This wireless adapter really works!
Crutchfield Customer Review (What's this?)
I was very skeptical about replacing my sub woofer cable with a wireless device because frequency range is very important to me. But I spoke to two people that are using it and they confirmed that the signal is proprietary and un-compressed, so I decided to give it a shot. This adapter is truly plug and play. It took me less than minute to connect and synch. And I cannot discern any difference in sound whatsoever. This SCW-100 is the real deal.
Pros: Quick and easy to install. Allows free movement of the subwoofer to any location close to a power outlet. The sound is every bit as good as that experienced with a quality cable connection (you should still use a very good cable from your receiver to the adapter).
Cons: Honestly, I have not experienced any negative aspects to this installation. It just works.
