Product Information
Based on over 25 years of experience in designing and creating high-end speakers, we designed our speakers to fully express the unique sound concept referred to as French Sound.
French Sound is a subtle and very specific balance, designed to accurately reproduce the midrange details of music while preserving all the emotions of the voice. It faithfully reproduces the dynamics of the original recording but maintains all the natural nuances and vocal clarity that bring music to life.
Blam's new Signature line expresses all of Guy's 25 years of experience in car audio and product design; it simply achieves all the ideals and targets he set for the French Sound.
The Signature series is made exclusively in France. Each component is designed in BLAM's French laboratory. The product is manually assembled, rigorously tested, and purposefully paired in our newly designed workshop in France.
