Bryston 21B³ (Cubed) 3 Channel Power Amplifier
The Bryston 21B³ (Cubed) 3 Channel Power Amplifier impressed the audiophile community with the ultimate fully active loudspeaker system that lets you choose your own amplifiers.
Listeners were free to build 6-channel systems any way they liked. Now Bryston introduces the 21B³-an amplifier dedicated to bringing Cubed Series excellence to an easy to manage package.
Each 21B³ has 3 channels. One is rated at 600 watts, the other two are rated at 300 watts each. Active loudspeaker customers will use the high-powered channel for the bass section and smaller channels for the midrange and high-frequency sections of their 3 way systems. Since the 21B³ is based on their 7B³ and 4B³ amps, it can also be used to power any 3 channels such as the front LCR in a home theatre.
