Folded Motion XT tweeter for superior detail

MartinLogan 50XT center channel speaker

MartinLogan's most advanced Folded Motion XT tweeter produces clear, detailed highs.

MartinLogan's innovative Folded Motion XT tweeter uses a pleated diaphragm that works similarly to an accordion by "squeezing" air to create sound. Because it requires almost 90% less excursion than the typical 1" dome tweeter, response time is drastically reduced along with distortion. The diaphragm's increased surface area also provides wide, yet controlled sound dispersion to create a realistic and highly accurate soundstage. Movie and TV dialogue sound detailed, but smooth and effortless, without a trace of harshness. And the XT tweeter boasts a 40% larger radiating surface area than the standard Folded Motion tweeter found in other MartinLogan designs, for even greater bandwidth and efficiency.

Bass that keeps pace

The Motion 50XT uses dual 6-1/2" aluminum cone woofers to supply fast, clean midrange and powerful low 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.

Beautiful cabinet with an angled design

With its flawless Piano Black or Black Cherrywood high-gloss finish, gently radiused corners, and handsome perforated magnetic steel grille, the 50XT is one beautiful center channel speaker. Its angled enclosure is also 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 out into the room.

Cons: none.

MartinLogan Motion® 50XT

Crutchfield customer from Hollywood, FL on 8/31/2018

Crutchfield Customer Review (What's this?)

Great center channel speaker. I paired it with the Motion 40 tower speakers and it does a great job. Beware, it's got a lot of bass due to its dual 6.5 woofers. They are still within the break-in period and I'm confident they will sound even better with time.

Pros: -Sound -Quality & Finish

Cons: -Price (but you get what you paid for)

Smooth and powerful!

Andy from Colorado Springs, CO on 8/15/2018

Crutchfield Customer Review (What's this?)

I absolutely love it! I've got some JBL T100's and have had a lot of trial and error trying to get a speaker that would keep up with them. I purchased Klipsch and other supposedly good sounding speakers to no avail. I purchased a heavier duty Denon receiver. That didn't do it. Finally! I got this MartinLogan center channel speaker and absolutely love it

Pros: Simply an incredible speaker after many other tries!

Cons: Non!

Set the foundation for your HT!!

Julius from Davenport, IA on 5/26/2018

Matched to Motion 40 towers for front stage knowing it can can handle whatever is thrown at it.

Pros: No worries about it handling any audio from any source!

Cons: .....................

Crystal clear sound

Jeffrey from Millbury, MA on 3/30/2018

Crutchfield Customer Review (What's this?)

Clear sound even at high volumes. Keeps up with the rest of the setup nicely.



The Ribbon tweeter

MARK from Connecticut on 1/5/2018

Crutchfield Customer Review (What's this?)

I was drawn to this center channel due to its well regarded ribbon tweeter. Overall it has a bold, vibrant sound and gives a very large sense of scale, but for me the voices and dialogue could have been clearer.

Pros: Nice sparkle to the highs Not shy with its bass Balanced sound

Cons: Dialogue tended to get a bit lost in scenes with a lot of action effects Gloss black finish scratches way too easily, passing clean fingers over the finish took paint off


Crutchfield customer from Claremont, NC on 12/26/2017

Pros: Everything

Cons: Nothing

Jerry from Houston, TX on 10/3/2017

Crutchfield Customer Review (What's this?)

I purchased the Motion 50XT to upgrade a 14-year-old Boston Acoustics center channel. The increase in the bass and the overall clarity was much better than I had expected. Voices are exceptionally clear. The overall sound is very detailed. Highly recommended.

Pros: Excellent clarity Black Cherrywood is beautiful

Cons: None

Motion® 50XT

Brett from Bozrah, CT on 9/10/2017

Crutchfield Customer Review (What's this?)

I added this to replace a Polk LSiC center channel. The 50XT is a great addition to any home entertainment system. Much more vibrant and realistic sound than the Polk. Eager to add more MartinLogan speakers to my setup.

