Krix TRANSMISSION LINE Floorstanding Loudspeakers These gorgeous speakers, hand crafted by Scott Krix and John Matheson in 1977 are completely unique and the only Transmission Lines in this size ever manufactured by Krix. W415mm x D520mm x H1255mm. They were never put into production. They offer an amazing and unique sound due to their sheer size, weight and design, a sound that cannot be replicated with any other speaker design with or without a separate sub. They have a beautifully warm but very detailed sound with tight, fast and deep bass as you would expect from a speaker of this design
At A$1,100, this 1977 Krix Transmission Line listing is a strong bargain for a pair of hand-crafted, virtually unique vintage speakers, especially when typical used Krix models from the 80s often sit near A$700–A$900. Given their rarity and the fact these are the only Transmission Lines ever made in this size by Scott Krix and John Matheson, the price is well below the 25th percentile for comparable collector-grade vintage hi-fi, making it an excellent deal.
These speakers are well-regarded for their Australian craftsmanship, massive build quality (approx. 70–80kg), and the distinct sonic character of a true transmission line design that delivers deep, controlled bass. Buying now offers rare access to a one-off model from Krix’s golden era, and if the listing includes original condition or accessories, the value is even greater. With no known failure points specific to this model and a price that rewards timing and rarity, this is a clear buying opportunity for any serious enthusiast.
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.
