Summary: The signal range claims are not true. The two components in my case are at the same elevation,22' apart, and have 1 inside sheet rock wall and 1 open doorway between them. If someone under 140 pounds walks between then, there is a momentary loss of sound. The rest of the time the sound is great.
Summary: We just had hardwoods put in. There is no way to run speaker wire to the rear channels anymore without carpet. I got this just last night and installed it using the wire I had wired under the carpet. Plug and play on channel 1 and Option 1 for non-JBL speakers. It worked flawlessly. So far no interference from any items. I didn't run the microwave or try to use the home phone yet, but no other wireless signals from neighbors, etc has had an impact *yet*.
Summary: I was worried after reading some reviews about wireless speaker systems, but I have been impressed with the JBL system. It was fairly easy to set up and gives you the old school surround sound. We tried a sound bar, but it just wasn't the same, so we went looking for a wireless setup. There is an occasional pop from the system, and by occasional I mean 3-4 in the last month and a half I have had it hooked up to the receiver. Overall, very impressed with the JBL system.
Summary: I bought my second module to do a Zone 1/Zone 2 configuration with my receiver. I used one set to set up the back speakers in my living room and then used the second set of receivers to set up speakers in my kitchen. I had some connection issues with the kitchen set due to thick walls in an old building, but I removed the antenna by the receiver about 2 feet over and now I've had no issues at all.
Summary: I bought this unit to control rear surround-sound speakers in my living room, where I did not want speaker wires strung along the floor. I wired the transmitter to the rear surround speaker outputs on my Yamaha 5.1 receiver, so the rear speaker volume would be controlled at the receiver. Zone 2 applications would, of course, have different requirements, and the unit does come with a remote to control the volume. I'm not using it, however.
Summary: This unit performs and sounds just as good as when I had my surrounds wired. I've had absolutely no interference from, or to my 2.4GHz wireless network. Even if there was interference, the transmitter/receiver have a 4 position "ID code" selector. Changing the position on both should resolve the problem (according to the manual). The front input jack is a great feature, as I can plug-in any device with a headphone jack to play music.
Summary: Installed in a Denon-Boston Acoustics 5.1 system to contol the 2 rear surrounds. Works well, no problems to date. I've reviewed other wireless solutions but this one is the best of the bunch. A bit on the expensive side, but compared to the cost a professional "hard wire" install for rear channels, this is a "no brainer".
