Most subwoofers consist of a driver in a box, separating the internal volume of air from the room itself.  The driver's motion compresses the air within the enclosure to create bass energy in the room. 

The problem actually begins right there.  Compressing the air within the cabinet, the driver works against the extreme non-linearity of air.  The more it's compressed within the box, the higher the distortion.  Servo-controlled feedback systems can ameliorate this effect to some degree, but most are relatively insensitive to low frequencies and so are less capable of correcting the generated distortion.

How does ELEMENT solve the problem?

ELEMENT uses an alternative technique that dramatically reduces distortion.  The cabinet houses a pair of drivers.  One mounted on the outer surface behind the boundary coupling system, the other mounted inside the enclosure.  The internal driver does most of the work compressing the air, creating a linear pressure area behind the outside driver.  The outside unit drives the room itself and compensates for the distortions generated by the inner-mounted unit!

This design is very different from typical two-driver isobaric systems in two important ways.  First, the volume of air between the drive units is larger, permitting a greater differential of motion that results in less coupling between the drivers.  Secondly, ELEMENT subwoofers make use of separate amplifiers for each individual driver!  This unique design utilizes dual class AB drivers that are optimized and finely tuned in tandem with the HDF cabinet, thus preventing nonlinearities generated by the internal driver from affecting the external drive unit's performance.

The ELEMENT LFX subwoofer draws upon the lineage and worldly success of Demian Martin's previous award-winning designs including those of the legendary Entec subwoofers.  The ELEMENT LFX subwoofer is designed to handle the 21st Century's demands for reproduction of dynamic bass in a home theater application without sacrificing the virtues of musicality and the attributes of accuracy of today's high-end music systems.

CASCADED DRIVER TECHNOLOGY™ and more!

ELEMENT's Cascaded Driver Technology™ employs dual class AB active drivers that are optimized and finely tuned in tandem with the HDF cabinet utilizing ELEMENT's Constant Delay Filter Technology™ to virtually eliminate distortion and coloration in the LFX while delivering true accurate low frequency output.

CONSTANT DELAY FILTER TECHNOLOGY™ with driver optimization for greater differential of motion results in less coupling between drivers prevents nonlinearities.

Getting near-perfect driver motion is only a part of the story.  Launching the energy into the room is critical.  ELEMENT's Boundary Coupling Technology™ spreads the low frequency energy into the room the most linear and effective way in a 360-degree radiation pattern.
