Today we are looking at the Rocketfish Wireless Universal Rear Speaker Kit. This kit allows you to make any rear 5.1 surround speakers into a wireless system requiring no wires running from your receiver to the rear speakers. Once everything was connected up the system worked flawlessly. As soon as I pressed the connect button on the transmitter the rear speakers synced up. In my room the rear speakers are about 30 feet from the transmitter. There was no lag, popping or other issue noticeable with the sound when watching a Blu-ray movie.
