Our take on the MartinLogan Motion® 30

by Steve Kindig

Your home theater's most important speaker

The center channel speaker is the workhorse in a home theater system. It has to reproduce clear dialogue and special effects that keep your eyes and ears glued to the movie action. A high-quality center speaker is a great investment for any surround sound setup. Try to choose one that's as closely matched as possible to your front right and left speakers, so that as sound moves across the front stage, it stays seamlessly realistic.

Clear dialogue and effects from a compact center

MartinLogan's Motion 30 center channel delivers clear, accurate movie dialogue and robust sound effects for a home theater experience that's truly cinema-like. This speaker takes advantage of one of MartinLogan's most advanced technologies, the Folded Motion™ tweeter, to create detailed, dynamic center channel sound that immerses you in the on-screen action. This speaker's clear, open sound makes it a perfect center channel partner to MartinLogan's Motion 30 floor-standing speakers.

MartinLogan Motion 30 center channel speaker

MartinLogan's advanced Folded Motion tweeter produces clear, open highs.

Folded Motion tweeter for detailed sound

MartinLogan's innovative Folded Motion tweeter uses a pleated diaphragm that works like an accordion by "squeezing" air to create sound. It requires about 90% less excursion than a typical 1" dome tweeter, resulting in quicker response time and much lower distortion. The tweeter's controlled sound dispersion creates a focused soundstage with a real sense of presence. Voices, effects, and music all come through with lifelike clarity and texture, but without a trace of harshness.

Bass that keeps pace

The Motion 30 uses dual 5-1/2" aluminum cone woofers to supply fast, clean midrange and lower-mid frequencies that blend in seamlessly with the Folded Motion tweeter. A low-turbulence rear-firing port extends bass performance, but keeps it tight and tuneful.

Angled cabinet design

This center channel speaker is sized to fit inside most standard audio-video cabinets. The speaker's angled enclosure is a nice touch for versatility. No matter where you place it, you can direct the sound toward your ears. Place it beneath your TV firing up toward your listening position, or mount it high and flip the cabinet upside down to aim sound down into the room.

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.


Folded Motion Tweeter: MartinLogan's Folded Motion tweeter helps give the Motion 30 center channel loudspeaker its natural, realistic high frequency sound. Lightning fast transient response, combined with a large surface area (8x that of a typical 1" dome tweeter) creates clear, dynamic, and precise sound. The 1" x 1.4" Folded Motion tweeter works by moving air (which creates sound) perpendicular to the folded ridges of the diaphragm, similar to how an accordion works. This extremely low mass diaphragm "squeezes" air and requires almost 90% less excursion than the typical 1" dome tweeter, which drastically minimizes distortion while providing a lightning fast response time. The increased surface area also provides a wide, yet controlled sound dispersion (80°x80°) to create a realistic and carefully etched sound stage.

Dual Aluminum Cone Woofers w/ Rear-Firing Port: Two 5.5" aluminum cone woofers with a cast polymer basket housed in a non-resonant asymmetrical chamber flank the Motion 30 center channel speaker's Folded Motion tweeter. The aluminum cone woofers use a rigid structured dust cap and butyl rubber surround to reduce cone break-up and distortion. The two 5.5" woofers are paired with a rear-firing bass port to deliver higher output and audibly richer, deeper bass performance.

Precision Crossover: To seamlessly blend the audio output from the high frequency driver (tweeter) and the two midbass drivers (woofer), the Motion 30 loudspeaker features a precision crossover utilizing custom air core coil and low DCR steel laminate inductors, polyester film capacitors in series, and low DF electrolytic capacitors in parallel.

High-Gloss Cabinet: Complementing the Motion 30 loudspeaker's sonic accuracy is its elegant, yet understated styling. A high-gloss, piano black or black cherrywood finish, along with MartinLogan's signature perforated grille, give the Motion 30 speaker an elegant and timeless look that will blend into almost any decor. The speaker cabinet also features smooth, rounded edges.

Binding Posts: MartinLogan's proprietary tool-less binding posts simplify cable connection and management. The binding posts will accept bare wire (16- to 10-gauge), pin-connectors, spade-connectors, and banana plugs (single only).

Placement: The MartinLogan Motion 30 should be centered below or above your television on flat-surface; such as a table-top, stand, cabinet, or shelf. The center channel speaker comes with 4 rubber self-adhesive feet to help secure it in place, prevent slippage, and reduce vibration.

Break-in Period: Allow approximately 72 hours of break-in at 90 dB (moderate listening levels) before any critical listening.

Solid Center Channel Speaker

Written By PeterS, Atlanta, GA on Sunday, August 17, 2014
Crutchfield Customer Review (What's this?)
Excellent center channel spear. Clear crisp dialogue blends well to create a good family room moving watching experience.
Sound quality and build quality are both very good
Maybe a little too deep to fit perfectly on some mantles (which is probably the dominate installation spot for this speaker.)

Great sound quality

Written By Jim, Baton Rouge, LA on Tuesday, July 22, 2014
Crutchfield Customer Review (What's this?)
Very good sound quality. Have it hooked up with a Marantz receiver, ML Motion 40 and ML's in the back and ML sub. Spent more than planned, but needed the range and quality that this speaker delivers. Considered the Motion 8 until I tested this one. Looks good too. Very happy with decision.
Sound quality, highs, mids and lows....great pressence for a center channel.

Motion 30 Center Channel

Written By shootshescores, Detroit, MI on Tuesday, June 17, 2014
Crutchfield Customer Review (What's this?)
This is an exceptional center channel speaker and a great additional to my new home theater system. The binding posts are unique, very robust, and easy to use. The gloss finish of the cabinet gives a great high end look. The magnetic grill cover is very well made and fits great. The 3 drivers installed in the cabinet all handle difference frequencies. The internal crossover sends the highs to the folded ribbon tweeter, the driver on the left handles the midrange, and the driver on the right handles the low frequencies. Dialogue in movies and television is crystal clear. Music even sounds great. The folded motion tweeter sounds crystal clear and bright without being overwhelming or growing tiresome of the highs. My Audyssey set the center speaker as large and currently passes all frequencies down to 40hz to the speaker. I was surprised at this setting, but it just performs no matter what crossover setting I throw at it. Even at full range it sounds great. The Motion 30 replaced my old Bose VCS-10 and there is really no comparison between the two. The only analogy I can provide is that the Bose sounds like an 80's alarm clock compared to the Martin Logan Motion 30 center channel speaker.
