SOURCE: Can Acoustic Research wirless speakers be used for surround?

yeah, I looked it up on thier website. Here is what they say.

Warning: This product is designed to work with line level outputs or headphone outputs only.

DO NOT connect it directly to speaker outputs as it will permanently damage the transmitter.


You can use these as surround speakers if you like. You just need a line level surround output on the receiver. Most high end receivers have this feature but, you may only have speaker level outputs.

If that is your case the only option you have is to use a "speaker to line level adapter".... http://www.crutchfield.com/p_543ADP12/Russound-ADP-1-2-Speaker-level-to-Line-level-Adapter.html?tp=9070

Now crutchfield.com is always a little high on prices but if you look around I have seen them around $10 online.

Good luck with your project.

I have a pair of acoustic research "active partner" speakers in need of a power adapter. Above the entrance of the plug in print it has DC 11.5 V. Need a compatible adapter.


DC 12v adapters are common and I think that would work. The similar "Powered Partner" speakers used a 14v DC adapter. Just check the size of the plug and the configuration (center pin is +). Radio Shack and other sellers have universal adapters.

The power supplies / ac adapters for my AW-871 speakers were both lost in a recent move. The speakers show input of 15v center + but no power spec. Do you have a suggestion for replacements? Thanks for...


Higher voltage then required is not so recommended, internal circuit may over voltage driven. some power amp max limit may fall within 18V only. See this link If your speaker power less then 30w you can choose 15V 2A will do or else select higher spec.

Cuoul i replace the tweeter with any 1 inch tweeter other than acoustic research?


Providing you match the power and ohm rating of the acoustic tweeter yes. You could of course have an higher rms/watts rating than the original, but not lower. The ohm though must be the same. The only thing that might happen is that it might sound different to the other speaker, as the tweeter sound quality could be better or worse than the acoustic. Of course you could buy two and replace the other speaker one too!

I have wireless speakers and the transmitter stopped working. Nothing happens when you plug it in--??? It's only a month old. AW872


Hi I also post in here , so that you can let me know how it goes.

Try unplugging the transmitter from power adapter, if it also has batteries remove them. Also unplug transmitter audio cable.

Then remove batteries/unplug adapters from speakers.

Wait few minutes and reconnect the system.

This is a proper hard reset, and can fix minor problems.

If when you re connect the transmitter does not glow, or you do not have sound on one or both channels then there is a fault.

Check the transmitter audio cable, a short in there can cause troubles.

If you find no problems , then unit is defective, as it is under warranty contact Acoustic Research to validate the warranty here and get the transmitter or the whole set replaced.

AC adaptors replacements


You will not have any Problem What so ever.
18V is operating Voltage,
0.7A is Max of Current it (Power Adapter) is providing.

The Load (AR) is operating (Uses Current) between 0~0.7A (Even Less)
Therefore 1A Adapter is actually safer to use.

-------------------------------

Think as, your electric company supplies 100A Service,
and you have only AC is running at 10A.
