QUAD ESL ELECTROSTATIC SPEAKERS 2905, UPGRADED TO 2912 SPEC, BREATHTAKING Absolutely breathtaking performance, stellar looks, the QUADS are a statement speaker. In a small room, they’re like a giant pair of headphones. Intimate, immensely engaging, totally captivating and incredibly detailed. In a large space the sound takes on cathedral filling proportions. Unparalleled floor to ceiling sound stage and about as close as you can get to the live performance. The QUADS are ... read more
At £3,495, this sits essentially at the market median versus the recent comparable GBP listings, so it reads as fair rather than cheap. It’s also just under the £3,537 75th percentile, which means it isn’t ambitious for the model, especially given the excellent condition tag.
That makes it a sensible buy if you want a well-kept pair without waiting for a bargain. These are highly regarded electrostatic speakers for their speed, transparency, and imaging, with a big, open presentation that still rewards serious listening years on. The main upside is condition: if the panels are healthy, the stator bias is stable, and there’s evidence of careful ownership, that matters more here than chasing a slightly lower asking price.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Quad, the venerable British hi-fi brand, traces its origins to 1936 in London, when engineer Peter J. Walker founded S.P. Fidelity Sound Systems, soon renamed the Acoustical Manufacturing Company. Relocating to Huntingdon in 1941 after wartime bombing, the firm shifted from public address gear to domestic audio amid post-war demand for superior sound reproduction. Walker's pioneering ethos—prioritizing "the closest approach to the original sound"—defined Quad from its early QA12 amplifiers, adopted by the BBC, to the iconic Quad I of 1953.
The brand excels in amplifiers and electrostatic loudspeakers, revolutionizing both categories. The Quad II power amplifier of 1953 introduced cathode coupling for vanishingly low distortion, while the 1956 ESL 57 delivered the world's first full-range electrostatic speaker, employing a massless film diaphragm for unparalleled transparency and transient speed. Quad advanced into solid-state with the 1967 303 and transistor designs featuring innovative "Triples" output stages, later expanding to integrated amps like the 99 series, moving-coil speakers, and modern electrostatic models such as the ESL 988 and 989.
Today, under the International Audio Group since 1997, Quad holds a prestigious position in the high-end market, revered by audiophiles for its unyielding pursuit of accuracy over trends. Its heritage components command vintage collector status, yet contemporary offerings maintain a niche boutique appeal among discerning buyers seeking refined, distortion-free reproduction that honors Walker's legacy.
