OT: Wireless rear speaker adapters for 5.1 systems

So use the thin wiring on the walls (it's about as bulky as masking tape) then paper/decorate over it.

It wouldn't pass SWMBAs aesthetic review, and a tech review might think it a bit dodgy too: 16 gauge, 17m (length of room + width of room + up/down round a doorway) so 34m round trip ... about half an ohm. The cost is non-trivial for that sort of length. Thanks, but no thanks.

I've suspected you don't understand the product I'm talking about. It's a laminate and intended for mains wiring, but could also do speakers. Should be invisible even if 'only' painted over.

Mains can have quite a bit of resistance before its an issue, Speakers should not have very much at all.

OK, a link would be useful

It's not sold by Amazon, it's on Marketplace, yes OK you can return stuff, a quarter of reviews give it 3 stars or fewer.

Linky?

Well read them and see why.

Its is fundamentally something that will work, or it wont.

I can see it failing over a long distance in a wifi crowded environment

But across a room it should be OK

Read the spec of the product in question, then come back.

No, that appears to be something different.

But scene with something like a jet fighter flying overhead from behind might lose much of the impact if you see it come into short, and disappear into the distance and hear it after it has gone!

I had a pre-recorded VHS tape like that - most odd when watching scenes with car pass the screen left to right and their sound going the other way.

My Thomson headphones use 863 MHz and have no latency.

Especially with modern "object oriented" soundscape placement technologies like Dolby Atmos. The soundstage designer no longer just mixes the audio down to 5.1 surround sound. Instead they place each audio component into 3D soundstage space, and then it is left to the playback decoder to mix that down to whatever channels/speakers the reproduction equipment has available.

So the rear effects can be called upon to do more of the "placement" of audio anywhere in the room, not just what is notionally "behind" the listener. So a sound that is directly above the listener could be sent to actual ceiling speakers if fitted, or the decoder might use a virtualised ceiling speaker created by mixing the sound into the output of the front and rear and side speakers. If half of that turns up "late" it is going to be noticeable.

I expect most will simply reproduce a "line level" signal at the far end

- so not suitable for driving speakers directly without an additional amp (either separate or built in)

Please can you post a LINK to whatever you're discussing. The concept of thin laminate, stuck to the wall and (apparently) intended to carry mains, is surprising - the required insulation would stop it from being described as "thin".

And it would not meet specs for mains wiring to be double insulated if it were thin

Here are two examples of very thin flat loudspeaker cable. They are only

Yes, but my question was in response to RolandP saying that it was available for mains distribution (and see, also, my earlier comment about the resistance of such small gauge wire over the necessary distance for rear loudpeakers in a larger room)

That's very similar, and even better (for the OP).
