B&W 803 D4 Reference Speaker

B&W's most compact headed model brings all of the technical advantages of a dedicated midrange enclosure - the iconic Turbine Head - to a smaller footprint that's easily accommodated in any home. Small doesn't mean compromised, either: 803 D4 still bristles with technical innovation throughout.

Matrix bracing uses interlocking panels to reinforce loudspeaker cabinet walls in all directions internally, reducing resonance and creating a more believable soundstage. The Matrix assembly in 803 D4 is our best yet, ensuring optimum scale, power and intelligibility.

Innovation is at the heart of everything B&W does. They question, they examine, they understand and then they evolve. They use computer modelling to explore and reimagine every aspect of loudspeaker design.

803 D4 features all the most iconic ingredients in the 800 Series Diamond range including, of course, that famous headed enclosure. It is, however, smaller than its other siblings. Step up to the 802 D4, and you’ll get both larger 200mm (8-in) bass cones and a larger 150mm (6-in) midrange driver.

• Diamond Dome Tweeter – Offers world-class treble accuracy and imaging clarity, with a breakup frequency beyond 70kHz.
• Solid Body Tweeter-on-Top – Milled from solid aluminum to eliminate resonance and improve high-frequency openness.
• Continuum™ Cone FST™ Midrange Driver – Ensures transparent and lifelike vocal and instrumental reproduction with minimal coloration.
• Turbine™ Head Enclosure – Decoupled, all-aluminum housing isolates the midrange for superior clarity and reduced cabinet interaction.
• Reverse Wrap Cabinet – Curved wood structure enhances rigidity, disperses resonance, and improves sound dispersion and staging.
• Enhanced Matrix™ Bracing – Interlocking internal panels with reinforced metal sections deliver exceptional cabinet stiffness and sonic integrity.
• Twin Aerofoil™ Bass Drivers in Aluminum Pods – Carbon-fiber skinned drivers housed in solid aluminum structures provide deep, fast, and highly controlled bass.
• Anti-Resonance Plug – Reduces distortion in the bass drivers for cleaner, tighter low-frequency performance.
• Flowport™ Technology – Minimizes air turbulence and noise from the rear port for smoother, more articulate bass output.
• Compact, Elegant Design – Combines flagship-grade performance with a footprint suitable for premium stereo or home theatre environments.
