Bowers & Wilkins Diamond 805 D4
The 805 D4 stand-mount loudspeaker is the most compact model in the 800 Series Diamond™ range, but it’s still packed with advanced technologies, including the Diamond dome tweeter and the Solid Body Tweeter-on-Top.
Little Diamond
805 D4 might be smaller than its floorstanding siblings, but it’s no lightweight: its beautifully constructed Reverse-Wrap cabinet, stiff aluminium bass pods and 165mm (6.5in) Continuum™ mid-bass cone afford it exceptional bass extension and scale for a relatively compact speaker.
Diamond dome tweeter
One of the most significant B&W accomplishments over the past two decades, the ultra-stiff, supremely accurate Diamond dome tweeter is the perfect combination of low mass, exceptional stiffness and outstanding accuracy.
Solid Body Tweeter assembly
The newest Solid Body Tweeter-on-Top housing features an elongated form with a longer tube-loading system, producing an even more free and open sound with high frequencies. The carefully decoupled housing is milled from a single solid block of aluminium to better resist resonance.
Rear-mounted crossover
The new reverse-wrap orientation of the cabinet on 805 D4 means its sensitive crossover components can placed inside their own, dedicated space within the cabinet, which has critical benefits to both performance and serviceability. The speaker terminals have also been upgraded.
Go large
Why step up from 805 D4 to 804 D4? First, 804 D4 is a three-way speaker, with twin 165mm (6.5in) Aerofoil™ bass cones – and that has huge benefits to its power and scale. Second, as a three-way speaker, it includes a dedicated midrange cone, so voices and other details will sound more accurate.
B&W provides solutions for any demand and application – be it the stage direction studio of a philharmonic venue or the acoustic supply of a home cinema. Tranquil and mature sound meet excellent workmanship.
We have a wide range of B&W speakres available for demonstration in our HiFi studios in Berlin-Kreuzberg. We look forward to your visit!
