A compact floorstanding loudspeaker with a performance that is anything but small, the Motion 20i features a Folded Motion® tweeter, dual 5.5-inch aluminum cone woofers with a rear-firing bass port, and a proprietary Vojtko crossover network. Motion 20i delivers the classic broad soundstage of the Motion Series from a newly designed enclosure enhanced by drive-stabilizing dust cap design, stiffened motor suspension, and strategically low-mounted woofers to reduce floor bounce - an acoustically harmful phenomenon where sound reflected off the floor interferes with direct sound. The speaker's enclosure features a reinforced baffle constructed from 18mm MDF for vibration control and includes a magnetic fabric grille. The Vojtko crossover uses custom air core coils, low DCR steel laminate inductors, and polyester film capacitors to keep each driver operating within its optimal frequency range. Perfect for two-channel audiophile listening or as the foundation of a high-performance home theater system.
