This is the flagship of the Motion Series. It's a powerful floorstanding loudspeaker featuring a Folded Motion® XT tweeter, 6.5-inch aluminum cone midrange driver, dual 8-inch aluminum cone woofers with rear-firing bass ports, and a proprietary Vojtko crossover network. XT stands for extreme: lifelike details from the lightning-fast Folded Motion XT tweeter, open and authentic midrange performance, coupled with deep, musical bass response. These classic performance technologies have been enhanced by the slightest of modifications, including the drive-stabilizing dust cap design, stiffened motor suspension, and low-mounted woofers to reduce an acoustically harmful phenomenon known as floor bounce. The speaker's enclosure sports increased internal bracing, a reinforced baffle, and a fabric grille.
