Quad has introduced the ESL 2812X and ESL 2912X, the sixth generation in its lauded series of full-range electrostatic loudspeakers. Representing the culmination of more than 65 years of electrostatic innovation, these new models succeed the ESL 2812 and 2912, being retired after a thirteen-year production run, bringing improved electronics, better transformers, and an updated finish.
These are not radical redesigns, says the brand. Instead, they stand as methodical improvements to an already mature concept, honouring the legacy of founder Peter Walker, who introduced the world’s first full-range electrostatic speaker in 1957.

What’s New in Generation X
The ESL 2812X and 2912X retain the same dimensions and architecture as their predessors – four electrostatic panels in the 2812X, and six in the larger 2912X. The changes are mostly under the hood. Key upgrades include refined electrostatic panel production techniques, a complete redesign of the electronics, and newly developed UK-built audio transformers, all aimed at increasing sonic performance and long-term reliability.
The new models also debut a matte-black ‘stealth’ finish – replacing the traditional wood trim – for a more modern, unobtrusive look. A discreet LED Halo lighting effect can be switched off or dimmed, providing a visual counterpoint to the speakers’ tonal subtlety without calling undue attention to itself.
How electrostatics work, and why they matter
Most loudspeakers use moving coil drivers: cones or domes that are pushed and pulled by magnets. Electrostatics, by contrast, operate using a charged diaphragm; an ultra-thin sheet of Mylar suspended between two stators. The diaphragm moves in response to an electrical field created by the musical signal.
The result is a driver that is lighter, faster, and more responsive than any conventional cone. There’s very little inertia and almost no mechanical colouration. The benefit is a degree of openness and realism that remains hard to match. Particularly in the midrange, the part of the frequency spectrum most attuned to the human ear, they are known for startling clarity and low distortion.
The ESL 2812X and 2912X are full-range electrostatic designs, with no moving-coil bass drivers. This is relatively rare in the industry. While hybrid speaker designs can deliver a wider dynamic range, or more visceral low-end thump, they’re seen as a compromise by Quad.
By contrast, these ESLs aim to produce a seamless sound field, where instruments and voices appear to hang in space without the boundaries which could be imposed by traditional enclosures. For those seeking the truth in a string quartet, a vocal performance, or a live jazz recording, they demand an audition.
Technical innovations
The ESL X series introduces several meaningful technical refinements. Still based on Peter Walker’s original design, but with modernised manufacturing. Each diaphragm is now more precisely tensioned and more consistently coated, improving transparency and uniformity across panels.
They also introduce innovative Tri-Module electronics. Where earlier models used a single PCB, the X series splits operations across three dedicated boards, for high-voltage multiplication, signal handling, and protection. This significantly reduces noise and interference between circuits.
They also boast new audio transformers. Designed and built in the UK under the supervision of Quad’s service team, these provide wider bandwidth and higher linearity. Transient detail is said to be crisper, and the sense of depth more pronounced.
For those who already appreciate the sound of a Quad ESL, this may be the upgrade you’ve been waiting for.
For those new to electrostatics, the Generation X models offer a rare opportunity to hear music in its most unadorned form, delivered by a technology that, decades later, still plays by different rules.
The Quad ESL 2812X and ESL 2912X will be available from August 2025. They’re priced at £10,999 per pair for the 2812X, and £12,999 per pair for the larger 2912X.
Danish audio outfit DALI has announced a new Hi-Fi speaker series, which combines advanced acoustic engineering with contemporary Scandi design. Landing globally in February 2026, the Sonik range will comprise seven models covering stereo, home cinema and on-wall applications. The enclosures come a choice of finishes: Black Ash, Walnut, Natural Oak and White, complete with…
The Audio-Technica Hotaru is a music system like no other. This limited-edition turntable combines analogue vinyl playback with magnetic levitation and reactive lighting. Only 1,000 units have been made, each priced at €9,999. The design is intended as both a high-end music system and a sculptural object d’art. The Hotaru uses a floating structure and…
Now here’s something you don’t see every day: a £35,000 sound system built from a real Lamborghini supercar exhaust. The iXOOST ESAVOX isn’t a concept or a marketing gimmick. It’s a fully functional Bluetooth sound system handcrafted in Italy from genuine Lamborghini components, complete with a working start/stop button that powers on the system, much…
