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.
