Offered is „SCM 20 SL“ by ATC as second-hand device from the category „Standing Speaker“ on audio-markt.de - the online market place for high-end. The advert with the number 6599143355 ends on 01.11.2026 at 06:18 o'clock.
ATC’s compact monitors are a serious piece of engineering, and this one is priced in the upper-fair zone rather than bargain territory. At €5,000, it sits above the €4,364 median and below the €8,074 75th percentile, so it’s a respectable ask for the market, but not a steal.
That still makes sense if the speaker is genuinely clean, original, and fully functioning, because ATC’s midrange clarity, low distortion, and studio-grade neutrality are the whole appeal. The upside here is mostly in condition and provenance: if it’s been well cared for, with original drivers and no history of hard use, this is the kind of buy that can be kept long term without feeling like you overpaid.
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.
