The 802 D4 shares its proportions and much of its engineering DNA with the flagship 801 D4 — offering the same reference-level performance philosophy in a slightly more accessible package, without compromising on what makes Bowers & Wilkins the choice of professional studios worldwide. 

At the top, a solid-body Diamond Dome tweeter reproduces the highest frequencies — cymbals, strings, vocal breath — with exceptional precision. Diamond is used here because it's the stiffest material practical for this application, meaning it responds instantly and accurately without the distortion softer materials introduce, even at high volume. 

Just below sits the signature Turbine Head, a solid-aluminium enclosure housing the midrange driver in isolation from the rest of the cabinet. This is the same design used in the 801 D4, and it's the reason vocals and instruments through this speaker sound so remarkably natural and free of vibration-induced blur. 

Handling the low end are dual 10-inch Aerofoil bass drivers, engineered to deliver deep, controlled, textured bass rather than the loose boom common in lesser speakers — you'll hear the difference between a kick drum and a bass guitar, not just volume. 

The 802 D4 is a genuine three-way floorstanding reference speaker for anyone who wants 800 Series performance as the anchor of a serious stereo or home theatre system.
