About the Motion XT B100

The MartinLogan Motion XT B100 is a high-performance bookshelf speaker designed for maximum performance without requiring a tower speaker. It features the Gen2 Obsidian Folded Motion XT Tweeter with a 40% larger surface area (12.4 in² / 79.8 cm²) for clean, detailed high-frequency reproduction and lower distortion, paired with a 6.5-inch (16.5 cm) Nomex-Reinforced Kevlar cone woofer in a cast aluminum basket with non-resonant asymmetrical chamber and unibody construction for precise mid-bass. The 2-way design uses an upgraded McCracken-Vojtko crossover at 2,600 Hz and a rear-ported bass-reflex cabinet. It supports bi-amping/bi-wiring via custom 5-way binding posts and includes a threaded base for the optional STAND25 stand. Finishes include Gloss Black, Walnut, and Satin White. Ideal for stereo or home theater with wide dispersion (90° horizontal x 45° vertical) via Motion Waveguide.
