B&W 804 D4 Floor-standing speaker

For listeners who crave the performance of an 800 Series Diamond floorstander but prefer a more conventional aesthetic, the 804 D4 is the perfect choice. Its new cabinet and plinth make it our best-performing 804 yet.

*Classic quality

804 D4 is perhaps more conventional in appearance than other floorstanders in the 800 Series Diamond range, but its every bit as sophisticated. Its new Reverse-Wrap cabinet is both a mechanical and acoustic revolution in its class, and its new plinth ensures rock-solid, accurate bass response too.

*Aluminium top-plate

Every stereo model in the new 800 Series Diamond range has a significantly upgraded cabinet with an all-new aluminium top-plate. This also provides a perfect mounting point for all-new Leather by Connolly trim, with luxurious black leather for dark cabinets and light grey for lighter finishes.

*Reverse Wrap cabinet

Instead of a conventional loudspeaker box, our cabinets are made from a continuous curved section of wood, with the drive units mounted at the heart of the curvature. This stiffer, more inert structure resists mechanical resonances far better and also ensures better dispersion of sound.

*Get a Head

804 D4 is the entry-level floorstanding model in the 800 Series Diamond range. Step up to 803 D4 and youll find larger bass drivers (180mm, 7in) plus, crucially, the addition of a Turbine Head enclosure for the 130mm (5in) midrange cone, which adds even more spaciousness to the sound.
