HIGH-PERFORMANCE WOOFER DESIGN:

This driver is made with the automotive performance enthusiast in mind.

Designed at 2ohms to take every watt from your amplifier because its made to perform in every way.

This woofer handles up-to 20 times more power, has a considerably higher
linear and maximum excursion, and audibly lower distortion.
This Critical MASS High-Performance woofer will not
only play louder and handle more power, but it will also play in a smaller box.

TECHNOLOGY:

Allows for much greater linear excursion and power handling than conventional
drivers. This Ultra-Performance woofer utilizes the G.A.P. configuration technology, 
which results in up to 2.5 times more X-max than conventional motor designs.
Huge, vented, NEO motor structure. Utilizing the latest and best high temp,
high grade Neodymium-Iron-Born magnets, which generate up-to 20 times more magnetic energy
than conventional ceramic magnets of equivalent size. This design keeps the
motor running cool, enabling much greater power handling capability than conventional
Neo designs.
 
CARBON FIBER SANDWICH CONE:

This cone is one of the only cones that will withstand 2000 Watts of peak music power.
The Lightweight Carbon Fiber Sandwich Cone increases rigidity, and therefore efficiency,
which ultimately means more, undistorted beautiful sound for decades to come.



MADE BY CRITICAL MASS AUDIO SQ PRO SOUND CLASS

REAL CARBON FIBER CONE

THIN FLAT SHALLOW MOUNT, FITS ANY VEHICLE

below is a quote from USACi sound quality World Champion

"I should preface this review with exactly who

the listeners are: Robyn - USACi sound quality

World Champion and me - both musicians and

audiophiles. Needless to say, We are a tough

bunch to impress. The overall transparency is

crystal clear, giving us the sonic illusion that the

musicians were performing over the engine. I really

can't express how happy we are with this set

- and every other Critical MASS product we've

had the pleasure of listening to!
