With BH550 we're building on everything that people loved about the original BH250, by simply throwing in more of what made the amp so innovative. You get more power, more punch and more creative features without compromising with the original's ultra-lightweight design. On top of that you get a highly intelligent EQ section, and a built-in tuner.
