The loudspeaker that sets the standard other high-end designs will be judged by for years to come. Endowed with every new technology the 800 Series Diamond™ has to offer, the reference-quality 801 D4 is an instant icon.
Bowers & Wilkins 801 D4 – Walnut
The Bowers & Wilkins 801 D4 represents the pinnacle of loudspeaker engineering, combining groundbreaking acoustic technologies with exceptional craftsmanship. As the flagship of the 800 Series Diamond, the 801 D4 is designed to deliver extraordinary clarity, precision, and realism, bringing listeners closer to the original musical performance.
The 801 D4 combines a Diamond dome tweeter, a Continuum™ cone midrange driver, and twin 10-inch Aerofoil™ bass drivers to deliver effortless dynamics, remarkable detail, and deep, controlled bass. Bowers & Wilkins' innovative Biomimetic Suspension dramatically reduces unwanted air pressure and coloration, allowing the midrange to reproduce vocals and instruments with breathtaking transparency.
The distinctive all-aluminium Turbine™ Head provides a rigid, acoustically optimized enclosure for the Continuum midrange driver. Decoupled from both the bass cabinet and tweeter assembly, it minimizes unwanted resonances for exceptional clarity and realism. Advanced Matrix™ cabinet bracing further enhances structural rigidity, reducing cabinet coloration and allowing every musical detail to emerge naturally.
Finished in beautiful Walnut, the 801 D4 pairs timeless elegance with uncompromising performance. From the subtlest musical nuances to the most demanding orchestral passages, this remarkable loudspeaker delivers an immersive, lifelike listening experience worthy of the finest high-fidelity systems.
