Car Audio Magazine

This CM-A30th3CH Series Subwoofer Amplifier is the result of extraordinary passion for High-Fidelity. This 30TH anniversary amplifier technology is used in our world renowned $259,000 ESL world reference esoteric audio system. Built using only the finest techniques and materials available today. Critical  MASS amplifiers are manufactured and tested to meet the highest component quality and control standards. Engineered to provide decades of musical enjoyment. "Critical MASS is a Car Audio company whose Super-Fi electronics have made innovation history in the world of high-end mobile sound" CA&E. Critical Mass was formed from the World’s First Car Audio and Enhancement school by one of Car Audio's first innovators and most influential people in our industry who started the world's first Car Audio and enhancement school back in the late 1980s “CMA”, from this school Critical MASS was started in Orlando, FL, in 1990. Till this day parts of the technical principles and teachings of CMA are used industry wide in Mobile Electronics teachings and books by associations such as MERA and CEA. Over the past decades Critical MASS has continued to innovate and now leading the way with the Critical MASS $259,000 CES-5.1 one of a kind Esoteric ESL sound system. Not only does Critical MASS make the Best and most expensive car audio system in the world, but this system (which integrates this Esoteric ESL Series amplifier) is so good, that when Car Audio Magazine tested the least expensive part of our $259,000 ESL system “the UL12” called it " Perfect ", and "the BEST" and added that it was so good that he would sell a few things, to own one because it's worth every dollar! In  addition the Critical MASS UL12 was rated #1 over all others by Car Audio Magazine, including companies such as JL Audio, Image Dynamics, Alpine, Xtant,  Kicker, Arc Audio, MB Quart, Digital Designs, Cerwin-Vega, Orion, Phoenix Gold  Earthquake etc…  In other words  Imagine how good the rest of the system must sound if the least expensive part of it is the world's BEST? You will not have to imagine much longer as theCM-A30th3CH series amplifier you just purchased uses many of the same Critical MASS quality components as the amplifier used in our $259,000 electrostat system.
