Locating all of the moving elements around a single axis makes for an exceedingly cohesive and unified wavefront but in this case, we use the full Soul Six integrated-flux driver with main driver and ring-radiating supertweeter fully conjoined. Union Six Supreme is astonishingly vivid, yet nuanced and subtle when it needs to be.
It delivers salacious slam and scale in real-world spaces without forcing you to organize your room around the speakers. Discover intricacies you've missed in your music until Union Six Supreme, and you're likely to hear new energy in dynamic swells, too.
U6 Supreme features our new more sophisticated ZuGriewe and scatter plate internals that eliminate the fussy floor gap and instead allow the main driver to "see" the room via a rear exit. You can place Union as close as 2" [51cm] from the wall behind it. It is both highly efficient and generally amp-friendly, with its 8 ohms impedance.
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:
- They employ a full-range driver design, often paired with a super-tweeter, to achieve a coherent and crossover-free sound across much of the frequency spectrum.
- Zu speakers are known for their high efficiency, making them compatible with a wide range of amplifiers, including low-powered tube amps.

What if you spend more?
Soul Six is natural, unhyped, uncolored, and confident as [cuss]. Zu’s redesigned Soul 6 loudspeaker combines the build quality to rival the finest furniture with a sound that sets a new standard for what is possible within a modern form in an accommodating size. It’s what happens when design and engineering fall helplessly in love with the sonic promise and architecture of the classic Zu Soul. How good is it? Possibly the best mid-format floor standing loudspeaker yet. The Souls will amaze your ears, eyes, and your brain—and are built to do it decade after decade without losing one bit of their magic. Price is for a matched pair. Select black or silver aluminum tweeter lens and driver trim ring during checkout (no up charge).
Our summary
Product Strengths
- High detail retrieval with excellent soundstage and imaging, allowing performers to seemingly float in the room
- Design-conscious aesthetic with furniture-quality attention to detail and finish, appealing to audiophiles and non-audiophiles alike
- Gripping, lifelike dynamics and sincere tone, filling the space like a real instrument
- Relatively easy to drive due to its 8-ohm impedance and 100 dB sensitivity, making it compatible with various amplifiers
- Lighter in weight at 39 pounds, making setup easier and less sensitive to room placement compared to other speakers
Product Considerations
- Bass response may be a little shy in some rooms, lacking overall impact and depth depending on room size
- Upper midrange can sometimes have a bit of 'bite' or become slightly brash on certain recordings
- Proper adjustment of the Zu-Griewe system (gap setting) is crucial for optimal bass and lower midrange performance
- Upgrading the spikes is recommended to provide more options to adjust the gap between the bottom of the speakers and the floor, for better bass articulation
- Detail-oriented nature may reveal flaws in poorly recorded music
Comparisons (according to reviewers)
- Vs Volti Audio Razz: Both have equal amounts of detail and effortlessness, but the Razz has better bass impact

Takeaway: The Zu Soul 6 is an aesthetically pleasing speaker that sounds great and will integrate well into most rooms. It provides a lifelike and emotional musical experience, and it functions with almost any amplifier.

Our take on the brand
Bring the track spirit into your home with LS60 Wireless Lotus Edition, created in partnership with and inspired by the British Racing Green of the iconic brand.
Product Strengths
- Striking, sleek, and modern design that complements modern interiors
- Incorporates KEF's Uni-Q driver array and Metamaterial Absorption Technology (MAT) for neutral, open, detailed sound, reducing unwanted sound from the rear of the tweeter
- Includes Uni-Core force-canceling woofers that reduce cabinet vibrations, contributing to balanced and detailed bass
- The KEF Connect app allows for adjustments to fit the listening environment
- Offers high connectivity and is a true stand-alone system
Product Considerations
- Bass can be a bit too much out of the box, requiring adjustments via the app or placement considerations
- Not well-suited for those who have many signal sources to connect to
- Some reviewers found the bass lacked definition in the upper bass, with unclear instrument placement, even after adjusting EQ settings
- The included remote control is considered basic or cheap
- Mandatory online registration and administrator-level internet connection requirements for the app may be a drawback for privacy-conscious users
Comparisons (according to reviewers)
- Compared to the Bang & Olufsen Beolab 28, the LS60 Wireless can achieve similar sound quality with adjustments, at a lower price point, although the Beolab 28 sounds 'more right' straight out of the factory
- Compared to the KEF LS50 Wireless II, the LS60 Wireless is preferred stylistically, achieves near full-range playback, and has a more slim design, although it costs more and also provides much deeper bass
- Compared to the Q Acoustics Active 400 Towers, the LS60 Wireless has no issues with products not working
Takeaway: The KEF LS60 Wireless are stylish, all-in-one speakers that deliver a balanced, detailed sound with advanced technology. They are a convenient, high-performing solution for those seeking a streamlined audio setup.

