MartinLogan Motion 20i GB, ea floorstanding speaker, Gloss Black

The MartinLogan Motion? 20i features an advanced drive-stabilizing dust cap design. MartinLogan built a better speaker The Motion 20 was a heck of a speaker, so why did MartinLogan put in the time and effort to redesign it? Because the best never rest on their laurels. The next-generation Motion 20i delivers a similarly broad soundstage, tight bass, and transparent highs from a new design that improves on the original. This model features a drive-stabilizing dust cap and stiffened motor suspension on its midrange and low-frequency woofers. A solid mid- and low-frequency foundation MartinLogan uses aluminum cones for their unique blend of lightness and rigidity. The Motion 20i uses two 5-1/2" woofers in a "2.5-way" configuration - both woofers cover the lower frequencies, but one goes higher into the midrange, for a smoother transition between drivers. One woofer is positioned low on the front baffle to reduce an unwelcome acoustic phenomenon known as "floor bounce." This approach helps keep the bass and critical midrange frequencies properly balanced. Detail and precision from the Folded Motion? tweeter Perched above the Motion 20i's woofers is the source of this speaker's impressive high-frequency performance - MartinLogan's acclaimed Folded Motion tweeter. Its pleated diaphragm works similarly to an accordion by "squeezing" air to create sound. Because it requires almost 90% less excursion than the typical 1" dome tweeter, response time and distortion are drastically reduced. The diaphragm's increased surface area also provides wide, yet controlled sound dispersion to create a realistic and highly accurate soundstage. Unique crossover network Motion Series speakers feature proprietary Vojtko(tm) crossovers, named after MartinLogan's chief audio technologist, Joe Vojtko. "A Vojtko crossover isn't so much a set of design requirements as it is a philosophy," the company explains. Each speaker's drivers are carefully selected or designed to operate within an inte
