At only 18 lbs, this subwoofer handles up-to 3times more power, has a considerably higher linear and maximum excursion, andaudibly lower distortion, while weighing as much as 66% less than other Ultra-PerformanceSubwoofer (woofers with an excursion capability of greater than 2.5”).These subwoofers made by other companies can weigh as much as 55 lbs. On theother hand, the Critical MASS Ultra-Performance Lightweight Subwoofer will notonly play louder and handle more power, but it will also play in a smaller box, andtherefore, can save you as much as 100 lbs from subwoofer system weight whencombined 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 resultingin up to 1/10th of a second off your 0-60 mph times, or as much as 1 car lengthfaster. So the next time you plan to invest $1000 on an exhaust system, keep in mindthat you may have already lost your expected performance gains, unless you are usingCritical MASS UL-Series subwoofers and speakers Tech info: Subwoofer Size: 12”RMS Power handling: 2500 Watts (undistorted power)Peak Power handling: 5000 WattsRecommended Box Volume: 1.2 cuft.
