This kit has a transmitter and two compact but powerful receivers with a built-in amplifier—measuring 5 x 3.5 x 2 inches (12.7 x 8.9 x 5 cm)—that you can easily mount and connect to a speaker.
Each receiver can deliver 80 watts of power with the efficiency of a regular class-D amplifier and ultra-low audio distortion. The transmitter can send audio signals up to 300 feet in line-of-sight and 100 feet through walls and ceilings.
Measuring only 2 x 7 x 4 inches (5 x 17.8 x 10.2 cm), this small kit allows you to take advantage of a 2.4GHz digital wireless link for crystal clear audio transmission.
This can power your sound system with its 2×40 watts of output, allowing you to convert any part of your house into an audio room without the nasty wires snaking on the floor or ceiling!
Its small size, but, carries a lot of juice, including the adaptive frequency hopping that avoids interference from other wireless devices in your house and full stereo audio transmission without compression for deeper bass and heart-pounding surround sound!
Avantree Lock, unlike the first kits on this list, is only a transmitter and receiver. It doesn’t power your speakers, but with a good setup, this kit is one of the most inexpensive ways to go wireless.
It’s one of the smallest, yet most efficient conversion kits that you’ll find, measuring 1.97 x 0.51 x 1.46 inches and weighs approximately 20 grams! Connectivity could be an issue because it only connects via a 3.5mm audio connector.
