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!

Make certain that both sets of speaker cable lugs are tight on the "jumper" if you are not bi-wiring.

That's all I got.

you will need to fix the crossover to fix the problem. Open it up and find out where the problem is. Its not rocket science

True. It could be that something has come unsoldered, or you might find evidence of a disconnection on the crossover board itself. Be bold and see what you can find.

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.

Good...

Glad it was a simple fix (without tearing apart the crossover and/or drilling holes in the speakers cabinets to "tune" them-;).

Experienced the same problem with a pair of Castle Isis speakers a long time ago (while experimenting with bi-wiring/jumpers et cetera) thus the suggestion.

Interesting power amp, which I've read easily betters their old 100.2 (that I liked a lot) and I'm a diehard tube fan.
