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
- Deep soundstage, comparable to high-performing bookshelf speakers
- Excellent transient response, making sounds very realistic
- Clear dialogue reproduction, especially with higher voices
- Controlled dispersion, which benefits the timbral matching of speakers and minimizes off-axis sound
- Includes everything needed for various mounting options (wall, stands, horizontal)
Product Considerations
- Lower-pitched voices may cause some cabinet resonance, correctable by tilting the speaker
- Sounds of papers in surround effects were confined to the locations of the direct-radiating SLMs
- A subwoofer is needed to enjoy bass-heavy tracks
Comparisons (according to reviewers)
- The Motion SLM has superior high-frequency reproduction and depth of image, while the Angstrom Suono produces decent bass response without a subwoofer
- The Dynamo 700w sounds much tighter and performs better, while the PSB plays a bit louder
Takeaway: The Motion SLM system, especially with the Folded Motion Tweeter, sounds great and looks beautiful, enhancing flat-panel TV setups. MartinLogan provides everything needed to set it up easily, making it a great system.

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.

Video review
Our take on the brand
Product Strengths
- Nice bass extension down to about 40, 45 Hertz in the room
- Very low distortion and good dynamic range
- Excellent resolution throughout the frequency range
- Hybrid tweeter widens the sweet spot and opens up the soundstage
- Well-constructed and well-engineered
Product Considerations
- The speaker sounds a little too laid back in the mid-range
- High frequency has a lot of sizzle or pop, the level of the tweeter stands out more above the mid-range
- Without some equalization or some sidewall absorption, it is a tough sell
- SMC material reduces third harmonic distortion, and some people may feel that it is too polite
- May need a cooler and livelier amplifier to get the best sound
Comparisons (according to reviewers)
- Neat Elite Classics are only just a little less capable at shifting air at low frequencies and are a little more balanced tonally, whereas the Dali's are a little recessed in the upper mid-range
Takeaway: The Dali Rubicon 6s are well-engineered speakers that offer excellent resolution throughout the frequency range. The hybrid tweeter widens the sweet spot and opens up the soundstage.

Our take on the brand
Product Strengths
- Great sound and is considered one of the greatest audio bargains
- Even tonal balance, very neutral, and offers a balance of detail and exceptional musicality
- Creates a credible soundstage and reveals detail in well-recorded material, with a wide stage extending beyond the speakers and conveying depth
- Can play loudly with minimal effort due to its 89dB sensitivity and 8-ohm impedance
- Superb imaging, especially with two-channel listening
Product Considerations
- High-end finishes increase the price significantly
- Some reviewers find the grills flimsy
- Some reviewers found the speaker install difficult
- The height of the tweeter was a bit low for one reviewer, causing the soundstage to feel low at times
- Some reviewers find Axiom speakers as a whole as unforgiving or too bright
Comparisons (according to reviewers)
- Compared to PSB Platinum M2 and Usher X-718, the Axiom M60 v2 could play much louder and go far lower in the bass
- Compared to Onix Rocket RS450s, there's a considerably increased size of the soundstage
Takeaway: The Axiom M60 v2 speakers are a great value for their excellent performance and ability to draw one into their music. With a seemingly boundless dynamic range, they bring music to life and can be a solid choice if space allows.

Our take on the brand
What competes at this price?
Our Summary
Product Strengths
- The speakers produce a lively and informative sound
- The system has excellent cohesion, showing no jarring shifts in tone
- The system offers excellent detail and tonality, especially with voices
- The subwoofer integrates well and packs a good punch for its size
- The build quality is excellent with a high-calibre paint finish
Product Considerations
- The soundstage can be relatively small, and the system can struggle to convey the scale of some explosions
- Dynamics could be better—the system can fall a little flat dynamically when it comes to building tension
- Low frequencies from the subwoofer can sound overly bloated if the volume dial is cranked up too high
- Dispersion from the Mikro speakers is not as wide as some would like
- The sound might be too polite and small-scale for some tastes, lacking heft and authority
Comparisons (according to reviewers)
- The Fazon Mikro lacks the out-and-out heft, authority and dynamics of similarly priced packages like the Quad L-ite Plus or the Monitor Audio Radius R90HT1
Takeaway:
The Dali Fazon Mikro 5.1 is a stylish speaker package that delivers a refined and detailed sound for both movies and music. It's an assured system that's easy to admire because of the build quality and the solid sound.

Our take on the brand
Our Summary
Product Strengths
- Open, easy-going tone
- Agile, seamlessly integrated bass
- Stunning design and build quality
Product Considerations
- Small, fiddly cable terminals
Comparisons (according to reviewers)
- The 7000i system delivers outstanding sound quality, even more impressive than the KEF E305, Quad L-ite Plus, and DALI Fazon Mikro

Our take on the brand
Our Summary
Product Strengths
- Sweet and detailed audio performance with clear instrumental separation and expansive dimensionality
- Warm and full-bodied bass and midrange
- Clear yet 'mellow' treble, creating a pleasing sound signature
- Accurate sound that doesn't do much to color the recording, so listeners get a balanced presentation of the source content
- Good level of dynamic range for reasonably sized bookshelf speakers, and they can get louder than expected for their size/price class
Product Considerations
- The laid-back sound may occasionally obscure some definition
- The speakers run on the cooler side of things, never becoming too indulgent in any aspect and instead providing a sound that is accurate and slightly pulled back, but never muted or lifeless
- Asymmetry of the phase coherence of their vertical lobe can be a slight problem for anyone listening under the tweeter axis
- Does not feel as substantial as some other speakers in their price class
Comparisons (according to reviewers)
- Vs Focal Vestia No. 1: Theva offers a lot of what makes the Vestia No. 1 great while saving money, but is not as immediately striking in detail or treble extension
- Vs Bowers & Wilkins 606 S3: Theva is more compact and easier to place, but doesn't look as premium
- Vs Polk Legend Series L100: Theva has a more laid-back sound profile, making it a better listen in most cases, while the L100 presents a more precise center image
Takeaway: The Theva No. 1 is a great speaker for enjoying detailed and smooth sound without harshness. It's a good option for different types of content, from music to movies, and is especially suited for smaller spaces.

- When used on top of floor standers, they do not sound as good as when wall-mounted
- Dolby Atmos content availability may be lacking
Takeaway: The Alteco C1 is a well-built speaker that adds a cinematic feel to a home theatre experience. It is a versatile speaker that can be used in different ways and is a good value for the price.
