RARE OPPORTUNITYTrade in pair of KRIX CYCLONIX 15 Passive Loudspeakers PLEASE NOTE - THE CYCLONIX 15s are either side of the MX20 in the PHOTO IMAGESINFO AND SPECS:The Krix Cyclonix 15 is a high-performance, passive, front-vented bass-reflex subwoofer featuring a large 15-inch driver with a 100mm...
The Cyclonix 15 sits in Krix’s serious passive-sub camp: big 15-inch driver, high-output home-theatre leaning design, and the sort of build that appeals to people who want scale and headroom rather than compact convenience. At A$3,990, this listing feels ambitious unless it includes an excellent matching amplifier or extras, because the Cyclonix 15 is the same model sold as a passive sub and a new source listing prices it as a specialist product rather than a runaway-value piece.
What makes it worthwhile is the payoff: deep, room-filling bass with proper slam, and Krix’s reputation for robust, Australian-built home-audio gear. In like-new condition, the upside is mainly that you avoid the usual used-market headaches on a large passive sub—cosmetic wear, driver fatigue, or missing grille/fitment bits—so it’s most attractive if the original packaging, grille, and provenance are all present. If the included amp is substantial, the ask becomes easier to justify; if it’s just the cabinet, I’d want to pay notably less.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Krix Loudspeakers was founded in 1974 by Scott Krix in Adelaide, Australia, following his degree in electronic engineering. Beginning in a garage with basic hand tools, the company evolved from crafting bespoke speakers for friends into a globally recognized manufacturer. By 1976, Scott opened The Acoustic Foundry, a hi-fi retail concept that pioneered the "Design Your Own Systems" approach, allowing customers to audition and customize speaker elements. The Home Grown series launched in 1978, establishing Krix's first commercial product line across multiple price points and sizes. Today, the company remains family-owned and operated, with Scott and his brothers Gary and Ashley still active in the business after five decades.
Krix specializes exclusively in loudspeakers across three primary categories: commercial cinema speakers, home cinema systems, and high-end domestic audio speakers. The brand gained prominence in the 1980s by pioneering infinite baffle wall technology and constant directivity horn designs for multiplex cinemas, a market segment they dominated for two decades. Their commercial cinema speakers now grace over 4,500 installations across 40 countries. In 2010, Krix formalized its home cinema range, and by 2018 became the exclusive Trinnov Audio Commercial Cinema distributor for multiple regions.
Krix occupies the premium to ultra-premium tier of the audio market, positioned as a high-end specialist rather than a mass-market manufacturer. The brand commands respect among both professional installers and discerning audiophiles willing to invest significantly in sound quality. Their reputation rests on decades of engineering innovation, proprietary horn technology, and unwavering commitment to Australian manufacturing. Krix appeals to buyers seeking cinema-grade acoustics for domestic environments and those pursuing uncompromising audio performance, making them a niche but prestigious choice within the global hi-fi landscape.
