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 electrostatic panel is translucent, allowing the speakers to 'virtually disappear' in a room despite their size
- The electrostatic panel provides excellent midrange coherence and evenness with no coloration, creating a non-fatiguing sound that is open and pure
- The speakers reproduce a large and detailed soundscape
- Bass performance is improved in comparison to previous generations due to advancements in the bass section
- The speakers do not excessively color the sound, conveying it in its purity and effortlessness
Product Considerations
- Placement can be tricky, with the bass cabinets inseparably tied to the electrostatic panels
- The speakers' impedance drops to .7 ohms at 20 kHz, requiring a powerful and stable amplifier
- Room placement is more critical compared to traditional speakers due to dipole radiation patterns
- The bottom end can be perceived as 'pushy rather than inviting'
- The speakers automatically go into standby mode when not in use, which can cause a slight delay when music initially starts playing
Comparisons (according to reviewers)
- The MartinLogan ESL 13As are more relaxing than the Raidho D-3.1, which is designed for 'audiophile maniacs'
- The Expression reproduces a larger soundscape than the Bowers & Wilkins 800 D2 towers
Takeaway: The MartinLogan Expression ESL 13A is a high-performing speaker that provides transparent and detailed sound. With careful setup, the speaker's improved bass technology and electrostatic panel will bring many hours of listening enjoyment.

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.

- Vs KEF LS50 Wireless II: The LS60 offers improved performance and near full-range playback, but at a higher price, the LS50 Wireless II offers similar clarity with a slightly warmer sound
- Vs Klipsch Forte 4: The LS60 is more suited for home theater use and surface more detail

Our take on the brand
Our Summary
Product Strengths
- Transparent presentation, effortless dynamics, pinpoint imaging, and bass extension
- Sounds more neutral, more open and slightly better focused, especially in the lower octaves
- Detail is defined, and the dynamic performance is highly nuanced and sensitive
- Dirac Live compatibility allows for highly customizable and smooth sound
- Plays with an authority normally associated with speakers twice their size
Product Considerations
- The status LED on the front does not replace a display
- Setup is not exactly intuitive
- Without Dirac Live, the bass can sometimes be too strong for music listening
- A dedicated midrange unit would give both strings and woodwinds more depth and body
- Dirac adjustment slightly reduces volume levels, as some frequencies are attenuated
Comparisons (according to reviewers)
- Vs KEF LS60 Wireless: The bass response is tighter and better defined
- Vs KEF LS60 Wireless: The soundstage is more open and transparent
- Vs KEF LS60 Wireless: The stereo perspective is more sharply defined, and the soundstage is larger
- Vs ELAC Navis ARF-51 & NAD C 658: A deeper soundstage is created, with better front-to-back layering and image specificity
- Vs ELAC Navis ARF-51 & NAD C 658: During intense passages, the presentation was more transparent
- Vs KEF LS60 Wireless: Piano sounds better because nuances are more clearly defined and the treble reproduction is airier
Takeaway: The Dynaudio Focus 30 is a great system because it sounds very detailed with pinpoint imaging. The Focus 30 is perfectly suited as a wireless speaker for those seeking excellent sound in their home.
Video review
Our take on the brand
Our Summary
Product Strengths
- Anthem Room Correction (ARC) Genesis allows use to calibrate the speakers to specific room acoustics up to 300 Hz
- Hybrid design features built-in amplifiers powering the bass section, delivering up to 1000 watts for the three woofers per speaker, which allows accurate and controlled reproduction of powerful bass
- Delivers detailed, dynamic, and musically engaging sound with deep, controlled bass and clean and sparkling highs
- High premium finish and the cabinet is soft to the touch
- The design is elegant, with a tapered cabinet and an angled crease running diagonally across the side panel
Product Considerations
- At more down-to-earth levels it became pretty evident that the 120H are well overendowed in the bass department
- The design issue of the Paradigms active X-over network somewhat 'screws' up the sound at SPL below 75dB
Comparisons (according to reviewers)
- Founder 120H has a larger cabinet and Carbon-X bass drivers than the Paradigm Founder 100F
- The Founder 120H has an overall fuller and more rounded sound than the Revel F228Be, but Revels have a slightly more refined-sounding treble response
- The Founder 120H delivers high-end audio performance at more attainable prices than the Paradigm Persona 9H
- The Founder 120H has that same deep dynamic capacity where they do not fluster easily—if at all—when pushed
Takeaway: The Paradigm Founder 120H offers high-performance sound and technology, like room correction, at a more accessible price. The active bass section, quality design, and build make this a compelling listening experience for any music genre.

Our take on the brand
Our Summary
Product Strengths
- The aluminum cabinet is cast in one piece, which offers acoustic advantages and looks chic
- The extruded aluminum yields a seamless, curved cabinet, which minimizes standing waves, reduces diffraction, and distributes and controls reflections
- Highs are provided by a ribbon tweeter designed by PIEGA, and made by hand at the company's factory
- It creates an incredibly wide soundstage, always balanced and rich
- They are big enough to make big sound, but small enough to be suitable for a small apartment
Product Considerations
- The fit and finish of the small, square, lightweight Connect is basic—in sharp contrast with the stylish, substantial 701 loudspeakers
- DSP automatically adjusts each speaker's frequency balance according to volume, at a low setting, bass and treble are subtly boosted while, with something closer to party levels, the bass is gently reined in to prevent driver overload
- The Android version won't 'read the room' and only lets one turn the room correction on and off
Comparisons (according to reviewers)
- Vs KEF R3 Meta: it gives a cleaner sounding mid-range and better top-end extension
- Vs Buchardt A700: pairing the speakers to its black box comes with fewer connection hassles
- Vs KEF LS60 wireless: it draws a wider soundstage, better image in the mids, and offers a more extended top end
Takeaway: The PIEGA Premium recMsY5ljWopDD7UU is a stylish speaker that offers a wide soundstage and a rich listening experience. Its modern design and high-quality build make it a great addition to any contemporary living space.
