What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
Product Strengths
- The Folded Motion tweeter aims to replicate some qualities of electrostatic speaker panels and produces a distinctly natural, organic, and smooth presentation of sound
- Handsome and comes in a choice of gloss black or white or a walnut wood veneer, its slender dimensions allow these mini-towers to blend nicely in even the most formal of rooms
- The cabinet features reinforced internal bracing, with 1.2-inch thick MDF baffles and 0.7-inch thick MDF walls, which help to reduce cabinet resonances that might otherwise color the sound
- Broad imaging characteristic provides a wide soundstage, which translates into a large listening sweet spot
- Build quality is excellent, with flawless cabinet quality, and fine details such as a front trim plate that covers the driver mounting hardware
Product Considerations
- Getting the Motion 20i to create a believable stereo image is not quite as simple as it might seem, careful toe-in is required
- There is a mild deficit in image depth, and bass extension isn't particularly competitive, low bass falls short of what many may expect from a floorstanding loudspeaker
- Placement requires care and can sound too laid back
- The Motion 20i doesn't always possess the type of clarity and definition in the midrange to create an accurate stereo image
Comparisons (according to reviewers)
- Vs GoldenEar Technology's Triton Seven: Pricing is in line, making them directly comparable, and the Triton Seven has a deeper bass response down to 29Hz, while the Motion 20i has the luxurious finish
- Vs Emotiva's Airmotiv T1+: The Airmotiv T1+ is a tremendous value, however, the appearance of the T1+ is not as refined as the Motion 20i
- Vs Spendor's A2: The Spendor can't quite match the space and three dimensionality of the Motion 20i and is less sensitive, but the A2 is far less demanding about where it is placed in a room and delivers a far superior level of rhythmic engagement
- Vs Focal Kanta No. 2: The Motion 20i could come as close as it did to the Focal Kantas presenting more bass and midrange, as well as overall image size, due to the substantially larger overall speaker cabinet size, and with the upper-frequency range, it was a dead heat
- Vs Monitor Audio Gold GX50: The 20is had a slightly narrower sweet spot, and, compared to the GX50's, the 20is don't always possess the type of clarity and definition in the midrange to create an accurate stereo image
- Vs MartinLogan Electro Motion ESL: The Electro Motion ESL has a disparate design, if someone was shopping around for a MartinLogan speaker in this price range, they would be tempted to bump up their budget and clear a little extra floorspace
Takeaway: The MartinLogan Motion 20i is a well-built and handsome speaker with a Folded Motion tweeter that delivers a smooth and natural sound, making it a great choice for long listening sessions. If a user is willing to spend a little time making sure it is working correctly in their room, this is a supremely talented and highly appealing small floorstander.

Brand highlights
Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:
- MartinLogan's defining CLS (Curvilinear Line Source) electrostatic panel technology provides exceptionally wide horizontal high-frequency dispersion, exceeding that of traditional flat panels and offering a more immersive soundstage.
- The brand uniquely integrates powered dynamic woofers with its electrostatic panels, employing custom DSP engines and advanced crossover designs to achieve seamless blending and extended, well-defined bass response.
- MartinLogan's commitment to full-range sound reproduction, even in smaller models, results in a "large" sound that defies the speaker's physical size, projecting height and scale often unmatched by comparably sized speakers.
- They provide Anthem Room Correction (ARC) as an option, allowing users to tailor the bass response to their specific listening environment and achieve optimal integration between the speakers and the room's acoustics.

