MartinLogan LX16 Piano Black (Ea.) Bookshelf Speaker For the Motion LX16, MartinLogan's signature perforated steel grille appears to float in front of the solidly constructed 3/4-inch thick MDF cabinets. 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 LX Series also features recessed custom 5-way binding posts for connection versatility. The Motion LX16 is available in two luxurious high-gloss finishes; Piano Black or Black Cherrywood. Our new high-gloss black cherrywood finish has deep cherry undertones and appears almost black in low light, giving them a unique and understated elegance that blends into any environment. ***Single speaker - Priced and sold individually.***
