One speaker is louder than the other


I just got a pair of Celestion SL6si speakers from ebay. they sound wonderful, however one speaker is not as loud as the other. I need to adjust the gain on one speaker 2 clicks on my volume control

what would cause this? a Capacitor or resistor?

TIA

switch loudspeakers from left to right see if problems follows loudspeaker if so its in the speaker not the system.
I think I have found the problem. the surrounds on both speakers are cracking and is worse on the right side. Plan to get them repaired this week.

That will do it. Let us know what happens after the repair.
