This listing is for an ATC C1 Mk2 active subwoofer in black ash with original packaging. I purchased this new in October 2022 from Terry at GC HiFi (original receipt available).It makes the perfect partner to the ATC SCM11 standmount speakers and ATC SIA2-100 integrated amplifier I also have list...
This A$2,050 asking price is a strong bargain, sitting well below the 25th percentile of A$2,147 from your 32 recent AUD comparables and far under the median of A$3,483. With the original UK retail around A$3,200 (converted from £1,650) and current US new-stock listings near A$5,300, this listing offers genuine upside for a Mk2 generation unit that still competes with modern subs.
The ATC C1SUB Mk2 is a well-regarded, high-current powered sub prized for its tight, musical low-end and seamless integration with ATC mains. Its active design and robust build make it a timeless choice for hi-fi and home cinema, and buying at this price means you’re getting a premium sub at a fraction of its typical used value—especially if it’s in original-owner condition with cables and documentation included.
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.
