Founded in the early 90's Critical MASS Audio has established itself over the 30 plus years as one of the finest audio manufacturers in the world. Many even claim Critical MASS Audio is in a league of its own due its unparalleled combination of the highest possible level in sound, design and finish. What is for certain is the proven consistency in delivering excellence for ears, eyes and hands without any kind of compromise - materialized in unique masterpieces. As always made in the USA. Words alone cannot effectively describe the " CRITICAL MASS AUDIO sound". Objective descriptions such as "ruler-smooth frequency response", "ultra fast step response" and excessive adjectives like "neutrality" and "amazing soundstage" could be used however these qualities are a successful by-product of accurate engineering stemming from Critical Mass Audio's goal of reaching for perfection. Sonically, the sheer scale and dynamics of the music in this Car Audio system was bloody extraordinary. The effect was "Audio Oasis! Award material" all the way. The sound was effortless, fluid, natural, organic, and had the sort of transparency that I associate with only the finest sort of designs that I've encountered on this planet. Detail without edginess; dynamics without loss of control; full-frequency-range presentation without humps or valleys... The Critical Mass Audio system was AMAZING!!! If you want the very best in Car - Home - Motorcycle - Boat... The Critical Mass Audio line of Speakers Amplifiers Crossovers and ALL things high-end audio, will be the last stop for you! You have found the best there is.

Technical Specifications:                              BOX TECH NOTES


Subwoofer Size: 12”
RMS Power handling: 500 Watts (undistorted power)
Peak Power handling: 1000 Watts
Recommended Box Volume: 1.2 cuft. (Sealed)
Weight: 4.6 lbs
Motor Type: G.A.P. / Internal NEO Magnet
Voice Coil Type: Ultra-High Temp Dual Coil (Made in the USA)
Voice Coil Diameter: 3”
Voice Coil Impedance: 2 ohm nominal per coil
Xmax (one-way linear excursion): 12 mm (2” peak-to-peak)
Maximum Excursion (one way): 29 mm 
Sensitivity: 94.7 db (2.83V / 1m) (coils in parallel)
Fs (Klipple-LSI): 31 Hz
Qts (Klipple-LSI): 0.57
Vas (Klipple-LSI): 22.9 Liters
 

HIGH-PERFORMANCE ULTRA-LIGHTWEIGHT SUBWOOFER DESIGN:

This driver is made with the automotive performance enthusiast in mind. At only 5 lbs, this subwoofer handles up-to 3
times more power, has a considerably higher linear and maximum excursion, and
audibly lower distortion, while weighing as much as 66% less than other Slim
Subwoofers (woofers with a depth no grater than 5").
These subwoofers made by other companies can weigh as much as 25 lbs. On the
other hand, the Critical MASS High-Performance Ultra-Lightweight Subwoofer will not
only play louder and handle more power, but it will also play in a smaller box, and
therefore, can save you as much as 100 lbs from subwoofer system weight when
combined with the reduced weight of a smaller enclosure (based on two 12” subs).
A 100 lbs reduction in your system weight, translates to accelerations gains resulting
in up to 1/10th of a second off your 0-60 mph times, or as much as 1 car length
faster. So the next time you plan to invest $1000 on an exhaust system, keep in mind
that you may have already lost your expected performance gains, unless you are using
Critical MASS UL-Series subwoofers and speakers.

TECHNOLOGY:

Allows for much greater linear excursion and power handling than conventional
drivers. This Ultra-Performance Subwoofer 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, car-shaking bass.

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
