Offered is „COLTRANE QUINTET EXTREME“ by Marten Design as new device from the category „Standing Speaker“ on audio-markt.de - the online market place for high-end. The advert with the number 524534811 ends on 09.12.2026 at 08:36 o'clock.
The Coltrane Quintet is a current, ultra-high-end design whose new pricing starts around €170,000, with higher-finish and Statement versions costing more. At €225,000, this listing is above the standard model’s new price and therefore looks ambitious unless it is a particularly rare finish, Statement-spec example, or includes exceptional dealer support; it is not an obvious used-market bargain.
The appeal is substantial: diamond and beryllium drivers, a carbon-fibre mid-bass, twin 10-inch aluminium-sandwich woofers, and a claimed 18 Hz–60 kHz response in a very rigid four-way cabinet. It should deliver scale, effortless dynamics, and unusually deep, controlled bass without a subwoofer. Before paying this premium, verify the exact specification, finish, age, warranty, packaging, and whether the €225,000 price is for the pair; pristine original-owner condition and full accessories would be essential.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Marten, a prestigious Swedish loudspeaker manufacturer, traces its roots to 1998 when Leif Mårten Olofsson founded the company, originally named Mårten Design. A trained electronics engineer with a lifelong passion for speaker design—sparked in his teens building prototypes in the family garage—Olofsson's breakthrough came from discovering Accuton’s ceramic diaphragm drivers in the mid-1990s. Now a family-run enterprise led by three Olofsson brothers—Leif as chief designer, Jörgen as CEO, and Lars as art director—the brand shortened its name to Marten in 2007 to reflect its evolving sophistication.
Exclusively focused on high-performance loudspeakers, Marten specializes in floorstanding models renowned for their fidelity and visceral sound reproduction. Iconic lines like the Mingus (the debut two-way design), Coltrane Supreme (introduced in 2006 as their most powerful system), and later evolutions such as the Coltrane Supreme 2 (2014) and Supreme Extreme flagship employ cutting-edge materials including pure ceramic and diamond cones, beryllium drivers, and innovative tweeters like the CELL. Hand-built with meticulous research, these speakers prioritize recreating recordings with uncolored accuracy, vanishing into the music rather than dominating the room.
Positioned firmly in the high-end audiophile market, Marten commands a niche boutique reputation for ultimate sonic perfection, distributed in around 30 countries and celebrated by discerning listeners worldwide. Models like the 2018 Mingus 20 anniversary edition underscore their heritage of technical innovation and emotional impact, appealing to buyers seeking reference-level transparency and dynamism in home audio systems.
