Rear Channel Wireless Connection: Most wireless add-on speaker kits designed for use with rear speakers (normally labeled as wireless rear speaker kits), connect straight to the speaker output without problems. Again, the is a case in point. Instead, systems such as the can take both line and speaker level connection.
Luckily, more and more electronic manufacturers are coming up with integrated wireless speaker solutions. The 1200W Hi-res Blu-ray Home Theater System with Smart TV and Wireless Rear Speakers and the 3D Blu-ray disc player with Samsung Smart Hub are just typical HTiB solutions of what you can find at present on the market in this respect.
The speaker cable requirements of today's multichannel home theater systems have created a sizable market for wireless speakers. It seems as if everybody wants these things, but the engineering challenges of wireless speakers are steep, and a lot of wireless speakers sound pretty awful. There are a lot of truly dreadful products out there, and so our expectations for the Rocketfish Universal Wireless Rear Speaker Kit were fairly low. (Rocketfish, if you're unfamiliar, is one of the in-house brands of megaretailer Best Buy.) So imagine our surprise when it turned out to be a refreshingly clever product. The "Kit" part of the name was the first hint: the Universal Wireless Rear Speaker Kit doesn't include any speakers. The two-piece system instead features a wireless transmitter and a wireless receiver/power amplifier that can be used with any brand of surround speakers, so long as they use standard speaker wire (not hardwired proprietary connectors). So the "wireless" speakers can be as high quality as your front speakers. There's more good news: Rocketfish's Universal Wireless Rear Speaker Kit is priced low enough--$100--that we can recommend it for use with budget-priced systems, including many home-theater-in-a-box systems (HTIBs).
