DESIGN FOUNDATION OF THE TEMPEST ONE TRANSMISSION LINE SYSTEM
The TEMPEST ONE is a combined line source, planar source design, with the added advantage of optimum operation securely mounted to a room boundary wall, or on designer stands allowing transducer operation immediately adjacent to the pressure zone room boundary. Acoustical operation in the pressure zone confers many sound field benefits, as the wall represents simply an extension of the speaker baffle board itself, directing all radiated sound power directly forward in the listening space. Thus the entire output of the TEMPEST ONE radiates into a hemisphere of free space: a half space or 2pi sound field, rather than into a partial sphere as would a free-standing, in room, direct radiator speaker system. Because the listening space is a half-space, or hemisphere at all frequencies, especially in the bass, where the sound field is truly omni-directional, the radiated sound power is slowly elevated by rising first order room gain, yielding full non-resonant bass power radiation free from transducer resonance at a sharp combined driver enclosure Q factor. In a multiple driver line source array, the effective radiating driver surface area is large, and planar, the TEMPEST ONE does not follow the inverse square law diminution of sound intensity law typical of small compression drivers, but is rather governed by rate of attenuation of 3 dB for each doubling of distance from the transducer source. The TEMPEST ONE is an electromagnetically driven quarter wave, first order transmission line system, and exhibits nearly perfect well damped resistive behavior: it is neither inductive or capacitive, as either condition places current and voltage waveforms out of phase with each other. As a linear, first order, resistive transducer system the TEMPEST ONE is a natural, supremely NEUTRAL voice to the most complex and demanding musical waveforms.
