a loudspeaker as translator
The Loudspeaker as Translator.
A loudspeaker translates electrical impulses into sound waves: Ideally, the loudspeaker/translator leaves nothing out and puts nothing extraneous in. It doesn't omit or color or mask The perfect translator is perfectly simple.
Simple and impossible, until the Heil Air-Motion Transformer revolutionized sound reproduction. The Heil midrange/high-frequency transformer is the perfect translator
There is only one compact system with a full-size Heil. The ESS amt-la Bookshelf system Perfectly simple

Air-Motion Transformation: Midrange/High Frequency The Heil transformer, like most significant innovations, is much appreciated but a little mysterious. It is mandatory equipment for master reproduction techniques, yet the technological basis for its performance is often taken for granted Actually, the Heil Principle of Air-Motion Transformation is as elegantly simple as it is effective.
The transformers diaphragm resembles a lightweight, pleated curtain mounted between powerful ceramic bar magnets. Conductive strips on the sides of each pleat cause the pleats to expand or contract in step with the signal. The air is squeezed out. and accelerated to five times the velocity Of the diaphragm itself. In effect, the
Heil transformer uses air to move air, operating on the principle of pneumatic leverage
Cone driving systems, on the other hand, are sluggish and inefficient by design The cone's mass is huge; driving energy is largely devoted to overcoming its great inertia. The cone resonates and can break up" at high frequencies. A cone driver only pushes air like a piston, in a one-to-one ratio
The Heil driver's air-motion transformation ratio is five^ times better than that of any conventional speaker. W
Other crucial design parameters are solved by the Heil Air-Motion Transformer. The extremely light weight of its diaphragm eliminates resonance. Since the driving impulse is spread uniformly over the diaphragm surface, harmonic distortion from cone breakup" is non-existent These are inherent benefits of the Heil design. For conventional speakers, they remain problematic goals
Remarkable dispersion characteristics are another natural advantage of the amt's design. With a 120° pattern at 16 kHz, the amt maintains a solid expanse of stereo imagery to frequencies beyond audibility Whatever the speaker/listener positioning, imaging is precise and penetrating.
The audible payoff is clarity, a perfect re-creation of the music's fine and changing texture. Female vocal depth,
