Bowers & Wilkins 805 D4 Signature Speaker Pair

The Bowers & Wilkins 805 D4 is the most compact model in the 800 Series Diamond range — yet it embodies the same uncompromising engineering and acoustic innovation as its larger siblings. Designed for smaller spaces or dedicated listening rooms, it offers remarkable transparency and musicality in a refined, elegant form.

At the core of the 805 D4 is the Diamond Dome tweeter, renowned for its crystalline high-frequency detail. Mounted in the Solid Body Tweeter-on-Top assembly, it delivers outstanding dispersion and minimal resonance. The Continuum™ cone bass/midrange driver ensures an open, balanced sound with smooth transitions between frequencies, while the Anti-Resonance plug enhances linearity and reduces distortion.

Internally, Matrix™ bracing provides exceptional cabinet rigidity, and the Flowport™ design optimizes airflow for clean, articulate bass response. Despite its compact size, the 805 D4 offers a spacious soundstage and astonishing realism — making it a true reference-class bookshelf speaker.

Offered in exquisite finishes such as California Burl Gloss, Midnight Blue Metallic, and Black, it’s a perfect fusion of sonic performance and timeless craftsmanship.
