Imagine a world without wires. Now open your eyes and see the AW-871 speakers from Acoustic Research and realize that the dream is real. These two channel speakers come with a myriad of features that make them a joy to use. They operate in the 900MHz frequency band and are switchable between three channels to let you use multiple devices in the same area without interference. You can set the speakers to Left, Right or Mono. When set to Left and Right you get a stereo signal that you can put anywhere. The Mono setting lets you put the speakers in different rooms so that more people can listen. The 900MHz frequency setting lets you not worry about walls and gives you a 300' range from the transmitter. Speaker power is provided by either eight C-cell batteries per speaker or the included power AC adapter. If you use rechargeable batteries, they'll charge right in the speaker so you don't have to worry about taking them out and replacing them.
Anyone who has installed a speaker system knows the worst part is figuring out how to hide the unsightly speaker cables, especially if your speakers are located across the room from the receiver. Enter this pair of Acoustic Research stereo speakers, which resolves the dilemma by eliminating speaker wires altogether. The system's powerful transmitter broadcasts its 900 MHz signal through walls, floors, ceilings, and other obstacles, giving listeners a wide array of installation options.
Looking for a pair of high-quality speakers for the upstairs bedroom? No problem. Want to enjoy your favorite tunes in the basement without running speaker wire through the floor? Easy. Thanks to the system's 300-foot range, almost any home speaker scenario is possible, including positioning the speakers outdoors so you can provide the soundtrack for your neighborhood block party. And fortunately for listeners, the wireless setup doesn't compromise the quality of the audio, as the rich signal is drift- and static-free.
Each 10-watt speaker employs a 4-inch woofer and 1-inch dome tweeter, with a left/mono/right switch for added versatility. The speakers also include integrated power, volume, and tuning controls along the front faces. In lieu of an AV receiver, listeners can connect the speakers directly to most audio sources, including TVs, DVD players, VCRs, computers, and portable audio devices such as MP3 players. Alternately, they can connect the speakers to the rear channels of 5.1 surround sound receivers and take full advantage of the wireless design.
Each of the speakers comes with its own AC adapter, though listeners can also install eight C-cell batteries per speaker for complete cordless use. The speakers even recharge ni-cad and NiMH batteries when plugged into an AC adapter. Other accessories include a 1/4-inch headphone adapter and a "Y" cable that connects the transmitter to the audio source.

1) After setup, they work better than I had expected. It appears the system has internal frequency monitoring that allows them to self-adjust, and they do a good job of it. I've gotten very little static even in a high-density neighborhood, and with a houseful of other wireless devices. When static or fuzziness does occur, it seems to be effectively and automatically "dealt with" in a few moments.
2) There are a few clever but non-intuitive features that mean you actually need to read the operator's manual on setup, rather than intuit your way through. I thought it was so simple I could just guess, which had me scratching my head for a few minutes wondering why things weren't working. But the answers were all in the manual, such as the need to pre-tune the transmitter appropriately (a blue flashing light on the transmitter will tell you when your tuning is correct), to turn on the speakers with a brief push-and-hold of the volume control, and to turn off the speakers with an extended push-and-hold. Many of the negative comments from other users posted below, such as "When I tried to recharge nonrechargeable alkaline batteries in them, they leaked" (no kidding!) and "I wish there were an on-off button on the speakers" (there is!) and "The speakers would not work until I turned them on" (no kidding!) seem to come from people who blithely ignored the manual.
3) Check your output device (whether TV/amplifier/stereo/computer/ipod or other) to see if it has a nonvariable (fixed) line out. That's what these speakers want and need. You can fry the transmitter with a variable line out that's turned up, so be careful if you don't have a fixed line out. My output device, a TV, offered either variable or fixed line out (a menu option) so I had to figure out how to change the TV output to fixed. Setup would have been faster if I'd known about this beforehand.
I'm looking forward to adding rechargeable (preferably NiMH) batteries to the speakers and taking advantage of the auto-recharge option afforded by the speaker power supplies. I'd love to move these speakers around the house, completely independent of all wires, including power supply wires.
I'm giving these speakers 5 stars because I can't think of any obvious oversights or deficiencies in their design, and because they exceed my expectations in several ways. I used to have to blast our livingroom TV to hear it from the kitchen, and now I can keep the volume at a moderate level right in the kitchen, where I need it. A quick changeover from the TV to the computer allows me to podcast to anywhere within the house. Nice.
Setting them up was trivial: use a switch on each speaker to say which channel it is for. There's another switch to choose among several transmission channels to be used. Upon powering the speakers, without playing anything on them, I bumped the volume to the maximum. Unfortunately the speakers had a constant noise produced by the built-in amplifier. To make the matters worse, standing in between the transmitter and the speakers, the noise volume changed quite a bit, a sign of radio interferences. The transmitter's audio cable seems to be a cheap quality cable, without proper grounding which could explain some of the noise.
Playing music on them was OK for some computer speakers. I wasn't thrilled however by the level of noise, even with the volume close to maximum, the noise level was unbearable. After turning off the music in iTunes I couldn't stop but notice the constant noise coming from the speakers. My MacPro produces a fair amount of noise, but the one produced by these speakers was higher than that of the computer, similar to that of a constant air conditioning system running in an office building.
I ended up returning them. The specs are great, but the delivery falls way short. Using cheap materials to save cost does have its own costs I guess.
Note: Speakers need to be plugged in to a power source or you can use batteries. Just make sure you have one of the two available to get the party started.
Have had these for 3 years now and still happy with them. They do still have the fuzz / hiss / snap / pop from time to time, which detracts from a five star review . I would still purchase these if the price was right but I would also look at more alternatives in wireless speakers and other streaming products all together.
I have read a lot of negative reviews, but people need to understand wireless IS NOT PERFECT.
