What reviewers think

Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.

What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

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:

  • KEF's designs prioritize a "Single Apparent Source" through coaxial driver technology, aiming for a coherent soundstage where frequencies appear to originate from a single point, enhancing realism and spatial accuracy.
  • The brand incorporates "Metamaterial Absorption Technology (MAT)" into its drivers, utilizing a maze-like structure to absorb unwanted sound waves from the rear of the driver, resulting in cleaner and more defined output.
  • They offer a wide range of streaming and connectivity options, with their powered loudspeakers responding to the proprietary KEF Connect app, which delivers multiple streaming services and facilitates setup and customization.
  • KEF frequently collaborates with renowned industrial designers to create visually striking products that seamlessly blend into modern living spaces, balancing aesthetic appeal with acoustic performance.

T Series

  • Positioning: The ultra-slim speaker line, designed to complement modern flat-screen TVs with a minimal footprint.
  • Description: While delivering a sleek aesthetic, the flat diaphragm driver maintains rigidity and minimizes resonance, providing clean and accurate sound. However, compared to other KEF lines like the Q or R Series, it may offer less depth in bass response due to its slim design.

Q Series

  • Positioning: The entry-level range offers versatile speakers suitable for both stereo and home theater setups.
  • Description: Features Metamaterial Absorption Technology (MAT) and the 12th generation Uni-Q driver array, delivering detailed and natural sound. While it provides excellent value, it lacks some of the advanced damping and driver technologies found in the higher-end R and Reference Series, which offer more refined sound reproduction.

R Series

  • Positioning: Bridges the gap between the entry-level Q Series and the high-end Reference Series, incorporating technologies from the latter to enhance performance.
  • Description: Equipped with Metamaterial Absorption Technology (MAT) and the 12th generation Uni-Q driver array, delivers precise and immersive sound. Unlike the Q Series, it includes Shadow Flare technology to reduce cabinet diffraction, resulting in clearer high frequencies.

The Reference

  • Positioning: As KEF's high-end line, sets the benchmark for audiophile-grade sound reproduction.
  • Description: Incorporating Metamaterial Absorption Technology (MAT) and a 12th generation Uni-Q driver array, offers exceptional clarity and detail. It also features advanced cabinet construction and flexible port technology for cleaner bass compared to the R Series. However, it doesn't achieve the Single Apparent Source configuration found in the Blade Series, which provides even more precise imaging.

Blade Series

  • Positioning: Represents KEF's innovative approach to speaker design, featuring the world's first Single Apparent Source loudspeakers.
  • Description: With Metamaterial Absorption Technology (MAT) and the 12th generation Uni-Q driver array, delivers coherent and precise sound. Its unique cabinet design minimizes resonances and diffraction, surpassing the traditional enclosures of The Reference Series.

MUON

  • Positioning: Stands as KEF's flagship speaker, combining cutting-edge acoustic engineering with avant-garde industrial design.
  • Description: Crafted from super-formed aluminum, the rigid structure minimizes vibrations, delivering ultra-wide bandwidth and immersive sound. While it shares the Uni-Q driver array with other KEF models, its exclusive design and limited production make it a collector's item.

Our take on the brand

KEF's signature Uni-Q technology places the tweeter in the center of the woofer to create a single point source for sound, while their Metamaterial Absorption Technology absorbs 99% of unwanted sound from the rear of the driver. Their Music Integrity Engine corrects timing errors in the speaker crossover, and their Shadow Flare technology reduces diffraction for improved detail and clarity in sound reproduction.

  • Innovative in design and heavy duty in build quality

Product Considerations

  • The price of the S7c and the system as a whole, may be intimidating for some
  • The review sample had a lustrous high-gloss black with chromed silver binding posts and terminal plate

Comparisons (according to reviewers)

  • The Perlisten S7t speakers seem to be able to bend the room to their will to an even higher degree than the Revel F328Be speakers that were reviewed earlier

Takeaway: The S7c is a top-tier center channel speaker that delivers exceptional clarity and seamless integration with other speakers, making it a great choice for a high-end home theater system. It's a high-performing product, making movies and music sound their best.

S5c
5995
/
Released
2022
With the success of the S7c, the request for the S5c center for slightly smaller rooms and screens became too numerous to ignore. A world class center similar to the S7c with nearly the same SPL, sensitivity, and low frequency output. The S5c is sealed for the best integration into any room, and the same exquisite DPC array, for THX certified Dominus surround, or Ultra LCR home theater applications.

Our Summary

Product Strengths

  • Compact center channel designed to match the S7Ts without taking up too much space
  • Properly designed to be a center channel, providing great off-axis performance
  • When integrated as part of a system with S7Ts, it provides a cohesive sound, sounding very similar to the mains

Product Considerations

  • Review mentions having to seal the bass drivers in the subwoofers and redo setup
  • Review mentions it sounds best with 'really good musical subwoofers', which may mean it sounds less good without subwoofers

Takeaway: The S5C is a well-engineered center channel option that can be paired with other speakers to create an immersive sound experience. It offers great off-axis performance and a cohesive sound.

Bowers & Wilkins
HTM81 D4
9500
/
Released
2021
The center-channel speaker is arguably the most important in home theater – and the HTM81 D4 has an enviable array of advanced technologies to reinforce that point, including Solid Body tweeter-on-top, a decoupled Continuum™ Cone midrange drive unit and twin 200mm (8-in) Aerofoil™ bass cones.

Expand Details

Our Summary

Product Strengths

  • Confident, solid, and real presentation
  • Beefy-solid sound with very good imaging and focus, and with much better layering front to back than anticipated
  • Tweeters have a near-perfect combination of articulation and musical purpose, and are absolutely never bright or in your face
  • Arguably, the strongest point is their solid and unwavering presentation regardless of volume level
  • Has a live-performance-like quality

Product Considerations

  • Overall resolution is good, but not spectacular, and perhaps less than one should reasonably expect at this price
  • Tonal balance, compared to Apogee speakers, is definitely on the dark side
  • Exact same toe in is needed, otherwise focus will tend to either side
  • Bass was initially thumb–but was resolved by placement

Comparisons (according to reviewers)

  • Compared to Apogee: DSP 5200's have a lower stage, also, tonal balance is darker
  • Compared to Kharma: Kharma's are more open-sounding–but can be ear-piercing, while the DSP 5200's are never aggressive or harsh

Takeaway: The DSP 5200 SE speakers deliver a confident and solid sound, that does not lack power, and performs well at all volume levels. They are great at filling the room with sound and creating a thrilling listening experience.