Our take on the brand
Product Strengths
- Superb design and build quality.
- Articulate sound, especially in the upper midrange and treble regions.
- Very good imaging, with strong definition and delineation between instruments and performers.
- Vivid and clear midrange, revealing subtle details in recordings.
- Transparency ensures more of the music is heard as it was intended.
Product Considerations
- A capable amplifier is needed due to impedance dips to 3.1 ohms.
- Not a bass-heavy speaker.
- The tweeter can become too much if listening to poorly recorded music or at very high volumes.
- The bass can sound a bit thin, depending on room size and personal preference.
- Can sound a little bit cool when playing certain types of music.
Comparisons (according to reviewers)
- Vs KEF R11 Meta—KEFs presented more physical scale with respect to soundstage, with even greater width.
- Vs Polk R700 and Klipsch RP8000F Mk2—Not better than the B&Ws, but aren't embarrassed by them either.
- Vs B&W 805 D IV—In one listening room, the 703 is nearly as good.
- Zoo sound a little bit warmer.
Takeaway: The 703 S3 makes listening engaging and fun, with dynamic sound suitable for both music and movies. It brings clarity to vocals, especially at lower volumes, making it great for late-night listening.

Our take on the brand
Product Strengths
- Trickle-down technology from the 800 series narrows the gap with higher-end models
- Improved clarity of details, accuracy, and soundstage width compared to previous 702 models
- Clean and articulate bass is often attributed to the downward-firing port and plinth arrangement
- Excellent imaging and soundfield, with impressive width and height
- Delivers high definition and low coloration, offering a taste of the 800 Series experience
Product Considerations
- Careful positioning is required to achieve optimal tonal balance and musicality
- A reasonably powerful amplifier (minimum 75W recommended) is needed to perform at its best
- May not be a great match for valve amplifiers, preferring solid-state options
- The satin black MDF plinths are integral and require additional floor space
- Difficult to move around due to their weight (over 40 kg each) and lack of handholds
Comparisons (according to reviewers)
- Compared to the 702 S2 and 702 Signature, the S3 has improved clarity, accuracy, and soundstage width
- Compared to the Focal Aria 936 K2, the reviewer prefers the aesthetics of the 702 S3
Takeaway: The 702 S3 is a well-built loudspeaker offering a significant upgrade in sound quality. Trickle-down technology gives a taste of Bowers & Wilkins' flagship series at a more affordable price.

Our take on the brand
What competes at this price?
Our Summary
Product Strengths
- Exceptional speaker at pretty much any price
- Retains everything the reviewer loves about their Soul VI speakers in a more affordable package
- Provides 80% of the performance of the Soul VI in nearly every criteria
- Transparent, and showed off a lot of what the system was capable of doing
Product Considerations
- Made from MDF, which is heavier than the Okoume used in the Soul VI
- A bit less refined than the Soul VI
- Tonal presentation is very similar to the Soul VI, with the Union 6 being a bit less refined
- Without a direct comparison to the Soul VI, the reviewer would not have noticed that it felt slightly slower and less explosive
- If using in a 2-channel home theater setup, a subwoofer might be desired for the last octave of bass
Takeaway: The Union 6 is a great sounding speaker that can scale into high-end systems. It could easily be someone's first and last speaker.

