Thermal-Dyne eXtreme
™
is a fundamentally different solution. The concept is simple, eliminate the
detrimental effects of heat in a loudspeaker system. The solution however, is quite complex. Our
engineers decided to start with a fresh sheet of paper and build a new line of products that addressed
the thermal problems and shortcomings of conventional designs while significantly raising the existing
level of performance.
To understand TDX
™
speaker technology, it must first be compared to that of a conventional speaker
design. At the heart of every speaker is a permanent magnet motor structure that provides the
magnetic energy, or force to move the voice coil back and forth within the magnetic air gap. Conven-
tional speakers use a large ceramic magnet surrounding the voice coil that actually retains heat rather
than dissipating it. TDX
™
motors use a small but very efficient high temperature Neodymium magnet
mounted inside the voice coil. The geometry, venting and material selection for the motors have all
been optimized for ideal thermal dissipation. The TDX™ thermal efficiency is nearly (5) times greater
than conventional designs. In conjunction with the motor design, TDX™ Technology utilizes die-cast
aluminum frame structures to act as a heat sink for the encapsulated motor structure. To insure
maximum heat transfer from the encapsulated motor case to the aluminum frame, a special thermal
paste fills any surface voids that may be present in this mating surface.
The evolution of TDX
™
Technology can be seen in the new HEX
™
Pro series of products. The new HEX
™
Pro component systems take this TDX
™
Technology and expand on it to maximize the benefit for
superior full spectrum audio performance. To faithfully reproduce an extended frequency range, the
materials and design must be optimal. This coupled with a demand for very high power handling, is
extremely challenging. These systems utilize an improved version of our legendary HEX
™
cone, our
patented dual-tuned chamber tweeter along with our extruded aluminum, high power, programmable
crossover to make the very best speaker system available in mobile audio. Period.
