Compound Driver for Acoustical Applications, AKA "CoDriver™"

and

Repairable Electromagnetic Linear Motor For Loudspeakers And The Like, AKA "NeoSym™" Motor

The cutaway illustration shows the CoDrive compound driver with our "NeoSym™" subwoofer motor. Installed in our robust CB 1.2 sealed enclosure and matched with our SP series signal processor and 1000W RMS digital amplifier, the CoDriver™ has a usable bandwidth of 4 octaves! This extraordinary frequency range enables CoDrive subwoofer systems to integrate perfectly in any application, whether it be a high end music system, studio monitoring, a home theater, or sound reinforcement,

How can a true subwoofer (with the cone area of a 15" driver) in a small sealed enclosure with usable response to below 20Hz still have the "speed" necessary to keep up with an electrostatic panel at 180Hz? The secret is our patented compound driver technology.

The illustration reveals how air displacement of the rear cone is forced through a central vent in the front cone. This "compression loading" creates the rapid air movement necessary to give the speaker "quickness" for good transient response at higher crossover frequencies, while the displacement of both cones sums to create the "volume velocity" necessary for subsonic extension. In addition, our unique NeoSym™ subwoofer motor has the power capacity to take advantage of our 1000 WRMS digital amp, and our proprietary SP2 and SP1 x-over/processors have the filter curves and control flexibility to correctly integrate the CoDrivers™ in YOUR system.
