The Motion 20 is a breathtaking visual statement regardless of its compact dimensions. Dual 5-1/2" aluminum cone woofers are paired with a rear-firing bass port for extra punch in the low frequencies.  With the addition of our Folded Motion tweeter it's a design that delivers solid low-frequency reinforcement, superb sound dispersion and precise, highly dynamic high frequencies.  


Folded Motion® Tweeters  

The signature Folded Motion tweeters utilize extremely low mass diaphragms that "squeeze" air, and require significantly less excursion than the typical 1-inch dome tweeter, which drastically minimizes distortion while providing a lightning fast response time.  The increased surface area also provides a wide, yet controlled sound dispersion to create a realistic and carefully etched sound stage.
