AMC B1-30 Subwoofer (Active / Powered) For sale is a high quality AMC B1-30 10" powered subwoofer. The amplifier is a Class AB unit built to the same standards as AMC's hifi amps and was recapped a few years ago with Panasonic and Nichicon 105 degree capacitors for much longer lifespan and better performance than the originals. The amp sits within its own rear chamber, separate from the subwoofer enclosure to minimise the effects of vibration on the amp. The external heatsinking and ventilation of internal PCB means it can run all day long. Cosmetically the sub is in great condition as sh
This is a buyer’s market for older powered subs, and A$120 looks like a strong buy on this AMC. The nearby listed sale at A$140 and another at A$120 put it right around the low end of the current used range, so this is comfortably fair-to-bargain territory rather than a stretch.
What makes it appealing is the combination of a solid 10-inch driver, Class AB amplification, and the fact that the amp has already been recapped with quality parts. That lowers one of the big risks on an older sub and makes it more attractive than a random unserviced unit. It should be a worthwhile pick if you want a compact music-friendly sub, provided you can audition it and confirm the amp is quiet, powerful, and free of hum or dropout.

AMC stands for Advanced Merit Concept, a brand name generated by computer in 1970 that signals the company's philosophy of staying one step ahead. The brand emerged from Weltronics Corp., based in South Pasadena, with product development split between London and Los Angeles, while manufacturing occurs in Taiwan. AMC's founder and owner, Amcli Lin, established the company's reputation through groundbreaking amplifier topology innovations in the 1970s—specifically soft clipping, soft crossover, and soft power supply designs that delivered the dynamic range and low distortion previously associated only with tube amplifiers.
AMC's product portfolio centers on high-end amplifiers and hi-fi components, with a deliberate design philosophy emphasizing 25-year reliability and affordable pricing for audiophile-grade equipment. The brand is recognized for combining innovative circuitry with traditional craftsmanship, resulting in components that maintain classic, timeless aesthetics while incorporating continuously refined internal technology. Their iconic "green button" has become a symbol of this commitment to enduring design paired with technical advancement.
Positioned as a serious audiophile brand rather than mainstream consumer audio, AMC occupies a distinctive niche: high-end performance at accessible price points. The company maintains an exceptionally low failure rate and is known among enthusiasts for exceptional value relative to sound quality. Though not a household name outside dedicated audio circles, AMC has earned respect within the hi-fi community for delivering professional-grade components with meticulous engineering and reliability that exceed industry standards.
