HARMAN International has announced that it has become a NASCAR technology partner aimed at delivering premium audio experiences for racing fans through future racetrack audio upgrades.
This partnership enables NASCAR to design and implement integrated audio systems using HARMAN Professional Solutions brands, including JBL Professional loudspeakers, Crown amplifiers, BSS digital signal processing, and more.

Founded in 1948, NASCAR is the premier sanctioning body of stock car racing in North America. The most iconic of its 14 racetrack properties include Daytona International Speedway, Talladega Superspeedway, Michigan International Speedway and Phoenix Raceway.
Through this technology partnership, HARMAN’s product offerings will be used to improve sound quality for race fans across the racetrack properties whenever it becomes necessary.
In addition to the primary exterior racetrack areas, NASCAR venues feature numerous interior spaces where intelligibility and high-quality audio is essential for announcements, broadcast coverage, and music.
Brian Divine, president of HARMAN Professional Solutions, said: “JBL and NASCAR are two iconic brands that were founded just two years apart in the 1940s, and will now work together to enhance one of the most thrilling and widely attended sports in the worldOn any given day, thousands of fans around the world experience audio through a JBL system, and we are excited to collaborate with NASCAR through this technology partnership to bring them even closer to the action through superior sound.”
John Martin, vice president, chief technology officer at NASCAR, added: “With millions of fans attending NASCAR events in person each year – and millions more watching on TV – our races demand the highest levels of performance and reliability from all technical systems. Not all suppliers can meet NASCAR’s rigorous standards, but HARMAN’s brands have a proven legacy of innovation, exceptional sound reproduction, and day-in, day-out reliability, making their products an ideal fit for our venues.”
Further details on the partnership and specific audio integrations will be announced as the 2025 season progresses.
