Piano black in excellent condition as rarely used. 2 x 6inch long throw opposing drivers 35hz - 120hz 200 watt 237w x 308h x 241d mm Stereo phono and LFE inputs
The asking price looks like a strong deal for a Quad subwoofer in this market. At £250, it sits well below the £413 25th percentile and far under the £735 median of the recent comparable GBP listings, so this is priced to move rather than priced ambitiously.
Quad’s low-end pieces are usually bought by enthusiasts who want clean, musical bass rather than a thumpy home-theatre effect, and that makes a good-condition example worth grabbing if the rest of the system suits it. In excellent condition, the main upside is simply getting a well-regarded piece at a very forgiving entry price; I’d still confirm it’s complete and working quietly, but there’s no obvious price-based reason to hesitate.
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.
