MartinLogan Motion XT F200 Tower and Motion XT C100 Review
Table of contents
Since its debut in 2009, the MartinLogan Motion series has been a reliable choice for audio enthusiasts. Over the years, while retaining the well-recognized name, the line has seen numerous changes. With the unveiling of the MartinLogan Motion XT line of speakers, specifically the XT F200s, it's clear that the series has taken a big leap forward, turning into something distinctly different from its original iterations.
The Motion XT series sits as the flagship of three new Motion lines and includes two floor-standing models, a center-channel speaker, and a bookshelf speaker, each priced as follows:
- Motion XT F200: $2,750 each
- Motion XT F100: $2,250 each
- Motion XT C100: $1,500 each
- Motion XT B100: $800 each
The new Motion series also includes the intermediate “Motion” line which falls between the entry-level "Motion Foundation” and “XT” series. This middle tier offers a selection of two towers, one bookshelf, one multipurpose speaker, and one center channel. The models are priced as follows: the F20 tower at $1,749.99 each, the F10 tower at $1,249.99 each, the B10 bookshelf at $599.99 each, the C10 center channel at $999.99 each, and the MP10 multi purpose speaker at $499.99 each.
In this review, the focus is on two prominent models from the Motion XT Series: the XT F200, which is the flagship model, and the C100 center channel. The XT F200 is a three-way floor-standing speaker featuring a frequency response range of 27 Hz - 25k Hz ±3 dB. It comes with a sensitivity rating of 92dB and an impedance of 4 ohms.
Specifications
Starting at the top of the speaker, the tweeter has undergone some significant changes. It now features a 1.25-inch by 2.4-inch Gen2 Obsidian Folded Motion Tweeter, which boasts an approximately 40% larger surface area compared to its standard counterpart. This updated tweeter also benefits from new, larger magnet structures that contribute to reduced distortion and enhanced output. The speaker incorporates proprietary Folded Motion Waveguides to improve tweeter dispersion. Specifically, the Motion XT waveguide is designed with a 45-degree vertical by 90-degree horizontal orientation.
In the midrange section, the speaker incorporates a 6.5-inch driver, a big upgrade in this particular line. The midrange driver is built with Nomex Reinforced Kevlar cones and is housed in its own sealed chamber.
As for the lower section, the speaker is fitted with three 8-inch aluminum cone-based drivers. Unlike in many traditional tower speakers, these drivers are positioned closer to the floor. This placement takes advantage of floor bounce to reinforce and enrich the low-end frequencies.
The design of the F200's drivers is port-tuned, but you won't see any ports on the back of the speaker. Instead, you'll find dual sets of high-quality five-way binding posts, which are connected by a removable jumper bar for optional bi-amping or bi-wiring. MartinLogan has opted for a down-firing system, known as the Cannon Port, which vents through twin openings at the speaker's base. This makes the sizable cabinet a bit easier to handle during the setup process.
Turning our attention to the C100 center channel, this model boasts a pair of 6.5-inch mid-bass drivers constructed from Nomex-Reinforced Kevlar, each set within its own non-resonant sealed chamber. It also features a Gen2 Obsidian FMT XT Tweeter, further refined by a Folded Motion Waveguide. This speaker features an unique 2.5-way crossover design aimed at reducing lobing effects while maintaining the original tonality of the source material. In essence, it offers the bass output similar to a 3-way speaker while avoiding the lobing drawbacks commonly associated with 2-way speakers, all within a more compact form factor.
In configurations like those seen in the C100, C10, and C1 models, the 2.5-way MTM (Midrange/Tweeter/Midrange) design comes into play. Both woofers operate identically up to the lower crossover point. After that, one woofer rolls off while the other continues up to the tweeter's crossover point. This approach effectively minimizes lobing in much the same way as a traditional TM (Tweeter/Mid) design would, providing the benefits of a 3-way system without requiring the additional height.
In terms of technical specifications, the C100 has a sensitivity of 93dB and an impedance of 5 ohms. Its frequency response spans from 42 Hz to 25 kHz ±3 dB. The tweeter's dispersion pattern expands to a 90° x 45° angle. A noteworthy feature is the speaker's flippable cabinet design, which enhances sound directionality. When situated on a lower shelf or furniture piece, the cabinet can be flipped to channel sound upwards, improving clarity and listener immersion.
Design
The Motion XT F200 and C100 are available in three finishes: gloss black, satin white, and walnut. For the purposes of this review, I opted for the gloss black finish to complement my existing setup. I must say, the speakers are visually striking. The gloss black exterior exudes a premium aesthetic, complemented by a front baffle in a more subdued matte black. While I personally find the exposed drivers appealing, these speakers also include individual round grilles that attach with a hidden mounting tab, if you prefer a covered look. The company has designed the grille with a hidden retention system behind the trim ring, making it cosmetically invisible.
Located at the base of the XT F200 speakers, MartinLogan has incorporated their F.A.S.T (Fully Adjustable Spiked Toolless) feet, which are the most well-designed feet I've encountered. They can be easily adjusted by hand and feature interchangeable tips: you can choose between metal points for carpeted surfaces or rubber tips that are hardwood-floor friendly. As for the specifications, the tower speakers have a large footprint, weighing 86 pounds and measuring 50.75" x 13.75" x 16.5". The center channel is lighter but still solid, with a weight of 34 pounds and dimensions of 8" x 24" x 14.5".
