alpha five seven
The Bowhead alpha five seven is the next evolution in loudspeaker design.
Based on a simple idea that sparked a decade of design and research; the concept that each frequency band should be free to move independently of all others.
The result is a speaker unlike any other before it.
With 9 drivers and 8 independent channels it is quite possibly the most complex speaker ever made, yet each channel has a direct and simple signal path. Each driver is directly coupled to its own amplifier. The analog crossover network is employed before the amplifiers where the signal is easily dissected and noise is easily rejected.
From the analog crossover network to the 9 independent amplifiers every component is operating well below its intended maximum. Even at maximum input levels, the circuitry effortlessly produces a distortion free output.
Simply, the “8-way analog active loudspeaker.”
