MartinLogan, renowned for its high-end floorstanding speakers (often electrostatic), aims to bring the performance of those speakers to a different market. They’ve done this by completely reimagining their Motion Series catalog of floorstanding and audiophile bookshelf speakers, and putting the speakers through a rigorous development process that included anechoic chamber measurements, blind listening tests and in-room measurements.
The MartinLogan Motion XT B100 (buy at Crutchfield) are not the least expensive small speakers out there at $1,600, but they bring the open sound of an AMT tweeter to small spaces without having larger, electrostatic panels in the room. They are less directional, thus easier to place in any given room. They fit on a shelf, or equally well on a stand. The MartinLogan Motion XT B100s aren’t the only stand-mount or bookshelf speakers in the market with an AMT tweeter, but they do come with the MartinLogan lineage and history. Can they live up to that level of hype? That’s what we are looking for in this review. Let’s get started …
What Makes the MartinLogan Motion XT B100 Bookshelf Speakers Special?
- The Folded Motion technology used in the tweeter of the MartinLogan Motion Series is exotic and unique compared to traditional tweeters. The design, reminiscent of an accordion, moves air perpendicular to the folded diaphragm’s ridges, resulting in lightning-fast transient response and a large surface area eight to 10 times greater than a typical one-inch dome tweeter. This unique configuration minimizes distortion and enhances sound clarity, creating a dynamic and precise audio experience. The use of neodymium iron boron magnets in the tweeter provides superior control and efficiency, ensuring low distortion and high precision. Although the Folded Motion technology alone cannot produce deep bass, the speakers seamlessly integrate high-quality dynamic woofers to deliver a balanced and detailed sound across all frequencies.
- The Gen2 Obsidian Folded Motion XT tweeter used in the XT B100 provides a vibrant, clean and detailed high end . MartinLogan has upgraded the tweeter with a larger motor to provide higher output and lower distortion, and this specific speaker comes equipped with the XT, which offers a 40 percent increase in surface area over the regular folded motion tweeter.
- A notable feature of the MartinLogan Motion XT B100 Bookshelf speakers is their use of a Nomex-Reinforced Kevlar midrange driver, which plays a crucial role in delivering detailed and accurate sound. This midrange driver is constructed from a combination of Nomex and Kevlar fibers, materials known for their exceptional strength and rigidity. This unique blend allows the driver to produce clear and precise midrange frequencies while minimizing distortion and unwanted resonances. The rigidity of Kevlar ensures that the driver maintains its shape even under high stress, while Nomex enhances its damping properties, resulting in a smooth and natural sound reproduction.
- The MartinLogan Motion XT B100 Bookshelf speakers have a clean, modern aesthetic.The sleek, minimalist cabinet design features elegant lines and high-quality finishes that can blend in with any home decor. The attention to detail is evident in every aspect of the speaker’s appearance, from the precisely crafted edges to the seamless integration of the wave guide and drivers into the front baffle. The lack of visible screws and the refined grille design further enhance the sophisticated look, giving the speakers a polished and unobtrusive presence. I was shipped the white version, but the dark version with a walnut veneer cabinet and gold accents is equally as beautiful. This careful consideration of aesthetics ensures that the Motion XT B100 speakers are as pleasing to the eye as they are to the ear, making them a stylish addition to any living space while delivering an exceptional audio experience.
Why Should You Care About the MartinLogan Motion XT B100 Bookshelf Speakers?
The MartinLogan Motion XT B100 Bookshelf Speaker deserves attention for several key reasons. First, its use of exotic driver technology, particularly the Folded Motion tweeter and the Nomex-Reinforced Kevlar midrange driver, sets it apart from many competitors. These advanced components provide a highly accurate and dynamic sound, ensuring that every nuance in the music is captured with clarity. Compared to previous generations, the XT B100 boasts significant improvements in both sound quality and design. The enhancements in driver technology have led to better transient response and lower distortion, making these speakers a true upgrade for those familiar with MartinLogan’s older models. Additionally, the solid aesthetics of the XT B100 can’t be overlooked. Its sleek, modern design integrates seamlessly into any home decor, offering a clean look that compliments its high-performance audio capabilities. For anyone seeking a blend of cutting-edge audio technology and stylish design, the MartinLogan Motion XT B100 is a speaker worth considering.
Some Things You Might Not Like About the MartinLogan Motion XT B100 Bookshelf Speakers
- The Folded Motion tweeter in the XT B100 really is the star of the show here, and it seems MartinLogan may have given it a slight boost in the high frequencies to highlight the technology’s fantastic performance. This may lead to the highs being a little too lively for some listening settings. However, in my treated room, I’ve been able to create a neutral and pleasing sound profile.
