Motion 15

About the Motion 15

The Martin Logan Motion 15 bookshelf speaker employs a 2-way design with an advanced resolution Folded Motion tweeter (1" x 1.4") and a single 5.25" aluminum cone midbass woofer housed in a non-resonant asymmetrical chamber with a rear-firing bass port. The Folded Motion tweeter uses a low mass diaphragm that moves air perpendicular to folded ridges, minimizing distortion and providing a wide, controlled sound dispersion (80° x 80°) for a realistic soundstage. The woofer features a rigid structured dust cap to reduce cone break-up and distortion, delivering rich and deep bass. The speaker is finished in luxurious high-gloss wood veneers such as Black Cherrywood, Piano Black, or White, and is voice-matched with Martin Logan ESL speakers. It is designed for use with amplifiers rated between 20 and 200 watts per channel and has a sensitivity of 92 dB and an impedance of 5 ohms. The cabinet is constructed from 3/4" thick MDF with a magnetic perforated steel grille and measures 11.4" H x 6.8" W x 9.5" D, weighing 12 lbs. It includes a 5-year warranty with registration.
