{"product_id":"quad-esl-2912x-electrostatic-speakers","title":"Quad ESL 2912X Electrostatic Speakers","description":"\u003cp\u003eThe Quad ESL 2912X represents the most advanced refinement of QUAD’s legendary electrostatic loudspeaker design to date. Building on the acclaimed ESL 2912 platform, the 2912X introduces precision-engineered upgrades throughout its construction, electronics, and transformers—delivering enhanced clarity, greater dynamic expression, lower distortion, and a more immersive listening experience while preserving the unmistakable QUAD ESL sound.\u003c\/p\u003e\n\u003ch2 style=\"font-size: 16px; font-weight: bold;\"\u003ePrecision Engineering from the Ground Up\u003c\/h2\u003e\n\u003cp\u003eEvery aspect of the Quad ESL 2912X has been re-evaluated through a comprehensive internal engineering audit. Using advanced laser-precision metrology, QUAD engineers refined the electrostatic architecture with improvements to diaphragm spraying, stator etching, diaphragm tensioning, transformer integration, and final assembly. These changes result in tighter tolerances, improved consistency, and increased transparency across the frequency range.\u003c\/p\u003e\n\u003ch2 style=\"font-size: 16px; font-weight: bold;\"\u003eWhy the ESL 2912 Became the ESL 2912X\u003c\/h2\u003e\n\u003cp\u003eThe cumulative impact of these engineering upgrades justified a new model designation. Rather than a minor revision, the Quad ESL 2912X represents a meaningful performance leap, offering a purer, more dynamic, and more controlled presentation that firmly places it at the top of QUAD’s modern electrostatic loudspeaker range.\u003c\/p\u003e\n\u003ch2 style=\"font-size: 16px; font-weight: bold;\"\u003eQUAD Electrostatic Heritage\u003c\/h2\u003e\n\u003cp\u003eThe ESL 2912X continues a lineage that began in 1957 with Peter Walker’s original full-range electrostatic loudspeaker. From the ESL-63 through to the ESL 2912, each generation has advanced transparency, coherence, and musical realism. The ESL 2912X retains the hallmark open midrange, absence of cabinet coloration, and effortless presentation for which QUAD ESLs are renowned.\u003c\/p\u003e\n\u003ch2 style=\"font-size: 16px; font-weight: bold;\"\u003eUltra-Lightweight Mylar Diaphragm\u003c\/h2\u003e\n\u003cp\u003eAt the heart of the Quad ESL 2912X is an ultra-lightweight Mylar diaphragm. Its exceptionally low mass enables outstanding transient response, high accuracy, and vanishingly low distortion, allowing music to be reproduced with remarkable speed, detail, and realism.\u003c\/p\u003e\n\u003ch2 style=\"font-size: 16px; font-weight: bold;\"\u003eAdvanced Point-Source Electrostatic Design\u003c\/h2\u003e\n\u003cp\u003eThe Quad ESL 2912X employs QUAD’s concentric ring stator geometry and delay-line system, derived from the legendary ESL-63 point-source principle. Charged to over 5.2kV DC and driven uniformly across its surface, the diaphragm moves precisely in sync with the music, producing stable phase coherence, pinpoint imaging, and a deeply immersive three-dimensional soundstage.\u003c\/p\u003e\n\u003ch2 style=\"font-size: 16px; font-weight: bold;\"\u003eBritish-Built Audio Transformers\u003c\/h2\u003e\n\u003cp\u003eA major upgrade in the ESL 2912X is the reintroduction of UK-manufactured audio transformers, developed under the supervision of QUAD’s specialist service team. These bespoke transformers improve linearity, reduce flux modulation at high sound pressure levels, and extend high-frequency performance beyond 18kHz for cleaner transients and greater dynamic expression.\u003c\/p\u003e\n\u003ch2 style=\"font-size: 16px; font-weight: bold;\"\u003eRevised Electronic Architecture\u003c\/h2\u003e\n\u003cp\u003eInternally, the Quad ESL 2912X features a newly segmented electronic layout, separating high-voltage multiplication, control and protection, and low-voltage signal handling into individual modules. This design significantly reduces electromagnetic interference and crosstalk, lowering the noise floor and delivering greater stability, finesse, and realism across all listening levels.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eType: Multiple electrostatic drive membranes\u003c\/li\u003e\n\u003cli\u003ePoint Source Time Delay: Progressive concentric rings\u003c\/li\u003e\n\u003cli\u003eFrequency Response: 32Hz – 21kHz (-6dB), 28Hz – 23kHz (useable)\u003c\/li\u003e\n\u003cli\u003eDistortion: Above 1000Hz \u0026lt;0.15%, Above 100Hz \u0026lt;0.5%, Above 50Hz \u0026lt;1.0% (100dB @ 1m)\u003c\/li\u003e\n\u003cli\u003eSensitivity: 1.5 mbar per volt referred to 1m (86dB \/ 2.83V rms equivalent)\u003c\/li\u003e\n\u003cli\u003eNominal Impedance: 8 Ohms\u003c\/li\u003e\n\u003cli\u003eImpedance Variation: 4 – 20 Ohms\u003c\/li\u003e\n\u003cli\u003eMaximum Output: 2 N \/ m² at 2m on axis\u003c\/li\u003e\n\u003cli\u003ePanel Elements: 6\u003c\/li\u003e\n\u003cli\u003eFormat: Floor standing dipole with 3° fixed tilt\u003c\/li\u003e\n\u003cli\u003eChassis Structure: Heavy duty composite aluminium \/ steel\u003c\/li\u003e\n\u003cli\u003eMaximum Input: Continuous input voltage (rms) 10V, Programme Peak for undistorted output 40V, Permitted peak input 55V\u003c\/li\u003e\n\u003cli\u003eDirectivity Index: See polar diagrams\u003c\/li\u003e\n\u003cli\u003eDimensions (H x W x D): 1470 x 690 x 380 mm\u003c\/li\u003e\n\u003cli\u003eNet Weight: 44kg\u003c\/li\u003e\n\u003cli\u003ePower Consumption: 8W\u003c\/li\u003e\n\u003cli\u003eAC Input: 220 – 240V, 100 – 120V\u003c\/li\u003e\n\u003cli\u003ePower Fuse: 100mA anti-surge (200–240V), 200mA anti-surge (100–120V)\u003c\/li\u003e\n\u003cli\u003eModel: ESL 2912X\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Quad","offers":[{"title":"Default Title","offer_id":58775519887744,"sku":null,"price":12995.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1002\/6926\/1184\/files\/Screenshot2026-08-25at16.54.19.png?v=1787673347","url":"https:\/\/thespinningroomhifi.co.uk\/products\/quad-esl-2912x-electrostatic-speakers","provider":"The Spinning Room Hifi","version":"1.0","type":"link"}
