Help troubleshooting: 1 speaker is playing significantly lower


Greetings all-

So I connected my Sonus Faber Concertinos and for no apparent reason the left speaker is playing at a significantly lower volume than the right (with no distortion) Fyi- I never drive them hard and I meticulously power down my rig when swapping speakers. I rebooted the rig and same issue. I then swapped the SF with my Vienna Acoustic Hyden’s and they played perfectly. 
I haven’t had time for further troubleshooting, I’m curious as to what possibly could be the issue. Also, if the speaker is shot, where does one turn to for repairing a SF vintage speaker? 

thanks in advance!

It’s perhaps overkill for what I need but I do love it, no complaints whatsoever.

Rookie move on my part, I should be spot checking every time I speaker swap. Keeping my fingers crossed that everything is 100%

DUDE!!! I owe you!! I got these heavy duty jumpers on the Farber’s..two of the spades were touching! They must have moved during my speaker swap-outs. I repositioned and cinched them down, gassed up the system and BINGO! Problem solved! Can’t tell you guys how relieved I am...thank you all for your help.
So i put the Sonus Farbers back into the system and I reversed the speaker cables as you guys recommended. Result was the left speaker was still very low. Now being that my secondary speakers (VA Haydn’s) play perfectly fine, my components are obviously not the issue. 
I don’t know much of anything about speaker builds, could the crossover have crapped out?
