Fantastic condition with original boxes and packaging. These are exceptional speakers for this price
ATC’s SCM40 is one of those serious floorstanders that always carries a proper studio-grade reputation, and at £3,200 this listing sits just above your £3,130 median and a touch above the £3,232 75th percentile. That makes it slightly ambitious, but not out of line if the cosmetics are genuinely excellent and the speakers are presentable enough to buy with confidence.
What makes it worth considering is the usual ATC strengths: exceptionally clean midrange, high-resolution detail, and a neutral, unforced presentation that works brilliantly with good amplification. In a clean, well-kept pair, condition matters a lot because these are heavy, premium speakers that buyers tend to keep for years; if the listing includes original packaging, spikes, or proof of careful ownership, that adds real value.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
ATC (Acoustic Transducer Company), a British engineering powerhouse, was founded in 1974 by innovative loudspeaker designer Billy Woodman. Initially focused on crafting custom drive units for the professional audio sector, the company quickly gained acclaim with its 12-inch PA75-314 driver, renowned for superior power handling and minimal distortion at high sound pressure levels. In 1976, ATC introduced the groundbreaking SM75-150 soft dome midrange driver, revolutionizing dispersion, bandwidth, and clarity in studio monitors.
The brand specializes in high-precision loudspeakers, designing and manufacturing its own drivers—including tweeters, midrange, and bass units—in-house for both professional and home applications. Its SCM series offers a spectrum from compact models like the SCM7 to larger formats, available in active and passive configurations. ATC also produces standalone electronics, such as preamplifiers, power amplifiers, and integrated amps like the SIA2-150, all built to uncompromising standards of accuracy and reliability.
ATC commands a elite position in the high-end hi-fi market, revered by recording studios worldwide for its transparent, detail-revealing monitors and by discerning audiophiles for domestic speakers that deliver reference-grade performance. A professional ethos, advanced materials, and innovations like the Super Linear Driver—slashing distortion in the vocal range—cement its status as a boutique leader, where precision engineering trumps mass production.
