Elegant Form Meets Studio-Grade Innovation | Available at Trimira Audio
The Bowers & Wilkins 804 D4 Floorstanding Speaker brings advanced 800 Series Diamond technology into a more traditional floorstanding design. Finished in luxurious Satin Rosenut with an aluminium top plate and light grey Connolly leather detailing, the 804 D4 combines refined aesthetics with sophisticated acoustic engineering.
Featuring B&W’s Solid Body Diamond dome tweeter, Continuum™ FST™ midrange driver, Biomimetic Suspension, and dual Aerofoil™ bass units, the 804 D4 delivers detailed imaging, natural vocal reproduction, and controlled low-frequency performance in a versatile footprint.
The reverse-wrap cabinet design improves structural rigidity and acoustic dispersion, while the aluminium plinth with downward-firing Flowport™ provides a stable foundation and efficient bass tuning.
