Amphony Model 1800 Wireless Speaker Kit — Converts Passive Speakers to Wireless, 2x80W Amplifiers, 300 ft Range, Better-than-Bluetooth Digital

Turn your existing passive speakers into a wireless surround system and remove messy speaker wiring with the Amphony Model 1800 kit. This bundle contains two compact wireless amplifiers (each 5" x 3.5" x 2") that connect directly to passive loudspeakers and deliver 2 x 80 Wrms of power. Audio is transmitted uncompressed for true CD-quality sound — a better-than-Bluetooth digital wireless link that reaches up to 300 ft line-of-sight (about 100 ft through walls and ceilings). Each receiver includes a built-in power amplifier using efficient class-D topology for ultra-low distortion, and a proprietary amplifier design maintains a linear frequency response regardless of speaker load — performance that scores highly in amplifier listening tests. The wireless link uses advanced adaptive frequency-hopping to avoid occupied channels and resist interference; a single transmitter carries two audio channels and can stream to as many as four wireless amplifiers. Use additional transmitters to create multiple audio zones throughout your home.
