The 4th generation Motion Series ushers in a new era of design and aesthetics for MartinLogan. The three modern, yet timeless, colorways can compliment any room while being a focal point if so desired. Motion evokes a unique look and sound, pairing high-performance woofers with exclusive Folded Motion Tweeter technology, a staple of MartinLogan products. The Motion Waveguide enhances the Controlled Dispersion of the Gen2 Folded Motion Tweeter to a generous 90°(Vertical) by 90°(Horizontal) to accommodate a wide range of seating and speaker placement options, while avoiding clarity destroying sound reflections within the environment.

  • The MartinLogan Sound: Regardless of the environment, MartinLogan speakers achieve high levels of articulation, detail, and realism. Utilizing exotic thin film technologies and Controlled Dispersion, MartinLogan provides unique and special listening experiences not commonly found in the industry.
  • Gen2 Folded Motion Tweeters: The state-of-the-art thin-film Gen2 FMT offers effortless performance, unmatched by conventional technologies. Utilizing a lightweight material with more surface area, the FMT brings the audience’s favorite content to life with extreme levels of detail and accuracy.
  • Motion Waveguide: Enhances the Controlled Dispersion of the Gen2 Folded Motion Tweeter, blanketing the listening area with incredible detail and precision. Avoids performance robbing room reflections and provides a more consistent sound across a wider seating area.
  • Controlled Dispersion: Room acoustics are vital, as everything in the listening room has an impact on speaker performance. MartinLogan minimizes these harmful effects by focusing the sound into the listening area, increasing flexibility, clarity, and placement options, regardless of the room’s design.
  • Woven Fiberglass Midrange: The lightweight and strong Woven Fiberglass midrange in the Motion series is perfectly suited for keeping pace with Motion’s Gen2 FMT, providing crystal clear dialogue and vocals, as well as lifelike instrumentals.
  • McCracken-Vojtko Crossovers: The culmination of combining extensive anechoic, in-room measurements, and multiple blind listening tests with the low distortion philosophy of MartinLogan’s signature Vojtko Crossover. Through this process each speaker was refined to achieve peak performance.
  • Enchanced Cabinet Bracing: If a speaker cabinet isn’t braced properly, it will vibrate or resonate, resulting in masked clarity and detail. This 4th generation Motion series features specially engineered bracing to maximize sound quality by minimizing unwanted vibrations and resonances.
  • Secure Lock Grilles: Stealth mounting tabs securely hold the grilles in place allowing the listener to customize the appearance of each speaker. Creating a unique look; leaving the grilles on, off, or even rotating them to change the grain of the fabric providing maximum aesthetic control.
  • Single Cannon Bass Ports: Rear ported speaker designs need ‘room to breathe,’ which can conflict with a room's layout or decor as they require ample spacing from a wall or cabinet. The bottom mount port provides deeper, cleaner, and more powerful bass across a wider range of placement options.
  • Floor-Bounce Compensation: Bringing studio reference sound to reality with precision woofer placement and crossover tuning, MartinLogan engineers have designed their tower models to produce a more natural and full sound by taking advantage of a constant found in all listening rooms; the floor!
  • F.A.S.T. Foot: Toolless height adjustability utilizing rubber feet or spikes allows the user to perfectly level the speaker for maximum stability on any floor. Built-in anti-vibration properties lower distortion by reducing ‘judders’ between the speaker and the floor, leaving nothing but pure sound.

    A Great Speaker but consider the XT B100 aswell

    These speakers are great as standalone speakers. Their bass digs decently deep with great resolve on the tweeter. The soundstage is good with very good separation of instruments and vocals. Present a great a center image. I will say if you have good subs already at your disposal, opt for the XT B100 bookshelves from Martin Logan’s. Doing a direct AB between these two, it was very apparent how the motion XT tweeter shines over the motion tweeter in these. The B100s have a very transparent sound, much better depth and a greater sense of scale surprisingly. They completely disappear and the sounds seems like it’s coming from a large canvas. A true marvel at their price. Just remember, they do not have solid bass and should be used with a sub, preferably crossing over at 80-100hz depending on your room and subs. Used a denon x4800h bi-amped for both speakers. If you have the space, B100 with good subs 100%!

    ML’s F20s create an urge to surge the volume.