Pros: Clarity Crisp Sound Overall realistic sound

Cons: Price

Clean, Clear, Bold Center

Terry from Virginia Beach, VA on 2/20/2017

Crutchfield Customer Review (What's this?)

Clean, Clear and bold. I am still in the breaking in period as recommended by Martin Logan. I listened to both the Motion 30 which is great as well but the emphasis I wanted from a center came from the 50xt. It fit in my media center. Martin Logan as well as crutchfield provided quick and appropriate information for me to make the purchase . I was looking at B&W, Def Tech, and Martin Logan. The size of the 1st two would not work well with my furniture. No complaints with the sound from the B&W at all but the size was to big. Great center from the 50 XT and it is an awesome speaker. Very pleased thus far in my ongoing evaluation.

Pros: perfect fit for my situation and the performance is the best

Cons: none

Pros: Look fantastic Excellent delivery from ML What you expect when investing $$$ in center speaker - but well worth money

Cons: None


Rick H from Illinois on 5/30/2015

Crutchfield Customer Review (What's this?)

Excellent sound. I changed speaker without telling wife. That evening while watching a movie she commented on the sound within two minutes. It was that much of a difference from my old Cambridge 3 way, which was good at the time.

Pros: Excellent movie theater sound in large room gloss black looks rich Noticeable difference in sound

Cons: none

Product Research


2.5-Way Center-Channel Loudspeaker: The MartinLogan Motion 50XT center-channel loudspeaker employs a 2.5-way speaker design and features MartinLogan's advanced resolution Folded Motion XT tweeter and dual 6.5" aluminum cone midbass woofers. Combining these three drivers together creates a dynamic full-range sound with an expansive soundstage.

  • Folded Motion Tweeter: MartinLogan's Folded Motion XT tweeter helps give the Motion 50XT 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 1.25" x 2.4" Folded Motion XT 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°x30°) to create a realistic and carefully etched sound stage.
  • Dual Aluminum Cone Woofers w/ Bass Port: The MartinLogan Motion 50XT center-channel loudspeaker features two high-excursion 6.5" aluminum cone woofers with a cast basket housed in a non-resonant asymmetrical chamber with a rear-firing bass port. The aluminum cone woofers use a rigid structured dust cap to reduce cone break-up and distortion. Pairing dual 6.5" woofers with a rear-firing bass port provides 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 50XT loudspeaker features a precision crossover (900Hz/2.2kHz) 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 MDF Cabinet: Complementing the Motion 50XT loudspeaker's sonic accuracy is its solidly constructed 3/4" thick MDF cabinet. The cabinet is finished in either high-gloss piano black or black cherrywood, and includes MartinLogan's signature perforated grille. The Motion 50XT speaker's elegant and timeless look will blend into almost any decor. The speaker cabinet also features rounded edges and a gently tapered top.

Bi-Wiring/Bi-Amping: Using the dual posts, you can bi-wire or bi-amp the speaker. Bi-wiring or bi-amping the speaker provides improved bass & treble performance. If you decide to bi-wire or bi-amp, you must remove the jumpers between the terminal posts (failure to do this could result in damage to your amplifier and loudspeakers).

  • Bi-Wiring: Bi-wiring can provide noticeable improvements in the overall transparency of your loudspeakers. Run separate speaker wires to the low & high frequency drivers from a single amplifier (the upper set of binding posts are for the high frequency drivers; the lower set of binding posts are for the low frequency drivers).
  • Bi-Amping: Bi-amping allows you to use separate amplifiers for the high & low frequency sections of your loudspeaker for greater dynamic range & lower distortion. We recommend that your separate amplifiers have identical gain to preserve the speaker's voicing balance.
Note: 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 50XT 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 four 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.

I have owned an entire array of MartinLogan speakers for the last 12 years and have been extremely pleased with their performance, especially of classical music.
