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.”
The alpha five seven is a product of Inadvance, a small Kitchener based company with a focus on home automation, home theater, and consumer A/V equipment. Inadvance is a manufacturer and installer of custom electronics and automation products.

"...the alpha five seven sounded far better than most similarly priced speakers [at TAVES]. I found it excelled with female vocals. This complex stack of drivers seems to mimic the sound of a single driver!"

"[the alpha five seven is] quite an attractive speaker, and gives the impression of being a well-established product rather than a first attempt"
