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!

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.

you could damage your amp doing that.

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%
