speaker: pos and neg. Am I dealing with a problem here? I have a small window of opportunity to return the used item.

Reading other threads I have seen where some center channel speakers use two different crossover frequencies for the woofers, essentially using one woofer for bass and the other identical woofer for mid range frequencies. I can't find any documentation that would suggest this is the case here.

Any thoughts or advice you have is appreciated!
