Our verdict

A refined center channel for a MartinLogan Motion system, with a Folded Motion tweeter built for crisp dialogue. Its low impedance load suits a capable receiver, and rear ports need space behind it.

Overview

Home theaters and media rooms built around MartinLogan's Motion series get a voice-matched center speaker with a Folded Motion tweeter between two aluminum cone woofers. It wires to a receiver through bi-wire binding posts.

Dialogue clarity is the strength, thanks to a tweeter that moves air with very little excursion. It matches the Motion floor and bookshelf models for seamless pans across the front. Its low impedance and rear ports ask for a capable amp and some wall clearance.

Who it's for

Owners of Motion series front speakers who want matched voices across the screen get a natural partner. Buyers without an amplifier or receiver have nothing to drive it.

Pros and cons

Pros
  • Folded Motion tweeter for clear voices
  • Voice matched with Motion series
  • Aluminum cone woofers
  • Bi-wire capable binding posts
Cons
  • Low impedance load for the amp
  • Rear ports need wall clearance
  • Frequency response not listed

Performance notes

Dialogue detail comes from the Folded Motion tweeter, which squeezes air instead of pushing a dome, cutting distortion. The twin woofers and rear ports add body to voices, so distance from the wall changes the bass. The crossover blends tweeter and woofers for even tone.
