KEF LS Luxe Wireless Speakers: High-End Audio With Strict Placement Needs

KEF has moved decisively upmarket with the LS Luxe, a wireless stereo speaker system that aims to combine cutting-edge engineering with a bold aesthetic. Priced at £3,499 / $3,999 / AU$6,399, it sits alongside the Sonus faber Duetto as a premium option for discerning listeners.

According to TechRadar's review, the LS Luxe delivers a deftly accomplished performance, blending forensic detail retrieval with an energetic, forceful character. The tonal balance is described as exquisitely neutral, and the system handles dynamics, rhythm, and vocal expression with confidence. The speakers retrieve and contextualize fine details effectively, making for an engaging and communicative listen.

On the specification front, the LS Luxe is well equipped. It features a 12th-generation Uni-Q driver array with a 25mm aluminium tweeter and a 165mm mid/bass driver, plus KEF’s metamaterial absorption technology. Amplification is hybrid: 280W Class D per mid/bass driver and 100W Class A/B per tweeter, totaling 760W. Connectivity includes Wi-Fi, Bluetooth 5.3, HDMI eARC, optical and coaxial digital inputs, a 3.5mm analogue input, and a pre-out for a subwoofer. It supports high-resolution playback up to 24bit/384kHz via network inputs.

However, the review highlights a significant caveat: the LS Luxe is very fussy about positioning. The speakers require minimal toe-in and careful placement to achieve optimal soundstage width and height. Even when positioned correctly, the soundstage is not the largest you’ll hear, though it is well-controlled and well-laid-out.

Design is another differentiator. Built in collaboration with Ross Lovegrove, the cabinets use a moulded compound with no seams, resulting in an organic, almost sculptural appearance. Three finishes are available: eclipse black, mineral white, and dusk titanium. The review notes that the black finish makes the speakers look bulkier than they are.

One point of contention is the optional S-Luxe stands, which cost £799 / $799 / AU$1,199. They are almost mandatory for optimal aesthetics, but third-party stands work fine, even if they don’t match the speakers’ swooping shape.

Considering daily use, the LS Luxe offers plenty of input options and stable control via the KEF Connect app, though it can be sluggish. The system is not fully wireless—both speakers need mains power, and a physical connection between them is required for the highest resolution.

Who should consider upgrading? Those seeking a high-end wireless system with exceptional sound quality and a unique design, provided they are willing to invest time in positioning and budget for the expensive stands. It’s not for those who want a set-and-forget solution or who expect a massive soundstage.

TechRadar’s verdict: pound-for-pound, it’s one of the best wireless stereo speaker systems you can buy, but perfection is elusive due to placement sensitivity and the cost of optional accessories.
