Each HEX

™

 Pro component set comes with a pair of programmable crossovers.  These crossovers 

use a combination of 12 and 24 dB/oct slopes to optimize the output of the tweeter and mid-bass 
driver.  Each crossover features complete tweeter level, phase, and bi-amp programming 
capability.  An LED found on top of the crossover is used as a power limit indicator.  When brightly 
lit, it indicates that maximum power is being delivered to that channel.

The following illustration shows how to connect one channel of the HP650 component system.

Under the sliding cover on the crossover is where the programming 
controls are located.  The tweeter level control has four settings:  +2, 
0, -2, -4 dB.  This is adjusted by changing the combinations of the 
two toggle switches labeled "TWT LEVEL".  Use the key to the right of 
the switches to configure tweeter level control.  Switch the "BI-AMP" 
switch only when running the crossover with a bi-amped signal.  The 
"PHASE" switch swaps the tweeter 180 degrees out of phase for off 
axis tweeter installations.

The illustration above shows the parts included and correct mounting assembly of the HEX

™

 Pro 

component mid-bass drivers.  Be sure to check the available mounting depth before installation 
begins.  Use of the foam gasket is recommended to ensure a proper seal between the speaker and 
mounting surface.

When mounting the tweeters, make sure 
desired location can accommodate the 
hole size, over all diameter and depth 
required.  Cut a 2" hole in the surface 
chosen and feed speaker wire through.  
Remove the tweeter mounting ring by 
unscrewing it counter clockwise.  Connect speaker 
wire to tweeter terminals and mount tweeter in hole 
using provided screws.  When tweeter is secure, replace 
trim ring by screwing it on clockwise.

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.  Conventional 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.
