MartinLogan Motion 40i Review and Overview
The MartinLogan Motion 40i is a floor-standing loudspeaker designed as a core component for a high-performance stereo or home theater system. Its main purpose is to offer a taste of MartinLogan’s renowned electrostatic clarity in a more conventional and accessible dynamic driver package. This speaker is engineered for the discerning listener who appreciates fine details, spatial accuracy, and a lively, dynamic presentation across all types of media, from music to movies.
This product is ideally designed for the music enthusiast or home cinema fan who is ready to invest in a significant audio upgrade. The target audience values accuracy and refinement over sheer, overwhelming power. Key specifications include a Folded Motion XT tweeter, dual 6.5-inch aluminum woofers, and a recommended power handling of 20-300 watts. The speakers are moderately sensitive, making them compatible with a wide range of amplifiers, though they truly shine with quality electronics.

Key Features & Performance
In my testing, the performance of the Motion 40i is a direct result of its thoughtful engineering. The combination of its key features creates a cohesive and impressive sonic signature that sets it apart from many competitors in its class. The real-world usability is straightforward, though I recommend giving them some space to breathe from rear and side walls to achieve the best soundstage.
Folded Motion XT Tweeter
The heart of the MartinLogan sound is the Folded Motion tweeter. Unlike a typical dome tweeter, this design features a diaphragm that is pleated and moves like an accordion. This results in a radiating surface that is much larger than a dome, yet with far less physical travel. The outcome is stunning high-frequency reproduction that is incredibly detailed, smooth, and disperses sound widely throughout the room. I noticed cymbal crashes had a delicate shimmer and string instruments possessed a lifelike texture without ever becoming harsh or fatiguing.
Dual 6.5-Inch Aluminum Woofers
Handling the midrange and bass are two rigid 6.5-inch aluminum cone woofers. These drivers provide a solid foundation, delivering punchy and articulate bass that is tight rather than boomy. In my experience, they integrated seamlessly with the tweeter, creating a coherent sound from the lowest notes up through the vocal range. While they won’t replace a dedicated subwoofer for home theater enthusiasts craving subterranean effects, they produce a remarkably full-range sound that is satisfying for most music genres.
Precision-Crafted Cabinet
The cabinet itself is a feature. It feels incredibly inert and solid, with internal bracing to minimize unwanted resonance. This attention to construction means that the sound you hear is coming from the drivers, not from a vibrating box. The non-resonating Medite cabinet and the elegant, low-diffraction magnetic grille all contribute to a cleaner, more accurate sound. Aesthetically, the clean lines and optional magnetic grilles give them a sophisticated look that avoids the “big black box” appearance of some speakers.
Integrated Vojtko Koer Binding Posts
While it may seem like a small detail, the high-quality binding posts are a welcome touch. They are massive and allow for a secure connection with various types of speaker cables, including spade connectors, which are often preferred by enthusiasts. This ensures that the signal from your amplifier is transferred to the speakers with the highest possible integrity, leaving no weak link in the audio chain.

Final Verdict
After a thorough evaluation, the MartinLogan Motion 40i earns a strong recommendation for the right user. They are not a one-size-fits-all speaker, but for those who prioritize clarity, soundstage, and build quality, they are an outstanding choice. Their performance is a testament to MartinLogan’s engineering philosophy, bringing high-end characteristics to a more accessible price point.
Pros
- The Folded Motion tweeter delivers unparalleled clarity and a spacious soundstage.
- Excellent build quality with a beautiful, furniture-grade finish.
- Dynamic and fast bass response that is well-integrated with the midrange.
- Reveals incredible detail in well-recorded source material.
Cons
- The revealing nature can highlight flaws in poor-quality recordings or low-bitrate streams.
- They demand a quality amplifier and source components to perform at their best.
- Not the ideal choice for those who prefer a very warm or laid-back sound signature.
I would recommend the MartinLogan Motion 40i to music lovers and home theater enthusiasts who have a dedicated listening space and are willing to invest in supporting equipment. You should buy these if your priority is analytical clarity, wide imaging, and a lively presentation. However, you should consider other options if your room is very bright and reflective, or if your primary sources are low-quality streams and you prefer a more forgiving, relaxed sound.
