Description
Bowers & Wilkins 803 D4 Floorstander (Pair)
803 D4 is the most compact of the headed 800 Series Diamond floorstanders. Its smaller footprint makes it easier to accommodate than the 801 D4 or 802 D4, but it still uses a dedicated midrange enclosure rather than placing every driver in one box.
The Turbine Head and decoupled midrange cone help keep voices and instruments focused, while the Diamond tweeter and Matrix cabinet provide the detail and control expected from the series.
It is a strong choice when the room can support a high-end tower but not the physical scale of the larger 800 Series models.