Our summary
Product Strengths
- Impressive aesthetics and stylish design enhances room appearance
- Amazing sound, with notable clarity, balance, and overall neutrality
- Wide and precise imaging and expansive soundstage creates a 3D sound effect
- Excellent bass extension and dynamic capabilities
- Good value for the price
Product Considerations
- May be a difficult load for lower-end receivers, potentially requiring a more robust amplifier
- Larger size might not be suitable for smaller rooms
- Treble stands out a little bit, and recordings that favor the treble can start to sound harsh as the volume increases
- Heavy—each speaker weighs 76 pounds
- There isn't a grill that can be removed, however, they do come with soft fabric bags that you can put over the speakers when they are not in use
Comparisons (according to reviewers)
- Martin Logan bests the Polk R700 with respect to attack and decay and detail and texture rendering
- Martin Logan showcased even less audible and measurable resonances than the Wharfedale Elysian 4
- Martin Logan excels in bass reproduction, but overall, the reviewer finds the KEF R5 Meta's sound profile more neutral
- Prefers the more focused and natural sound of the Martin Logan XT F100 over Definitive Technology Dymension DM70 and DM80
- Advocates for this speaker over Martin Logan's biggest bookshelf with a sub—it advocates very well for itself for why one should go this route versus, say, subwoofer satellites, unless one is just really tight on space
Takeaway: The Martin Logan Motion XT F100 tower speakers are fantastic speakers that deliver high-end reference grade sound. You'll enjoy a premium listening experience with a best-of-all-worlds value that delivers at basically every audiophile speaker level.

Our take on the brand
Our summary
Product Strengths
- High sensitivity (92dB/W/m) allows them to work well with modest amplifiers
- Massive bass from two big aluminum drivers
- Downward-venting bass port makes the speakers easier to position
- Big, bold, room-filling sound with excellent detail and solid stereo image
Product Considerations
- Highs can be a little bit bright or forward depending on the music
- Soundstage depth may not be amazing and could require more break-in time
- The walnut finish with a matte black baffle may not appeal to everyone, giving it a 'macho' look
- Factory rates the speaker at 4 ohms, meaning it can dip below that
Comparisons (according to reviewers)
- The F10 is considered the 'baby brother' to the Martin Logan XT f100, with the f10 having a slightly recessed vocal
Takeaway: The Martin Logan Motion F10 speakers provide a remarkable listening experience with a powerful, detailed sound that works well with a variety of amplifiers, and are easy to set up with flexible placement. They offer excellent build quality, and their high sensitivity allows them to deliver impressive sound even at low listening levels.

Our take on the brand
Our summary
Product Strengths
- A brand new folded motion tweeter within a wave guide provides a nice wide dispersion, not only horizontally, but vertically as well
- Very detailed speakers with a crisp, clean quality to the top end, and a wider soundstage that came across wider horizontally throughout the entire room
- The F20 tower speakers' bass response digs impressively low, and the attack has a clean punchy tactile heft to them
- The C10 center channel has some growl to it, with Palpatine's chesty voice coming directly at the listener
Product Considerations
- The MP10s have a pretty hard cutoff, so they aren't producing much bass at all, and should be paired with a subwoofer
- The F20s sounded brighter than the reference speakers, and the louder that the volume turned up, the harder it got on the listener's ears
- The bass extension of the F20s is not as deep as the reference speakers
Takeaway: The Martin Logan Motion series provide detailed sounds with crisp quality to the top end, making movies and music come to life. They are a great choice for those looking for high-quality sound.
Video review
Our take on the brand
Our summary
Product Strengths
- Fit and finish plus performance that is a bargain for around $3k/pair
- Gelcore cabinet construction minimizes unwanted sound energy from resonance and vibrations
- A tweeter that is hermetically sealed and mechanically isolated (floating) from the baffle provides lower distortion
- Size, weight, and richness of tone belies their size, with a wider baffle to each loudspeaker pointing at you
- A mild sound throws emphasis back to the midrange that in itself seems almost holographic, as well as deeply insightful in a gentle but revealing manner
Product Considerations
- A medium to large size room is required to shine, otherwise the bass will dominate
- Flaws in poor recordings can be revealed due to their detail and accuracy—warts and all performance
- The top-end is a little soft and gentle—classic BBC like—which may require amps with some zing to compensate
- Listeners seeking absolute detail or transparency might not be satisfied because of Q Acoustics' house sound that massages treble and plumps up bass and lower mid
- They don't go sub-40Hz deep, frequency response is rated at 42 Hz – 30 kHz (-6dB)
Takeaway: The Q Acoustics Concept 50 offers excellent value with its blend of innovative design and high-quality sound, making it a great choice for enjoying music with a sense of depth and engagement. The Concept 50s are easy to listen to and fun.

