Overview
The KEF LS60 Wireless speaker system was evaluated for its design, technical specifications, and auditory performance. The assessment focused on the speaker's aesthetic integration, its ability to reproduce different music styles, and the overall user interaction with its features.
Approach
The evaluation involved a personal assessment of the KEF LS60 Wireless speakers, focusing on their visual presentation, internal components, and sound fidelity when playing various musical selections. Specific attention was paid to how the speakers handled different sonic characteristics, such as bass, midrange, and treble, across diverse genres including funk, jazz, classical, and pop. The practical aspects of integration into a living space and the functionality of its accompanying app were also considered.
Findings
- Design and Aesthetics: The KEF LS60 Wireless speakers feature a slender, column-like design, measuring approximately 110cm tall, 20cm wide, and 30cm deep. They exhibit a minimalist aesthetic with a black finish and subtly rounded edges. The speakers include a Uni-Q driver array, a feature commonly found in KEF's high-end models, which integrates the tweeter within the acoustic center of the midrange cone. Airflow is managed through lateral ports at the bottom of the column.
- Acoustic Performance:
- Bass Response: The speakers delivered a "tight" and "punchy" bass, demonstrating accuracy without excessive rumble, even when playing tracks with prominent basslines. The bass was described as having a "warm glow" rather than being "overwhelming."
- Midrange and Treble Clarity: Vocals were reproduced with "exceptional clarity," allowing for distinct articulation of lyrics. High-frequency sounds, such as cymbals, were rendered with precision and a "shimmering effect," avoiding harshness.
- Soundstage and Imaging: The speakers created a wide soundstage, making it seem as though sound emanated from beyond the physical speaker boundaries. Instruments were distinctly separated, providing "impressive layering" and allowing individual elements within complex mixes to be discerned.
- Genre Versatility: The KEF LS60 Wireless performed effectively across a range of genres, including funk, jazz, classical, and pop. In a specific instance, a classical piece by Smetana was reproduced with individual string sections clearly audible, while a funk track by Lettuce maintained energetic bass and clear horn sections.
- Technical Specifications and Connectivity: The system is defined as "Wireless HiFi speakers" and supports playback at resolutions up to 24-bit/384 kHz. It offers various inputs including HDMI ARC, optical, coaxial, and RCA connections, alongside wireless streaming capabilities via Wi-Fi, Bluetooth, Spotify Connect, AirPlay 2, and Google Chromecast. The system supports multiroom audio.
- User Experience: The accompanying KEF Connect app was found to be user-friendly, providing settings for bass output and balancing the soundstage. Physical controls on one of the speakers allow for volume adjustment and source selection. Despite the substantial power (1400 Watts across both units), the speakers are designed to be energy-efficient.
Why This Matters
The KEF LS60 Wireless speaker system offers an integration of sophisticated design with high-fidelity audio reproduction. Its versatility across different music genres, combined with comprehensive connectivity options, addresses a demand for premium audio solutions in diverse listening environments. The system's ability to create a broad and detailed soundstage, alongside its user-friendly interface, contributes to an enhanced auditory experience.
The product's design, which emphasizes a compact footprint despite advanced acoustic engineering, may appeal to users seeking high-performance audio without compromising on spatial aesthetics.
