MartinLogan Motion 4i overview

  • 1Description

Enjoy easy connectivity with the MartinLogan Motion 4i 2-Way Bookshelf Speaker. This speaker features push-style speaker terminals with banana plug inserts to facilitate a near-effortless connection. It handles 20 to 150W of power and is equipped with a 1 x 1.4" Folded Motion transducer for highs and a 4" paper cone woofer for low audio effects. It features a 70 Hz to 23 kHz frequency response and is wall-mountable with the included hardware.

Folded Motion Tweeter
The key to the performance of the Motion 4i is the fast response of the tweeters lightweight diaphragm combined with a large surface area, which are engineered to achieve a smooth, refined sound with enhanced dynamic range and clarity. Vojtko crossover topology features air-core coil inductors, low-DCR steel laminate inductors, polyester film, and low-DF electrolytic capacitors for a virtually seamless sonic presentation.
Curved Design
The curved design of the Motion 4i allows it to mount at two different angles with the included wall mount, allowing you to point the sound directly toward the desired listening area for high or low wall-mounting applications. The speaker can even be mounted upside-down if mounted high on a wall. The Motion 4i can also be placed on a stand or bookshelf.
