Developed over an eight-year period and first featured on our flagship 800 Series Diamond models, the Continuum cone has been integrated into the sixth generation of the critically acclaimed 603 to transform the performance you expect from an entry-level speaker. The 603 features the proven Decoupled Double Dome tweeter, with a re-engineered assembly for better performance.
Our improved paper bass cones combine effortless power and endless low-end with the precision and low-distortion accuracy you’d expect from Bowers & Wilkins. But the new 603 speaker isn’t just about cleaner sound – it boasts a cleaner look, too. We removed grille pegs and replaced them with magnets, while moving the port to the rear cabinet, creating a modern and premium aesthetic, wrapped with a matte finish.
Fill your home with beautiful Bowers & Wilkins sound.
