Bryston impressed the audiophile community with an ultimate fully active loudspeaker system that let you choose your own amplifiers. Listeners were free to build 6-channel systems any way they liked. Now Bryston introduces the 21B?-an amplifier dedicated to bringing Cubed Series excellence to an easy to manage package. Each 21B? 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 21B? is based on our 7B? and 4B? amps, it can also be used to power any 3 channels such as the front LCR in a home theatre.
