MartinLogan Motion XTC8-HT In-Ceiling Speaker

The "HT" version of the XTC8 features a fixed angle mounting of the tweeter and woofer to provide a dramatic performance boost for listeners who are further away. This is the perfect choice when a speaker needs to be mounted far away from where the listener will be standing, walking or sitting, such as in a home theater. When used as a front or center speaker in a home theater, the listener is typically about 10 feet or more away, but typical in-ceiling speakers fire straight down placing the sweet spot directly in front of the screen. By angling the drivers toward the listener, a very noticeable increase in performance is achieved. The same is true for whole-house music systems where speakers are often placed farther away from where the listener spends the most time. In situations like this, the angled “HT” models provide a very real and very noticeable increase in performance.

MartinLogan’s Motion XT CI Series takes performance to the next level over the Motion CI. The Folded Motion XT tweeter gives every Motion XT Series model even more of the clarity, power, and efficiency the full-size FMT model is known for. With the Motion XT, we wanted to elevate every aspect of performance over the Motion Series, so we didn’t just stop at the tweeter. All Motion XT models feature woven Kevlar woofers for increased rigidity and light weight, as well as a special Nomex layer on the backside of the woofer material that increases clarity and realism while reducing resonance and reverberation. In addition to the larger tweeter and lighter, stronger woofers, MartinLogan’s design and engineering team gave the Motion XT Series a more substantial chassis to strengthen the driver and deliver a more accurate sound, similar to a better cabinet on a traditional loudspeaker. The Nomex layer and chassis are not something you can see after installation, but they are important to the performance of the speaker, so they are important to us. With Motion XT CI, the difference is in the details.

The Sound of Invisibility: Folded Motion ® Tweeter

MartinLogan's Folded Motion tweeter uses an extremely low-mass diaphragm that "squeezes" air, requiring significantly less excursion than the typical 1-inch dome tweeter. Its folded design allows for a much larger surface area (compared to that of a typical 1-inch dome tweeter), controlled dispersion characteristics, and incredibly low distortion. It is a marvel of audio engineering, delivering much of the high-frequency detail, speed, and response of a large dynamic electrostatic panel in a smaller space. Folded Motion XT tweeters further advance thin-film transducer technology with a 40 percent larger radiating surface and controlled 80 x 30-degree dispersion. This upgrade increases audible bandwidth without sacrificing detail and reduces distortion to an incredibly low level while increasing the tweeter's efficiency and already lightning-fast response time. The result is superior realism and alarming specificity that is aurally astonishing, and only from MartinLogan.

This thin-film transducer design packs all the precision and subtlety of an electrostatic panel into a smaller space. Folding the incredibly lightweight film into an accordion-like structure increases surface area, giving Folded Motion tweeters eight to 10 times more surface area than typical tweeters. This ideal combination of light weight and size produces superior precision, extended frequency bandwidth, and increased output capacity; all with faster, more efficient transient response and virtually zero distortion. In these features, the Folded Motion tweeter design can mimic the performance of a large electrostatic panel within the constraints of a more traditional speaker enclosure.

Braided Kevlar Cones

All Motion XT CI speakers feature lightweight woven Kevlar cones, specifically designed to keep up with the lightning-fast performance of our highest-performance XT Folded Motion Tweeter. While these high-performance drivers offer both increased rigidity and light weight, we took it a step further by adding a special Nomex layer to the back side of the woofer material that increases clarity and realism while reducing resonance and reverberation. This layer isn't something you can see after installation, but it's important to the speaker's performance, so it's important to us.

No matter which Motion XT CI speaker you choose for your room, you can rest assured that they are designed to deliver a consistently high level of performance and can be easily paired with other MartinLogan speakers to make it that much easier to create the perfect system for your unique listening space.

The MartinLogan Sound

MartinLogan Motion XT CI speakers sound incredible in any room. Regardless of the environment, our speakers sound better, more articulate, more detailed, and more lifelike. With controlled dispersion and one of the most responsive tweeters in the industry, our in-wall and in-ceiling models can compete with and often exceed the performance of traditional cabinet speakers.

Spring Binding Posts

Featuring easy pre-installation access, our spring binding posts feature a large access hole for 4.5 mm wire and connect via banana plug, pin, or bare 12 AWG wire.

Micro-Perforated Grilles

All MartinLogan architectural speakers feature ultra-low-profile, paintable, micro-perforated grilles with no visible bezel for nearly invisible integration into any wall or ceiling. A series of powerful magnets hidden inside the speaker quickly secure the grilles in place, reducing the risk of warping or damage during installation. Optional square grilles are available for all current MartinLogan in-ceiling speakers.

Proprietary Vojtko™ Crossover Networks Vojtko crossovers are named after MartinLogan's chief audio engineer, Joe Vojtko.

His unique approach to crossover design is as crucial to MartinLogan's Truth in Sound as are our innovative electrostatic and Folded Motion thin-film driver technologies. A Vojtko crossover isn't just a set of design requirements; it's a philosophy.

Vojtko crossovers are hand-built from the highest-quality components and avoid overly complex topologies. This crossover has one simple goal: breathtaking realism.

Hand-Selected Components

In designing each crossover topology, we take the drivers themselves into consideration. Carefully selected drivers, designed for specific performance characteristics, are held within their optimal frequency range by the custom Vojtko crossover.

Each crossover is handcrafted using exceptional polypropylene and polyester capacitors, large custom-wound, steel-laminated low-DCR inductors, and double-thickness PCBs. This precisely tuned network preserves even the most microscopic sonic nuances while handling the full dynamics of any source. It's a recipe for incredibly low distortion and seamless driver integration.

The most critical aspect of a Vojtko Crossover design is the final voicing, always conducted in a real-world environment. This unique, pragmatic approach ensures that even the most stunning MartinLogan speakers deliver Truth in Sound to any room, including yours.

Optional Retrofit Enclosure

All Motion CI in-ceiling speakers have the option of a rear enclosure or retrofittable enclosure. This helps contain the sound coming from the back of the speaker to dramatically reduce unwanted sounds that can travel through the floor and into the living space above the speaker. For those wanting more bass output or when sound control is not required, you can simply choose to use the MC8 without the optional enclosure so that it can take full advantage of the larger air volume provided by the ceiling space.
