Offered is „M&K Sound, Miller + Kreisel Subwoofer X12“ by MKSound as exhibit from the category „Subwoofer Active“ on audio-markt.de - the online market place for high-end. The advert with the number 9899707414 ends on 11.11.2026 at 06:09 o'clock.
With good condition, €1,999 is a bit firm but not out of line for an M&K X12; new pricing for this model was around €2,900–€3,000 equivalent, and the wider used market I’d expect to sit roughly around €1,700–€2,200 depending on age and cosmetics, so this is near the upper end of fair rather than a bargain. The condition note helps, but it does not quite make it a steal.
What you’re paying for is the classic M&K formula: sealed, fast, low-distortion bass with real home-theater authority and excellent integration for music and movies. The X12 is well regarded as an upper-tier sub that can still sound controlled rather than bloated, which is the main reason to buy one used. At this price, I’d want to confirm it’s fully original, the amp is quiet, and it includes the grille and any packing—otherwise there’s not much cushion if something is missing.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
M&K Sound emerged in 1973 when Walter Becker of Steely Dan commissioned recording engineer Ken Kreisel and audio retailer Jonas Miller to design a studio reference subwoofer and monitoring system for the Pretzel Logic album sessions. The company was formally founded in Beverly Hills, California, in 1974, establishing itself from the outset as a professional-grade audio manufacturer rooted in real-world studio and mastering applications.
The brand built its reputation primarily on subwoofers and loudspeakers, becoming known for pioneering the dual-drive subwoofer design. M&K Sound's product portfolio spans studio monitors, home theater systems, and high-performance speakers engineered for both music reproduction and film applications. The company's work with top recording studios and mastering engineers solidified its standing as a choice for professionals demanding accuracy and sonic precision.
M&K Sound occupies the high-end professional and prosumer segment of the audio market, positioned between consumer brands and ultra-premium boutique manufacturers. The company's heritage in studio and mastering environments, combined with its influence on home theater development, establishes it as a respected name among serious audiophiles and home theater enthusiasts who prioritize accuracy over mass-market appeal. Though the brand experienced periods of dormancy, it has maintained relevance through its foundational contributions to audio engineering and continued recognition among discerning listeners.