- One aspect to consider with the MartinLogan Motion XT B100 Bookshelf Speaker is its relatively narrow horizontal sweet spot. While the Folded Motion tweeter provides exceptional clarity and detail, it also means that the optimal listening experience is somewhat confined to a specific area directly in front of the speakers, as you might find to a larger extent with more traditional electrostatic speakers like, say, the much more restrictive (in terms of imaging flexibility) MartinLogan ElectroMotion ESL speakers (buy at Crutchfield). As you move off to the sides, the sound quality can diminish, leading to a less immersive experience for those not seated in the ideal spot. This limitation might be a concern for larger rooms or settings where multiple listeners are spread out, but for a dedicated listening space with strategically-placed seating, the focused sweet spot can deliver an incredibly precise and engaging audio experience.
Listening to the MartinLogan Motion XT B100 Bookshelf Speakers
To put these speakers to the test, I integrated them into my existing audiophile system. My setup includes a ROON core as the source, connected to a Topping E30 DAC, and then to my reliable Yamaha AS301 Class-AB integrated amp. For room treatment, I have two-inch-thick GIK Acoustics panels at all first-reflection points, along with a four-inch GIK bass trap. I positioned the speakers about two-and-a-half feet from the back wall and toed them in towards the listening position, which is near the center of the room.
For my first comparison, I am going to be listening to Joe Hisaishi’s album “A Symphonic Celebration.” Besides being a fantastic new recording of his most iconic works, beautifully orchestrated and performed by the Royal Philharmonic Orchestra, I chose it because this weekend I had the pleasure of listening to Hisaishi conducting the Chicago Symphony Orchestra live at the Symphony Center. The highs delivered by the MartinLogan XT B100 were particularly impressive. The Folded Motion tweeter excelled in bringing an incredible amount of detail and sparkle to the upper registers. Whether it was the shimmering cymbals, the crisp violin strokes, or the airy flute passages, the highs were rendered with astonishing clarity and realism. The tweeter’s ability to handle fast transients with ease meant that even the most complex passages were conveyed with precision, making the listening experience both engaging and lifelike.
Moving to the mids, the performance remained strong, though not quite as standout as the highs. The Nomex-reinforced Kevlar midrange driver provided a natural and balanced sound, ensuring that the critical midrange frequencies were clear and detailed. The rich timbres of the woodwinds, the warmth of the brass, and the fullness of the strings were all well represented. The woofers offered a very good performance, maintaining coherence and musicality throughout.
When it came to the lows, the XT B100 stretched relatively low for its size, thanks to its well-designed woofer. The bass was tight and controlled, providing a solid foundation for the music. However, due to the physical limitations of the driver size, the lowest frequencies lacked the deep, visceral impact that larger speakers or subwoofers can deliver. Despite this, the bass performance was commendable for a bookshelf speaker, with sufficient depth and punch to support the orchestral arrangements effectively.
The soundstage and imaging of the MartinLogan XT B100 were other areas where the speaker truly shone. The speakers created a wide and immersive soundstage, making it easy to visualize the placement of each instrument within the orchestra. The imaging was precise, with a clear sense of depth and separation between the different sections of the ensemble. This quality made the listening experience feel more three-dimensional and lifelike, enhancing the overall enjoyment of the album.
Comparing this experience to my weekend listening to Hisaishi conduct the Chicago Symphony Orchestra, the XT B100 delivered an incredible sound that closely captured the essence of the live performance. The strings and brass were especially beautifully rendered, with the speakers managing to convey the emotion and energy of the live event. While the live concert had an unmatched sense of presence and immediacy, the XT B100 provided a remarkably faithful reproduction of the music, bringing the concert hall into my listening room. The speakers’ ability to handle the intricate details and dynamic range of Hisaishi’s compositions made the album come alive, almost transporting me back to that unforgettable evening with the CSO.
To further evaluate the MartinLogan Motion XT B100 Bookshelf Speakers, I decided to switch genres and listen to “Dreams” by Fleetwood Mac. This classic rock track features a blend of Stevie Nicks’ ethereal vocals, layered harmonies, and a rhythm section that is both tight and dynamic. The XT B100s handled the song beautifully, highlighting the intricate guitar work and the shimmering quality of Nicks’ voice. The highs were crystal clear without being harsh, allowing the cymbals and high-hat to shine through the mix. The speakers’ ability to articulate the finer details of the song added a layer of depth that enhanced the listening experience. You can listen to the song here.
The midrange performance was equally impressive, capturing the warmth and fullness of the vocal harmonies and the rich, woody tones of the acoustic guitars. John McVie’s bass lines were well-defined and provided a solid foundation, without overwhelming the other elements of the mix. While the speakers did a commendable job with the bass, they remained true to their bookshelf design, delivering a tight and controlled low end that complimented the mids and highs rather than overpowering them. The soundstage was expansive, with excellent imaging that made it easy to place each instrument within the mix. Overall, the XT B100s delivered a balanced and engaging reproduction of “Dreams,” proving their versatility across different musical genres.
