it’s complicated
As long as whatever is on the other end doesn’t reproduce anything at 60Hz or does so with a lot of loss and there are no heavy vibrations closeby (such as the speakers themselves), it should be fine.
Why 60 Hz? Doesn’t the frequency response of this antenna depend on the length/shape?
It’s the one part of the radio spectrum that’s also in the hearing range hence induced currents from it can be heard in an analog audio system and which would have a pretty decent amount of energy inside a building because it’s being emitted pretty much all around by the mains power wires.
That said, you’re right that depending on the length and shape those wires might not form a very good antenna for that frequency. Independently of that, I doubt there’s enough energy around to directly affect speakers, but it might be enough if that wire goes to an amplifier which in turn powers the speakes.
That said, I’m from Digital Systems rather than Telecomms or Audio so take what I say on this as a semi-informed guess.
It does have a decent loop area in between the signal and return path and any flux passing through it will induce noise. This area is too small for 60 Hz, but there’s a lot of microwave crap that would get picked up. If there isn’t a low-pass analog filter before the next silicon junction then this RF EMI will get rectified down. If it’s a sufficiently bad situation then you’ll hear it. That’s why you can hear garbage when you put your phone right next to crappy computer speakers.
I’m not even mad, that’s clean!

For years, I took the wrong lesson from that Monster Cable experiment and only listened to my music through alligator-clipped coat hangers.
You can order an adapter for like a dollar on multiple websites. I mean yeah, there’s no Radio Shack anymore, but this seems unnecessary.
You don’t always have the luxury of time though. I work in entertainment, and I’ve definitely scrapped adapters together in a pinch. When you have a show starting in 15 minutes and a musician rolls up with some bespoke gear with weird connections, your only real choice is to bodge something together and make it work.
Nothing quite like seeing five adapters chained together, to go from stereo RCA to TRS 1/8” to TRS 1/4” to dual TS 1/4”, to XLR… All because you didn’t have a direct box that went straight from RCA to XLR, because another musician walked off with it after their show wrapped up at 2AM last night.
Apparently there is at least one RadioShack open. I saw a dude post a video on YouTube about one he found in Wyoming.
There’s one in Afton, Wy if that’s what you’re talking about. It has a giant “We Are Open!” sign that reminds me of Clerks
I think this is more for that time you’re at a gig and realise you’re missing the adapter.
… And you just happen to have a piece of like 12 or 14 AWG copper wire on hand?
That does make sense, although it would be weird to go to a gig and not have a 1/4" to RCA adapter but happen to have large-gauge copper wire.
