Bowers and Wilkins 804 D4 Diamond Series. For those seeking a timeless aesthetic and the impeccable performance of an 800 Series Diamond speaker, the 804 D4 is the perfect fit. Its curved cabinet, crafted from one piece, boasts improved sound diffusion and minimized cabinet reflections. Additionally, it stands on an aluminum plinth, equipped with a steel constrained layer damper, for sturdy stability. 804 D4 is the leader in the entry-level towers of the 800 diamond range. Upgrade to 803 D4 for larger bass drivers (180mm, 7-in) and a Turbine Head enclosure for the 130mm (5-in) midrange cone, increasing sound spaciousness.