Our take on the brand
What competes at this price?
Our Summary
Product Strengths
- The AMT tweeter brings openness to the sound
- Next-level feet/outriggers provide superior decoupling and prevent tip-overs
- At 92 dB sensitivity, it is very easy to drive with a variety of amplifiers
Product Considerations
- Rear ports require mindful placement to avoid sounding boomy or bass-heavy if placed too close to the back wall
- Finishes can be damaged during unboxing or with wear and tear
Comparisons (according to reviewers)
- Vs SVS' Prime Pinnacle Speakers: The biggest sonic difference will be the sound of the AMT tweeter versus the more traditional dome tweeter
- Vs Bowers & Wilkins 603 S3 speakers: Expect a little less bass from the Bowers & Wilkins 603 S3 speakers, which have one less bass driver
- Vs GoldenEar Triton Seven speakers: The GoldenEar product delivers an AMT tweeter, possibly the closest analogy on the high-frequency performance
Takeaway: The MartinLogan Motion Foundation F2 speakers are audiophile-grade speakers that deliver ample bass, punchy midrange and the benefits of an open high frequency. They are easy to drive, well-crafted, and come in appealing finishes.

Video review
Our take on the brand
Our Summary
Product Strengths
- Flat in-room frequency response, especially from 200 Hz upwards, contributes to accurate sound reproduction
- Amplifier and receiver friendly due to its high sensitivity and 8-ohm impedance, performing well with entry-level to flagship AV receivers and amplifiers
- The new, larger Tractrix horn waveguide design offers improved directivity control and high-frequency focus
- Excels in dynamics, delivering raw impact and presence that enhances the excitement of movies and gaming, as well as rock and electronica music
Product Considerations
- Treble might become fatiguing with lesser recordings or at higher volumes, and may not be agreeable with all genres for listeners seeking a very smooth top end
- The midrange, while linear, isn't completely neutral due to some cabinet resonance, adding extra energy that may or may not be desirable depending on listener preference
- For true full-range playback, a subwoofer is required to compensate for the lack of deep bass extension
- The vinyl finish may disappoint fans of natural materials
- Best listened at within a 5-degree angle, and listening at a height level with the tweeter is clearly the best choice
Comparisons (according to reviewers)
- Vs. Polk R700: R700 is a more versatile all-rounder, but preferred for rock and electronica
- Vs. Sonus Faber Lumina 5: The Sonus Faber is better built and looks nicer, but more refined
- Vs. Q Acoustics Concept 50s: The Concept 50s image a little better, disappear just a little bit better, and they are exceptional off-axis, but do not play as low
- Vs. Heco Aurora 1000: The Heco is more linear across the range
- Vs. SVS Prime Pinnacle: The SVS Prime Pinnacle has a tweeter that is lower in level, offering a warmer sound
Takeaway: The Klipsch RP-8000F Mark II is a speaker that brings a dynamic sound to movies, gaming, and music. For speakers that are easy to set up, are amplifier-friendly and deliver punchy, clear audio, these could be a great option.
Video review
Our take on the brand
Our Summary
Product Strengths
- Creates a very open and transparent soundstage, which crosses the threshold of believability in a small to medium-sized room
- Low distortion, especially in the midrange and upper bass, making listeners realize how imperfectly transparent many speakers are
- Highly resolving, with impressive performance on acoustical instruments and vocal reproduction
- Offers a unique and remarkable experience due to the story and love behind the speaker's creation
- Presents a challenge, helping users understand speaker positions as the sound changes completely with movement
- Considered 'eminently affordable' and provides incredible sound for the price
Product Considerations
- Requires significant time to install, tweak, and dial in due to its dipole design, making positioning critical
- Bass is not powerful—it doesn't do pounding bass, and listeners won't feel the bass pounding on their chest, so a subwoofer might be needed, especially for rock, pop, dance, and electronic music
- Needs good power and high current to sound clean and not cause fatigue, it is not a powerful-sounding speaker
- The stand included is considered subpar and not very versatile
Comparisons (according to reviewers)
- Vs the original LRS, the LRS+ has ameliorated treble, has smoother upper mids, and has a reduced nosedive in the power range and midbass
Takeaway: The Magnepan LRS+ is a special speaker with an open soundstage, great details, and makes music sound real and enjoyable. Though not perfect, it is well worth buying because it offers an excellent way to experience a panel speaker without spending too much.
