Lawrence, Kan. - MartinLogan expanded its Motion Series selection of speakers to include a high-performance bookshelf model at a suggested $799/pair.

The Motion LX16 speaker features MartinLogan's thin-film Folded Motion tweeter, a 5.25-inch high-excursion woofer and low-turbulence rear-firing bass port. Each speaker features wood-wrapped cabinet with a hand-rubbed, high-gloss piano black or black cherrywood finish.

A perforated steel grille appears to float in front of the speaker, constructed from 0.75-inch-thick MDF cabinets. A solid, black-anodized brushed-aluminum baffle sits flush with the cabinet.

In its Motion series, the company already offers two bookshelf-like speakers, the Motion 2 at $199/each or $400/pair and the Motion 4 at $249 each or $500/pair. Neither is in the high-performance category, a spokesman said, and although they can be used as bookshelf speakers, the Motion 2 and 4 lack a traditional bookshelf form factor because of their curved backs. They're considered by the company as a compact home theater or desktop speaker, the spokesman noted.

 The company will give away a pair of the Motion LX16 speakers at each stop on its ongoing Truth in Sound Tour, at which the company is demonstrating its electrostatic line source CLX Art at participating dealers.
