Bowers & Wilkins 804 D4 Floor Standing Speakers - (Pair)
Overview
Some listeners want the performance of an 800 Series Diamond floorstander without a cabinet that dominates the room, and the 804 D4 is aimed squarely at them.
The Bowers & Wilkins 804 D4 is a 3-way vented-box floor-standing loudspeaker with a 25mm Diamond dome tweeter in a Solid Body Tweeter-on-Top housing, a 130mm Continuum cone FST midrange and two 165mm Aerofoil cone bass units. Bowers & Wilkins says its new cabinet and plinth make it the best-performing 804 yet.
Frequency response is 24Hz to 28kHz (±3dB) with 89dB sensitivity and an 8Ω nominal impedance (3.0Ω minimum). Bowers & Wilkins recommends 50W to 200W into 8Ω on unclipped programme.
Simcoe Audio Video Insight
At 1071mm tall and 36.85kg each, the 804 D4 is far easier to place than the larger models in the range, but it still benefits from space behind and beside it to work properly. We are happy to talk through speaker placement and amplifier matching for your room.
More Info
Why the Bowers & Wilkins 804 D4 Stands Out
Diamond Dome Tweeter
A 25mm Diamond dome in a Solid Body Tweeter-on-Top housing handles the high frequencies up to 35kHz.
Continuum Cone FST Midrange
A 130mm (5 in) Continuum cone FST handles the midrange in this 3-way design.
Biomimetic Suspension
Bowers & Wilkins says this suspension greatly reduces the unwanted air pressure and coloration that a traditional fabric spider can generate.
Twin Aerofoil Bass Units
Two 165mm (6.5 in) Aerofoil cone bass units and a Flowport deliver a frequency response of 24Hz to 28kHz (±3dB).
New Cabinet and Plinth
Bowers & Wilkins says the new cabinet and plinth make this its best-performing 804 yet.
Moderate Amplifier Demands
Rated at 89dB sensitivity with a recommended 50W to 200W into 8Ω.
Buyer's Guide
Who It's For
- The Listener With a Moderate-Sized Room: wants 800 Series Diamond performance from a floorstander 1071mm tall.
- The Conventional-Aesthetic Buyer: prefers a more traditional look than the larger flagship models, as Bowers & Wilkins describes it.
- The Mid-Power Amplifier Owner: has an amplifier in the 50W to 200W range Bowers & Wilkins recommends.
How It Compares
The 802 D4 steps up to a 150mm Continuum cone FST midrange and two 200mm Aerofoil bass units, with a 1218mm tall cabinet and a recommended 50W to 500W. For a smaller footprint, the 805 D4 is a 2-way stand-mount speaker that is 440mm tall.
