This loudspeaker is the culmination of over twenty years of product design at three speaker companies including HUMAN speakers.

The cabinet combines form and function in an elegant diffraction reducing design. The large front panel bevels reduce the speaker's tendency to diffract its own sound waves with its front corners. The result of this arrangement is a more spacious, involving and musical, less "boxy" sound.

The one inch concave dome tweeter continues the transparent character of this speaker. The light weight and stiffness of the aluminum allow it work from the midrange all the way out past the range of human hearing, without the coloration or exageration associated with most tweeters, while the ferrofluid cooling enables plenty of power handling. The vanishingly low distortion and remarkably extended frequency response make this the ideal tweeter for a two way system.

The tweeter goes low enough to allow the eight inch woofer to be used only for the frequencies which it can properly disperse throughout the room. The problem of "beaming", which sometimes colors the sound of a speaker more than anything else, is thus practically eliminated.

The woofer's design allows it to be direct coupled, since it has a natural roll off beginning around 1800 Hz. This eliminates complex crossover elements which can rob the sound of immediacy by interfering with your amplifiers damping ability and inducing unwanted phase shift. All the crossover that is needed is a simple high pass filter built with high quality air core inductors and 400 volt film type capacitors.

The long throw, low resonance eight inch woofer is acoustically coupled to the ten inch diameter passive radiator. Together they reproduce the lowest musical notes with tremendous authority and more accuracy than most systems. Their combined radiating area is about the same as the typical twelve inch woofer, yet the speed, control, and dispersion characteristics of the eight inch woofer are retained.

All of these components are manufactured one at a time by hand to exacting tolerances here at my Factory, and all the finished speakers are carefully tested and auditioned to ensure complete adherence to the design standards.