    Martin Logan F20 speakers. I can’t claim to love my movie entertainment any more than I love my vast selection of music. Having the best reproduction of sound has been an ongoing pursuit. I want to have seat shaking sound when tanks rumble by or when rockets launch skyward on the screen and still be able to have accurate representation of individual instruments in a full orchestra or the overtones that separate the sound of a violin from a cello. With so much music and movies accessible at exceptionally high quality via streaming and disks, it’s now possible to recreate a theater or concert venue at home. I’ve been on a quest most of my life to do that very thing. PREVIEW: Yes, these Martin Logan speakers demonstrated an ability to deliver accurate reproduction of every sound. Honestly, I’ve found several competing speakers that are similarly accurate. What separates these Martin Logans from the pack is their ability to cover a range of quiet, even delicate tones or voices and deliver explosive sounds with equal ease. Although I anticipated Martin Logan’s famous capabilities in the upper frequency ranges, I was surprised at their competence handling bass with authority, and especially their very dynamic presentation. It was as if they had two personalities. They are subtle, beautifully delicate with detail layered on top of a rock’n roll’n raucous bad boy slam. The front stage they create is broad and it holds up well even seated off to one side of a room. They make voices easy to understand. My only internal debate concerns what room will they end up in: theater or my large family space? SETUP: From the heavy packaging to the accessory box with the gorgeous outrigger speaker supports, Martin Logan lets you know they think these speakers are special. Sliding the flawless black gloss speakers our of their fabric sock seals the deal. These are special speakers challenging the rest of the $3-5,000 competition. My largest room listening/viewing area is equipped with a Yamaha Aventage RXA860 acting as a pre-amp for a Parasound 5125 multi-channel amp, providing an honest 125w/channel into 8 Ohms, and 185w/channel into 4 Ohms, which is the load these Martin Logans most often present to an amp. Later on during my early listening tests I moved them to my smaller (14’ square) theater room where I use a Yamaha Aventage RXA2070. This less demanding space allows the 140w/ch available power to easily drive the F20s. These are demanding speakers which will over-stress AVRs that don’t have robust power supplies or aren’t stable with 4ohm speakers. [Such AVRs will have stickers advising you of problems with 4 ohm speakers.] With these two amplifiers, the Motion F20s will play loud, louder than the previous speakers that occupied these locations. Phono purists might be disappointed that I rely on Apple Music (up to 24-bit/192kHz) music streaming exclusively but that also means I can listen to Dolby Atmos-powered Spatial Audio. Movie sources include the highest quality audio streaming but more often I use the UHD or Blu-ray disk formats because I really do prefer best available audio/video quality. [Because I knew I would be listening to multi-channel music and movies, I added Martin Logan’s Motion 50XTi center channel speaker from their previous line-up. That deserves its own review, but, I can say it is equally impressive.]] LISTENING to MUSIC: I started with popular music from my youth, because it is so familiar to me. The Doors, “Spanish Caravan”, John Lennon’s voice on “Girl”, and the harmonies of Crosby, Stills, Nash & Young all have strong bass and drum accompaniment and very natural, recognizable male voices. Music was fun to listen to, but before I used room equalization on both of my AVRs, there were times when the upper bass stepped forward more than I remember. It didn’t keep me from increasing the volume on Van Morrison’s “In the Afternoon”. Here Morrison’s voice sounded like he was sitting on a stool in a club, very intimately sharing a memory. I also sampled selections from Stravinsky’s “Rite of Spring” because it features the orchestra’s a wide variety of instruments which all get are properly presented with the Motion F20s detailed and lightning fast transient response. I came forward in time and played a mix. Starting With Paramore’s “Big Man, Little Dignity:, Hayley Williams’s voice stays smooth and intimate. Miley Cyrus sounded raucous with her new recordings, especially the live recordings. Alicia Keyes “Butterflyz” and Alison Krauss “When you Say Nothing At All” were delivered with delicacy and proper attention to the variety of instruments and musicians on hand. Of course I had to invite song birds Arian Grande, Adele, Mariah and even Sam Smith to the audition. All of them easily filled the room with music that never fell short of realistic in quality, accuracy and volume. These speakers have no bad habits. Billie Eilish’s thundering bass accompaniment never sounded more present. LISTENING TO MOVIE SOUND-TRACKS: I have this internal debate about what I want in my speakers. I’ve typically put my money on speakers that are completely neutral, with a ruler flat frequency response. This too often has meant I must sacrifice dynamics, the widest range of the loudest to the quietest sounds. My very accurate speakers often sound strained when forced to cover a broad volume range. If dialog is fine, the explosive scenes must be limited. These Martin Logan F20s toss out that limitation. These F20s challenge you to play your most dynamic movie sound tracks and enjoy the entire range of sounds. Almost every Jurassic Park movie, Star Trek movies, the Mummy series, Star Wars all want to be played on a sound system that can soar to the extremes while staying loud but no harsh in any way. I sampled scenes from each of these and these movies haven’t sounded better. The newest Top Gun sequel could convince the neighborhood to run to their windows for a flyby. It demands to be be played at realistic volumes, and the F20s don’t disappoint. I also remembered to play my favorite streaming soundtrack, “The Politician”, and the wonderful “River” by Joni Mitchell sung by Ben Platt. I have never heard it sound better, more real, more “right there in the room” like the entire episode (and series) which was recorded wonderfully. QUIBBLES? You definitely want to use your AVR’s or pre-amp’s auto-equalization. Those systems in my two Yamaha’s nicely corrected what I interpreted as an over-active bass response that starts in the lowest frequency range and has the potential of muddying male voices. Well, I’m probably the only person trying to dial back the bass region of these wonderful speakers. Some owners will see this as an opportunity to delay buying subwoofers. Another fault, which you likely will NOT see as a problem, is these speakers really love to be played at volume. I find they come into best tonal balance at louder volumes in larger spaces. Don’t get me wrong, I usually listen at normal even softer volumes, but the Martin Logan’s create an urge to surge the volumes. SUMMARY: These Martin Logan’s fill my large family room better than any speakers I’ve ever owned, and with less sense of strain. I strongly urge that new owners match these with an AVR or Amp that has an equalizer, better yet, AUTO-equalizer feature to get the best performance. Many end users will want to ensure the bass equalization brings the Martin Logans into a balance for YOUR unique room size and layout. After doing this for my room, that upper bass sounded authoritative but balanced. The lower bass is outstanding. The treble always sounded natural, and I preferred a towed-in orientation of my speakers. Many buyers will wonder if they should have spent extra for the bigger Martin Logan Motion Series. I can’t imagine needing larger unless you have a massive living space. Highly Recommended.
