Adding wireless to existing passive rear speakers

[MK1 GIT]

As per title really. Have recently moved things around and would to convert my rear speakers to wireless. As they’re passive I need an amp obviously and then some form of wireless transmitter and receiver.

Anyone done this? I’m struggling to find an answer via Google. Lots of people talk about the wireless interfering with wifi etc…. Anyone got a similar set up or recommendations?

Yes I know wired is better and easier.

The wireless part will just be the audio signal, the amps will have to be local to the speakers, wireless ones are usually active speakers so the amp is built inside the speaker box. They will still need power to each speaker too, so not completely wireless.

Yes, sorry probably didn’t explain properly. I know I will require amp and power and then also wires to the speakers just didn’t want the wires ran across the room from amp to rear speakers so was looking for the wireless audio like you said.


Edit to add;

I have just found this which is kind of what I was thinking. Couldn’t find this earlier.

You can get a BlueTooth stereo amp for buttons.
Then you just need a BlueTooth audio transmitter.
Also available quite cheap.

And hope the delay doesn't notice.

There are lots of ways of doing what you say, at varying price and quality.

Yes, the BT solution is possible. But how many BT transmitters accept speaker level inputs?

Those of us with the right skills can build a little voltage divider circuit to pull speaker level down to line level. However, not everyone can, or wants to learn, or wants another wky home-brew box of wires as well as a BT transmitter behind their amp.

The store-bought ones used by car enthusiasts to attach line-in power amps to head unit speaker out sockets tend to sound crap as well.

Newer AV receivers with a full set of pre-outs are rare or expensive now. It used to be reasonably common at £700-£800, but that was 10 years ago, before the costs of providing eARC and ATMOS and DolbyVision and the recent AV receiver price hikes.

After all of that, there's the BT audio delay to contend with.

There are times when the few extra quid is worth it if the solution is simple, quick to install, and does what the user wants.

At 25WPC (8 Ohms RMS?) it's not going to rock the foundations, but we don't listen at higher volumes that often so maybe it's enough? If it isn't, then either uprating the power supply to give the Class D amp a bit more juice or return it and look at the other solutions.

Personally, I recommend running the cable, but that isn't always practical, especially as more folk are renting now.

I would be interested to see what the amp reports back as the speaker distance with the Marmitek in place. They claim there's no latency, but it's processing the sound and doing a couple of conversions so there has to be some kind of overhead for that.
