Bowers & Wilkins 802 D4 Floorstanding Speaker
26 000,00 €
Bowers & Wilkins 802 D4 is a three-way floorstanding speaker designed for reference-level stereo and home cinema systems. The separate Turbine Head enclosure reduces the influence of the bass drivers on the midrange. Two 200 mm Aerofoil drivers reproduce low frequencies, while a 25 mm diamond dome handles the treble. The amplifier must remain stable when impedance falls to 3.0 ohms.
Bowers & Wilkins 802 D4 is a three-way floorstanding speaker designed for reference-level stereo listening and home cinema systems. Its bass-reflex enclosure houses a three-way driver configuration, while the specified minimum impedance is 3.0 ohms. The minimum order quantity is two units.
Enclosure Design
The midrange driver is installed in a separate Turbine Head enclosure. This mechanically isolated design separates it from the bass drivers and helps reduce mechanical interaction between them.
An aluminium top plate is used to increase the structural rigidity of the cabinet. It also provides the mounting location for the Leather by Connolly cabinet trim.
Driver System
High frequencies are reproduced by a single 25 mm diamond-dome tweeter. A separate 150 mm driver with a Continuum cone handles the midrange.
The midrange driver also incorporates FST and Biomimetic Suspension technologies. Its decoupled construction helps limit interference transmitted by the bass drivers, allowing the midrange section to operate in its own dedicated enclosure.
Low frequencies are reproduced by two 200 mm drivers with Aerofoil cones. This three-way arrangement assigns each principal frequency region to a dedicated type of driver.
Choosing an Amplifier and Speaker Cable
The speaker connects to a power amplifier or integrated amplifier using speaker cable. Recommended amplifier power is 50-500 W into an 8-ohm load.
This recommendation applies when programme material is played without signal clipping. An underpowered amplifier driven beyond its limits can produce a clipped signal even before particularly high listening levels are reached.
Although the nominal impedance is 8 ohms, the minimum impedance falls to 3.0 ohms. The chosen amplifier must therefore remain stable when presented with this load.
The maximum recommended cable impedance is 0.1 ohm. For a longer cable run, choose a lower-impedance cable and avoid unnecessary connections that could add resistance.
Placement and Initial Setup
Begin by positioning this bass-reflex speaker with some space between the cabinet and the surrounding walls. Listen from the main seating position and assess how evenly the bass is reproduced throughout the relevant frequency region.
Placing the speaker too close to a wall may reinforce certain low frequencies. Adjust the distance in small steps, making the same change for both the left and right channels so that the system remains balanced.
Aim the speakers towards the listening position, then adjust their angle while listening to the focus of the central image. Keeping both speakers equally distant from the primary listening position helps maintain a symmetrical stereo soundstage.
The stated dimensions are 413 × 1218 × 602 mm, but the order of the axes is not defined. Before installation, check the available space in all three directions rather than assuming which figure represents width, height or depth.
Because a net weight figure of 88.10 kg is listed, confirm what that figure applies to before delivery and plan how the speakers will be moved safely into position.

FAQ
What is the minimum-order requirement?
The store specifies a minimum order of two units. This does not, by itself, confirm that the displayed price is for a pair.
What type of amplifier should I choose?
Choose a model capable of delivering 50-500 W into 8 ohms. It must also remain stable when the speaker impedance drops to 3.0 ohms.
How do I connect the speaker to a stereo amplifier or AV receiver?
Use speaker cable with a total impedance no higher than 0.1 ohm. Maintain the same polarity for both channels when making the connections.
Where should I start when finding the right position in the room?
Start with space between the speakers and the walls, using a symmetrical layout. Fine-tune their position according to the evenness of the bass at the listening seat.
What should I plan before the speakers are delivered to the listening room?
Check doorways, corners and the dimensions of the final installation area. As the listed net weight is 88.10 kg, confirm what this figure applies to before delivery and plan how the speakers will be moved.
