Design Excellence

These ex-demonstration 804 D4 speakers represent six years of intensive research at Bowers & Wilkins' Southwater facility, bringing genuine diamond tweeter technology and studio-grade engineering to the most accessible floorstander in the legendary 800 Series. The reverse-wrap cabinet - previously exclusive to larger models - creates an acoustic and mechanical revolution that transforms what's possible from a metre-tall speaker.

Professionally maintained and meticulously inspected, our ex-demo pair showcases the flawless hand-applied finish that takes B&W craftsmen three days to complete. The Leather by Connolly detailing on the aluminium top plate speaks to obsessive attention to detail, whilst the elongated tweeter housing - now 30cm long - represents cutting-edge acoustic engineering. This Clearance Sale opportunity brings Worthing's finest craftsmanship to your listening room at an extraordinary value.

The Opportunity

The 804 D4 isn't simply the entry point to the 800 Diamond range - it's a complete reimagining of what a compact high-end speaker can achieve. Where the D3 made compromises, the D4 delivers. The new reverse-wrap cabinet reduces the front baffle profile whilst dramatically increasing rigidity. The downward-firing Flowport onto a constrained-layer damped aluminium plinth eliminates placement restrictions. The result? A speaker that works brilliantly just 20cm from rear walls - perfect for real British homes.

This generation introduces the Biomimetic Suspension system to the Continuum midrange driver - 80dB quieter than conventional designs at 1kHz. Combined with foam anti-resonance plugs in the twin Aerofoil bass drivers and the diamond tweeter's enhanced breathing space, you're getting technology that was £26,000 in the 802 D3, now refined and optimised for domestic spaces at a fraction of that investment.

Key Features

• Genuine diamond dome tweeter - Synthetic diamond's perfect stiffness for distortion-free highs to 35kHz
• Continuum cone FST midrange - Silver-woven material with exceptional self-damping properties
• Twin Aerofoil bass drivers - Syntactic foam core with variable-thickness carbon fibre skin
• Reverse-wrap cabinet construction - Continuous curved profile eliminates baffle diffraction
• Matrix bracing system - Interlocking internal panels create inert acoustic platform
• Solid Body Tweeter-on-Top - 30cm aluminium housing with two-point decoupling
• Biomimetic Suspension technology - Revolutionary quiet midrange mounting system
• Downward-firing Flowport - Turbulence-reducing dimpled surface with floor-coupled design

Performance Excellence

Listen to the 804 D4 and you'll understand why Abbey Road Studios, Capitol Records, and Sony Music choose 800 Series speakers as their reference. The diamond tweeter doesn't just extend to 35kHz - it maintains phase coherence and transient perfection throughout its range. Cymbal strikes shimmer with authentic metallic energy. Violins soar without a hint of grain. The treble isn't merely excellent; it's revelatory in its combination of delicacy and dynamics.

The Continuum midrange brings voices into your room with startling presence. Whether it's the breathy intimacy of Diana Krall or the power of Pavarotti, vocals possess that rare quality of sounding neither reproduced nor amplified - simply there. Bass performance belies the cabinet size, reaching a genuine 24Hz with the kind of control and texture that reveals the individual character of acoustic basses, the pitch definition of kick drums, the scale of concert venues. This is monitoring-grade accuracy delivered with musical soul.
