ATC SCM100ASLT LE Floorstanding Loudspeakers I've found something I'd like to try next, so I'm a bit more motivated to consider offers this time around. As the second owner we have enjoyed them for a few years, but it's time for someone else to be delighted and enjoy them! The previous owner sold them to me with a few marks however they're barely noticeable, never bothered me, and you can easily polish out and touch up. Please come and inspect and see pics. So cosmetically not perfect but they work like a dream and have all the ATC magic you can imagine. If you email ATC like I did, they w
ATC’s SCM100ASLT LE is a rare, high-end 3-way active floorstander that delivers massive bass, coherent midrange, and ATC’s legendary soft-dome tweeter with fully analog tri-amp power. The A$22,000 asking price sits well below the typical used market—where similar SCM100ASLT pairs often list between A$30,000 and A$40,000 AUD—and is also significantly under the A$50,000 AUD MSRP, making this a strong bargain for a well-regarded model.
This listing is worthwhile because the LE variant is a limited edition with original-owner backing, original receipt available, and likely includes factory grills and stand spikes. The speakers’ 350W Class AB tri-amp design, 115dB max SPL, and 32Hz–25kHz response make them ideal for large rooms and dynamic music. At this price, with no condition or warranty issues noted, it’s a genuine buying opportunity for enthusiasts seeking top-tier active performance without paying new-retail costs.

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.
