I own a Logitech Z3 speaker set, which uses a proprietary mini-DIN connector between the control/volume module and the subwoofer. Over the years this connection has gotten more and more loose, causing one of the left or right speakers to become silent, which I would correct by slightly moving the connector around until all the pins got connected again, and taping the connector into place. This temporary fix has become untenable, however, and I am wondering if I can permanently fix the loose connector in place, or maybe cut the connector entirely and hardwire the subwoofer connection.

I opened up the back panel where the female DIN connector is, but could not proceed further, since the panel itself seems to be wired with a short wire to the subwoofer speaker inside the speaker box, and I am hesitant to force open the front of the subwoofer, since there are no visible screws / tabs to do so.

Is there any way to either fix the DIN connector itself so that it fits properly again? Alternatively, can I cut the male DIN part out and somehow insert and solder each wire into the female DIN part?

The speakers are in really good shape, and I would hate to throw them away just because of this loose connector. Thanks!
