You get involving surround sound without installation hassles!

Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.



Transmitter: The system comes with an RF transmitter that connects to an audio source via attached speaker input wires. The transmitter sends a 914 MHz signal to the receiver, using one of four selectable transmission channels.

Receiver: The receiver "receives" the RF signal from the transmitter and also has the same four selectable transmission channels. The amplifier built into the receiver is a digital design which is very efficient and limits heat output. The speakers are connected using spring terminals on the back of the receiver.

Auto Standby: Both the transmitter and receiver have an auto standby mode, both turn off when not receiving any signal.

LED: Both the transmitter and receiver have an LED which lights green when in use and red when in standby mode.

Antenna: Both the transmitter and receiver have an antenna mast which flips up and adds about 3.25 inches to the overall height.

Channel Button: Both the transmitter and receiver have slide switches allowing you to select transmission channel 1, 2, 3, or 4



  • Audio Input: Attached speaker wire, stereo left and right

An quality alternative to ugly cables

Written By Ahmad, Tampa, FL on Friday, June 30, 2006
I'm surprised more companies don't make kits like this. There are a lot of people who want properly positioned surround speakers but balk at the idea of punching holes in walls and climbing around in the attic just to run wires without spoiling the aesthetics of their living room. If that describes you (as it does me) then I highly recommend this kit. Very easy setup. Solid build quality. Excellent signal quality. And you are free to choose your own speakers (within the recommended wattage of course).

There are no major cons that I can see. One minor con is that the transmitter's leads for L/R Surround are very thin gauge. More robust wires would be nice but this is a minor quibble.

Crutchfield Customer Review (What's this?)
This product is everything I'd hoped for. My receiver and transmitter are about 50ft apart, and provide good sound quality with very little interference. The only (minor) negative point is the bare-wire connections on the transmitter, and spring terminals on the receiver. I would much rather see RCA jacks.

So Simple and So Perfect

Written By Jason, Dallas, TX on Friday, March 24, 2006
Crutchfield Customer Review (What's this?)
Why has this not been available until now and how do more people not know about it. Wireless setup was so easy and sound quality is awesome. If you are not pre-wired for surround and you don't want to have to tuck your speaker wire across your living room or can't, this is the best product available that supports any manufacturer's speakers.
