Make your existing speakers wireless with Amphony's speaker kit. Eliminate messy speaker cables in your room. This kit includes 2 wireless amplifiers that each deliver 80 Watts power to any passive speakers.

The transmitter sends audio up to 300 feet (100 feet indoors) even through walls and ceilings. You'll get true CD quality with uncompressed better-than-Bluetooth digital wireless audio. Each receiver has a power amplifier built in and connects directly to a passive loudspeaker. The built-in amplifiers deliver the efficiency of regular class-D amplifiers at ultra-low audio distortion. A proprietary amplifier design ensures a linear frequency response regardless of the speaker load. It excels in amplifier listening tests.

Each wireless amplifier measures only 5" x 3.5" x 2" and is easily mountable to a speaker.

The wireless transmission employs advanced adaptive frequency hopping. It avoids frequency channels occupied by other wireless devices and is highly robust against wireless interference.

Each transmitter sends 2 audio channels to up to 4 wireless amplifiers. By using multiple transmitters you can create several audio zones in your house.
