At AXPONA 2026, Marten Global Sales Manager Martin Dunhoff talks about the company's $500k Marten Coltrane Quintet Extreme loudspeakers in an interview with Ken Micallef that's now posted on our YouTube channel.
Although time constraints prevented me from doing a proper listening evaluation of this million-dollar open-air Marten system at AXPONA 2026, Global Sales Manager Martin Dunhoff was able to tell me all about the company's new $500K Marten Coltrane Quintet Extreme loudspeakers.
Being a huge Trane fan, I heartily approve of the product name.
