The high-performance Motion 15i bookshelf speaker features a Folded Motion® tweeter, a 5.25-inch aluminum cone woofer with a rear-firing bass port, and a proprietary Vojtko crossover network to deliver refined sound with stunning dynamic range and jaw-dropping clarity. Motion 15i delivers the classic broad soundstage of the Motion Series from a newly designed enclosure enhanced by the slightest of modifications, including the drive-stabilizing dust cap design and stiffened motor suspension. The speaker’s cabinet sports a reinforced baffle and a fabric grille.
MartinLogan's premier Motion Series speakers are available in three luxurious finishes and matching metallic trim—gloss black with black grilles and gunmetal grey trim, matte white with silver grilles and silver trim, and red walnut with black grilles and champagne colored trim.
