Bowers & Wilkins 804 D4 Floorstanding Speaker Pair

The Bowers & Wilkins 804 D4 encapsulates the essence of the 800 Series Diamond in a slim, elegant cabinet  engineered to perform with breathtaking precision and musicality. It’s the ideal choice for audiophiles who seek world-class sound without the size of larger floorstanders.

At its heart is the Diamond Dome tweeter, delivering crystal-clear highs, mounted in the Solid Body Tweeter-on-Top housing to reduce resonance and enhance detail. The Continuum™ cone FST™ midrange ensures lifelike vocals and midrange transparency, while the Biomimetic Suspension minimizes coloration for a pure, open sound.

Twin Aerofoil™ cone bass units produce rich, dynamic low frequencies, supported by Matrix™ internal bracing for exceptional rigidity and clarity. The Flowport™ design enhances airflow, ensuring smooth, distortion-free bass response.

Beautifully finished in Gloss Black, White, Satin Rosenut, or Satin Walnut, the 804 D4 blends acoustic excellence with timeless design — a perfect harmony of performance and elegance.
