Martin Logan Motion 15 Bookshelf Speakers.
The High-Performance Motion 15 bookshelf features an advanced resolution Folded Motion tweeter, a low-distortion 5.25-inch high-excursion black-aluminum woofer, and low-turbulence rear-firing bass port for extended bass performance, all in a traditional bookshelf package. MartinLogan’s signature perforated steel grille attaches magnetically to the solidly constructed 3/4-inch thick MDF cabinets on the Motion 15. Hidden discretely underneath the grille, the drivers are held securely in place by a solid, black-anodized brushed aluminum baffle. Folded Motion tweeters and woofers are seamlessly blended with an advanced topology crossover network featuring polypropylene and low-DF electrolytic capacitors, custom wound inductors, and thermal and current protection. The Motion 15 also features recessed custom 5-way binding posts for connection versatility
