The Bowers and Wilkins 803 Diamond D4 Speakers are the most compact headed model, bringing all the technical advantages of a dedicated midrange enclosure โ the Turbine Head, with its decoupled midrange cone โ to a smaller footprint thatโs easily accommodated in any home.
Small Wonder
The 803 Diamond D4 may be notably more compact than the 801 D4 or 802 D4, but it still bristles with technical innovation, most obviously in its use of a three-box construction. Thanks to its turbine head enclosure, its 130mm (5-in) midrange cone is isolated from the impact of its bass cones.
Aerofoil Bass Cone
Our Aerofoil bass cone technology remains an outstanding solution to combining low mass and high stiffness in bass cones, thanks to its carbon-fibre skin and variable-profile foam core. Now, we have added the foam Anti-Resonance Plug for lower distortion and even cleaner bass from the 803 Diamond D4.
Biomimetic Suspension
Sometimes, making a big difference takes unconventional thinking. The new Biomimetic Suspension revolutionises midrange performance by greatly reducing the unwanted air pressure and colouration that a traditional fabric spider can generate. The result? the 803 Diamond D4 has midrange transparency that you wouldnโt believe.
The Science of Sound
Innovation is at the heart of everything we do. We question, we examine, we understand, and then we evolve. We use computer modelling to explore and reimagine every aspect of speaker design.
Step Up for More Power
The 803 D4 features all the most iconic ingredients in the 800 Series Diamond range, including that famous headed enclosure. It is, however, smaller than its other siblings. Step up to the 802 D4, and youโll get both larger 200mm (8-in) bass cones and a larger 150mm (6-in) midrange driver.
