the Heil air-motion transformer ... clearly superior!
Does it have a Heil'?" This is the question more and more audiophiles are asking. Does it have a Heil air-motion transformer in it? Why? Because If it is not a Heil air-motion transformer, it's not a state-of-the-art high fidelity loudspeaker. Because anything else Js behind the times, outmoded in design, obsolete even before it was built.
This is a fact governed by the laws of physics, not by mere opinion. The Heil air-motion Transformer marts a new era in loudspeaker technology and a new freedom from the problems of speaker mass and inertia. The Heil air-motion transformer is as radical a departure from conventional air pushing' speaker designs as the jet engine was from the propeller. And for the same reason. Where before the driving force of an airplane engine merely served to turn a heavy propeller which reacted poorly with the air, the jet engine obsoleted propellers by applying the driving force directly to tie air itself for a far superior energy transfer.
So it is with the Heil air-motion transformer. Instead of the driving force moving a "voice coil" conductor that moves a cone or dome that sets air into motion by "pushing" back and forth against it. the Heil air-motion transformer applies The energy flowing through its conductor directly to the air as a squeezing pressure potential and therefore eliminates the losses and inaccuracies introduced by transferring energy through a heavy solid to the air. For a dramatic example of how a squeezing pressure is more effective than pushing, when it comes to moving a light substance like air, try to "shot put a chary pit. The "pushing" action doesn’t send the pit very far or very fast because most of the energy is wasted in moving your "heavy" arm and 1-and so that very little goes into actually moving the pit. But now put the cherry pit between your thumb and forefinger and squeeze.
The pressure of your fingers creates a force whose potential is transferred directly to the cherry pit as motion and it accelerates away from your finger mach more, effectively than with the large "shot put" push.
Heil air-motion transformer speaker systems have no "voice coil" no cone or dome surfaces, no fo-ward backward "pushing" motion and achieve their direct transformation of energy through a unique folded diaphragm that "squeezes" air. These Heil air-motion transformers can actually set air into motion five times faster than the movement of their own diaphragms. The results: instantaneous acceleration and a level of performance that approaches theoretical perfection.
Don't undertake an exercise in futility by listening to yesterdays loudspeaker designs. Only the Heil air-motion transformer gives you the dynamic transient- attack, incredible purity, and pinpoint stereo imaging of tomorrow's recordings. Now you'll find two new Heil air-motion transformers in an exciting new loudspeaker marque: the FORTURA PEDESTAL SERIES and FORTURA BOOKSHELF SERIES. These truly advanced systems can be heard by visiting any of the FORTURA dealers shown in the partial list below, dealers perceptive enough to bypass the conventional and understand tie loudspeaker of tomorrow-the Heil air-motion transformer.