Setup
I positioned the speakers in my standard listening area, setting them about eight feet apart and roughly eleven feet from my main listening position. They were also about a foot and a half away from the front wall and slightly toed in. The Motion XT F200's bottom ports make speaker placement more forgiving. Unlike rear-ported speakers, where the distance between the port and the wall can vary and affect sound quality, these ports maintain a consistent distance from the floor.
For the audio setup, I used a Trinnov Altitude16 processor, powered by a Trinnov Amplitude16 amplifier, with a Kaleidescape serving as the source material. I experimented with room correction both on and off, ultimately favoring the performance offered by the room correction with these particular speakers.
MartinLogan recommends a 72-hour break-in period at what they describe as moderate listening volumes, set at 90dB. While the concept of speaker break-in remains a topic of debate, I found the bass significantly improved after following the 72-hour recommendation. Although the bass was present initially, it became more pronounced and full-bodied after the break-in period.
MartinLogan also provided a Dynamo 1100X subwoofer for this review, which you can read more about here. I found the bass output from the XT F200 speakers to be pretty good on its own during two-channel and low-volume movie listening, but coupling the XT F200s with the Dynamo 1100X significantly enhanced the lower-end extension, adding to the bass response that truly elevated the overall experience.
Performance
While watching "Top Gun: Maverick," the performance of the XT F200 and C100 speakers is impressive from the get-go. In high-octane scenes like the aerial dogfights, the bass impact is palpable. The speakers deliver the low-frequency roars of the fighter jets with a visceral, engaging strength, due in part to those three 8-inch woofers.
The midrange also stands out, offering a neutral character. Dialogue clarity is exceptional, thanks largely to the C100 center channel. During quieter scenes or intense dialogue exchanges, every word comes across as intelligible and distinct. For example, in debriefing scenes or when characters engage in one-on-one conversations, the nuanced inflections in their voices are clearly discernible. This clarity is maintained even when the dialogue competes with powerful background scores or ambient noise.
During another action-packed movie, "Mad Max: Fury Road," the expansive soundstage of the XT F200 and C100 speakers is immediately apparent, especially during the high-speed chase scenes through the desert. The dynamics of these speakers are striking; the roar of engines, screech of tires, and blast of explosions envelop the room in a way that places you right in the heart of the action. One particularly memorable scene is the wild War Rig chase, where the speakers expertly handle all the sounds from multiple directions.
The tweeter shines in its delivery of high frequencies, capturing the subtlest details like the weapons hitting the cars and the high-pitched wail of the electric guitar. The highs are lively and forward without ever tipping into harshness, rounding out a sonic experience that's as detailed as it is expansive.
Even at my regular listening volume, which typically hovers around 80-85dB with peaks at 95-100dB, these speakers maintain near-perfect clarity without any harshness. Pushing the envelope, I cautiously ramped up the volume to highs nearing 110dB, and remarkably, the sound remained crisp and articulate.
Listening to "Barracuda" by Heart on the XT F200 speakers is a revelation in two-channel audio fidelity. The control these speakers offer is immediately evident, especially in the taut, rapid-fire guitar riffs that open the song. Each pluck of the string is sharply defined, yet blends smoothly into the overall musical landscape. The drum kicks and bass guitar are impactful but never overwhelming, revealing the speakers' excellent low-frequency control.
What's truly impressive is the center image; the vocals of Ann Wilson are placed dead-center between the speakers with astounding clarity and presence, making it feel as if she's performing live in the room. The vocal harmonies and nuances in her powerful voice come through beautifully, lending emotional weight to the song's already impactful lyrics. The stereo separation is excellent, allowing each instrument its own space within the mix while contributing to a cohesive whole. This makes for an immersive listening experience where the song's complexities are laid bare, and the talents of the musicians are fully appreciated.
Conclusion
The MartinLogan XT F200 and C100 speakers are a formidable pairing that delivers on multiple fronts. The mids and highs demonstrate sheer power and finesse without ever bordering on harshness, delivering an audio experience that's both enveloping and precise. While there are certainly more expensive options on the market, these speakers make a compelling case that you simply don't need to look further.
They offer everything you could ask for in a high-quality audio setup. While they may not be considered inexpensive, they deliver a performance that, in my opinion, surpasses their price point, sounding like speakers that should cost considerably more.

FAQ
Are 8-ohm speakers easier to drive than 4 ohm?
Yes, 8-ohm speakers are generally easier to drive than 4-ohm speakers. An 8-ohm impedance allows for less current to flow through the amplifier, reducing the demand on the amplifier's output circuitry. This is why many consumer-grade amplifiers are optimized for 8-ohm speakers. On the other hand, 4-ohm speakers allow more current to flow, which can potentially lead to overheating if the amplifier is not designed to handle such loads.
What is the difference between 2-way and 3-way speakers?
A 2-way speaker consists of two kinds of drivers: a woofer for low frequencies and a tweeter for high frequencies. In contrast, a 3-way speaker produces sound using three separate components: mid-range, woofer, and tweeter drivers.
What are the benefits of 3-way speakers?
The benefits of a 3-way speaker system encompass enhanced audio clarity, an expanded soundstage, and better bass performance. By having dedicated components for high, mid, and low frequencies, the system can more precisely and clearly reproduce each frequency range.
