Hi Juddboz,
When did you put them back into service together?
Had you made any changes at all to your setup, like connecting or disconnecting speaker wires or new interconnects? Could your speakers (one of them) be hooked up out of phase or opposite of the normal connections?
Failing that, try turning the two midrange and tweeter controls about 10 times each on each speaker before resetting them, that would help clean the contacts out. Also, double check your speaker connections at the speakers and the amp, be sure they are clean all around. If that doesn't work, check or change the speaker wire for some new stuff, just to be sure it hasn't oxidized.
Otherwise, now it gets a little harder. Pull the woofers and examine the wiring, ensuring it is correctly connected to the woofer in the correct color code (see JBL tech reference a few posts up). Also, examine the crossover for any signs of injury, scorching or damage.
Then transfer the woofers to the other speaker and reinstall and retest. See if the problem follows the woofer or the speaker. If this doesn't change things, do the same with the midrange. Those are the only ones with any significant bass output.
I would also double check all setting in the amp. Try a mono source or feed the exact same signal into both left and right channels - you should get a very stable center image with all controls at the central position.
