For SaleFantastic ATC SCM ASL 50 speakers in Rosewood finish.Purchased secondhand 2 years ago from a reputable Retail hifi shop in Melbourne.Regrettable sale - only selling because I have recently upgraded to ATC 150s model for a larger room.Very good condition; beautiful sound. No issues ;
Compared with a typical used pair at A$3,447, this asking price of A$13,500 is well into ambitious territory; it sits far above the A$6,999 75th percentile, so you’d want a very strong reason to pay it. Against the current market shape, it looks like a premium-owner, premium-condition number rather than a bargain, and I’d only lean in if the provenance and cosmetics are exceptional.
That said, this is a serious ATC floorstander with the sort of neutral, high-resolution presentation that rewards careful amplification and room setup. For a buyer who knows what these can do, the upside is in getting a mature, well-regarded design with real long-term listening value — but at this price, I’d want to see original packaging, complete accessories, and clear evidence of careful ownership before calling it easy money.
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.