- High levels of detail come through with the High-Velocity Folded Ribbon AMT tweeter and cast-basket mid/bass units

- The Santa Barbara Red finish option receives high marks for its visual appeal
Product Considerations
- Still a significant investment, especially the Santa Barbara Red finish
- The metal grille covering the drivers is not designed to be easily removed
- Care should be taken with system matching, due to a slightly hot high-end
Comparisons (according to reviewers)
- The T66 offers more refinement and a more 'of-a-piece' sound than the Triton One.R
- Has internal structural improvements that make it even more stable and rigid than previous generations

- Elegant design with a combination of wood and leather that gives a classy appearance
- Impressive bass output, with some reviewers noting deep and tuneful bass
- The midrange is articulate and expressive, delivering vocals with palpability and detail
- Smooth and detailed high-end reproduction, thanks to the Damped Apex Dome (DAD) tweeter

Product Considerations
- Requires careful placement to achieve the best balance, especially regarding toe-in

- Some reviewers mention the included binding posts are cheap
Comparisons (according to reviewers)
- Compared to the Q Acoustics Concept 50, the Lumina V has a more live sound, but the Concept 50 is more neutral, and more inert
- Compared to the Polk R700, the Lumina V is sonically similar to the R700, but with slightly less bass and a smaller cabinet—with better aesthetics; the R700 is more full range and warmer
- Compared to the Spendor A4 or ProAc Response DT8, the Lumina V is not as precise, but offers a natural sonic grace
Takeaway: The Sonus Faber Lumina V is an elegant speaker that delivers detailed sound and impressive bass. It is a great option if you want speakers that look as good as they sound.
Video review
Our take on the brand
Our Summary
Product Strengths
- Remarkably coherent and balanced sound profile, resulting from well-engineered and matched drivers and cabinet
- An uncanny ability to 'disappear' in the listening room
- The DPC array design contributes to a wide horizontal dispersion, allowing a broader sweet spot for multiple listeners
- Accurate sound reproduction and neutral enough for studio use
- A high level of dynamic ability, good low-end control, and a cavernous soundstage
Product Considerations
- Only available in gloss black and gloss white finishes, which might not suit all tastes or home décor
- The price point is a significant investment, placing it beyond the reach of many
- Some reviewers noted a mild treble roll-off, or smooth character that was overly kind on poor recordings and might lack the sparkle and excitement some listeners prefer
- Setting up requires assistance, due to the weight
- The lower bass extension may not satisfy deep bass enthusiasts, with extension starting to drop below 40Hz
Comparisons (according to reviewers)
- Compared to the Perlisten S7t, the S7t offers more overall weight, bottom-end reach, resolution, and dynamic speed, but the R7t shines brightly on its own
- Compared to the EgglestonWorks Oso, the Oso presented a more muscular version of the music with more bottom end oomph, while the R7t conveyed music's finer points with more apparent resolution
- Compared to the KEF Reference 3, the KEF may yield deeper bass extension due to greater cabinet volume, and the scale of the soundstage may also be improved, but the Perlisten offers a superior disappearing act
Takeaway: The Perlisten R7t are well-built speakers that provide a detailed and immersive listening experience, with their advanced design and unique driver array creating a spacious soundstage. Their cutting-edge design creates a great listening experience.

Our take on the brand
Our Summary
Product Strengths
- Excellent midrange imaging and naturalness, described as smooth and stunning
- Smooth treble with a timbre and natural decay that allows for hours of listening without fatigue
- Expansive soundstaging with good imaging, height, and depth
- Stellar overall balance makes it an outstanding performer
- Beautiful wood veneer with high polish lacquer and attention to detail in construction
Product Considerations
- Bass will not reach subterranean levels, a subwoofer may be required for strong bass enthusiasts
- Speakers may benefit from more power
- "Messy music" (genres with rawness or grime) may not be conveyed as well, as the speaker can be a little polite
- Excellent clarity was brilliantly showcased by Ray Gelato's Basin Street Blues, beautifully recorded on the Linn label, which may not appeal to all audiences
Comparisons (according to reviewers)
- Compared to the standard Antal Ez, the 40th Anniversary edition uses a lighter—more rigid anodized-magnesium tweeter for higher efficiency, lower distortion, and better directivity
Takeaway: The Triangle Antal 40th Anniversary is a well-balanced and beautiful loudspeaker with a stunning midrange that provides a musical and engaging listening experience. Its clarity, expansive soundstage, and beautiful design make it a great addition to any audiophile's setup
