BLAM is a French car audio company founded in 2013 by industry veteran Guy Bonneville. The name stands for Bonneville Laboratory And More, reflecting the brand’s focus on research, engineering, and sound development. Bonneville created BLAM after decades of experience designing speakers and audio products, with the goal of building equipment that delivered his personal vision of musical, emotionally engaging sound inside a vehicle.

​

The company manufactures a full range of car audio products, including component and coaxial speakers, tweeters, woofers, subwoofers, amplifiers, and complete vehicle-specific audio systems. Their lineup ranges from entry-level upgrade speakers to high-end audiophile series, with some of their flagship products designed and assembled in France.

​

BLAM is known for what they describe as a “French Sound” tuning philosophy. This typically emphasizes natural vocals, detailed midrange response, and smooth highs rather than overly aggressive or harsh output. Because of this, the brand has built a reputation more in sound-quality (SQ) builds than high-output SPL systems.

In the car audio industry, BLAM is considered a boutique, specialty-shop brand. While not as widely known in the U.S. as some mass-market brands, they’re respected among enthusiasts and professional installers for their musicality, build quality, and audiophile-leaning design approach.
