MartinLogan Motion Dual 6-1/2" Passive 2.5-Way Center-Channel Speaker (Gloss Black)

The MartinLogan MO50XTIGB is a passive center channel speaker created for listeners who want clear dialogue and convincing on-screen action in a home theater. It belongs to the Motion Series, so it integrates easily with matching front and surround speakers, yet it can also upgrade an existing system that needs a strong, articulate center channel.

Inside the cabinet you will find two 6.5-inch aluminum woofers that handle midrange detail and produce bass with authority. A rear-firing port supports those woofers by extending low-end response without adding muddiness, which is helpful when the speaker sits inside furniture or on a stand below the television.

High frequencies come from MartinLogan’s Folded Motion XT tweeter. This tweeter unfolds air quickly, allowing movie soundtracks and musical content to keep their subtle overtones and pinpoint imaging. Whether it is a whispered line of dialogue or a burst of orchestral cymbals, the top end stays smooth and lifelike.

A Vojtko crossover network ties the drivers together so voices move naturally across the screen. With 94 dB sensitivity and a 4-ohm impedance, the speaker pairs well with most modern A/V receivers or separate amplifiers. Dual binding posts give you the option to bi-wire or bi-amp when you want extra control and power.

The cabinet wears a finish in gloss black that blends with contemporary décor, and a magnetic grille lets you choose a discreet look or show off the drivers. At just under 23 inches wide and a hair over 29 pounds, the Motion 50XTi sits securely on a shelf, in a media console, or on a dedicated stand without taking over the room.

Use it in a living room where family movie nights demand every word be heard, or in a dedicated theater that calls for seamless front-stage integration. Wherever it is placed, the Motion 50XTi delivers the balance of clarity, dynamics, and style that MartinLogan owners expect.
