ATC SCM11 Bookshelf Loudspeakers For sale are my SCM11s which are in beautiful condition. I would be surprised if the prospective buyer would be disappointed in their second hand condition. These are very nice detailed speakers, currently paired with a Roksan Blak which powers them perfectly. I recommend something with similar power characteristics for these as they aren’t very sensitive. Only selling due to my desire to try their bigger brothers, the SCM19s. Still have original double boxed packaging. Cheers, Luke Condition: Excellent Payment Method: EFT or Cash on Pickup Region/State: (

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.
