I suggest that you check the cable with an ohm meter. If you're lucky, it'll just be a loose wire strand at one of the ends.
If it's an in-wall issue, there are wireless adapters. The issue is that you'd need an amplifier for that speaker; the wireless adapters transmit signals, not power.
There's one cheapie that is both: https://www.bestbuy.com/site/rocketf...?skuId=8275528
(It's actually a stereo device. Speaker-level inputs. 30W/channel into 4 ohms, presumably half that into 8 ohms.)
The more I look, the less hard re-running, if I determine that I need to, will be.
I'm going to play with it some this week, starting with checking out that wire and ohming it out. If the cable seems to check out ok as far as a short goes, I'm going to crimp off the ends clean and reattach my banana plugs. on both ends. I know anything is possible, and I'm certainly not infallible, but it seems awfully strange that I'd put banana plugs on all those ends, without a hitch, and somehow mess up on just that one. Still anything is possible.
Failing finding evidence of a short or a problem with my handiwork, I'm going to remove the wall boxes, pull the wires back, then drill down through the box hole, through the floor, into the crawl space, then run a new wire through there. Luckily, there's a second subwoofer connection ran to a box directly under the one for the speaker in question, so it should be pretty easy to get through the floor from there, then fish the new cable up to the speaker box. That's my last resort though.
I'm not going to have five good runs, five good speakers hooked up correctly, then mess with some half-baked wireless mess for that one speaker!
I'll post here what I find. Wish me luck!
