A Trusted Brand in the Music Industry
Bowers & Wilkins, or B&W, has established a strong presence in the professional audio world, with its speakers frequently found in recording studios, including the iconic Abbey Road studios in London. This association underscores the brand’s reputation for quality and reliability.

What’s New in the D4 Series
While at first glance, it may appear that not much has changed between the D3 and D4 series, a closer examination reveals significant enhancements. B&W has made several refinements to boost the speaker’s performance and aesthetics.
- Biomimetic Suspension: One standout improvement is the biomimetic suspension of the midrange driver, which has significantly enhanced midrange clarity, addressing an area of previous criticism.
- Streamlined Design: The overall design of the D4 series appears more coherent and refined, making it visually appealing in any listening environment.
Notable Features of the 803 D4
The B&W 803 D4 boasts several features that set it apart:
- Diamond-Coated Tweeter: The 803 D4 features a diamond-coated tweeter, a hallmark of B&W’s high-end speakers, offering extended frequency response and improved treble energy. The tweeter is housed in its dedicated tube to minimize interference with other drivers.

- Bass Reflex Port: The downward-directed bass reflex port further enhances the speaker’s low-frequency performance.


Practical Considerations
While the 803 D4 has an efficiency rating of 88.5 decibels, indicating that it can deliver impressive sound levels, it requires a robust amplifier due to its nominal 4-ohm impedance and impedance minimum of 2.9 ohms at 100 Hz. Adequate power is essential for optimal performance.
In the world of high-end audio, the Bowers & Wilkins 803 D4 speakers are not just renowned for their exceptional sound performance; they also stand out for their unmatched build quality. This review takes a closer look at the craftsmanship and construction of these speakers, shedding light on what sets them apart in terms of build quality.
Precision and Expertise
Bowers & Wilkins has a long-standing reputation for its meticulous attention to detail and uncompromising commitment to quality. The 803 D4 is a testament to this heritage. Every element of these speakers reflects precision and expertise, starting with the materials used in their construction.

Materials of Distinction
- Industrial Diamond-Coated Tweeter: The most striking feature is undoubtedly the diamond-coated tweeter. Bowers & Wilkins is unique in offering this technology in its price range. Diamonds, being incredibly hard, provide a superlative surface for audio transduction. The tweeter, housed in its elongated tube, not only looks distinctive but also contributes to the speaker’s longevity and performance.
- Metal Midrange Driver: The midrange driver, encased in its own “turbine head” tube, is another hallmark of the 803 D4. Crafted from metal and refined over the years, it exemplifies Bowers & Wilkins’ commitment to optimizing driver design for exceptional sound reproduction.
- Aerofoil Membrane: The woofers in the 803 D4 have undergone a significant transformation. These 18-centimeter drivers now feature an Aerofoil membrane that enhances their performance. This material, combined with advancements in the neodymium magnet drive, contributes to precise and efficient bass output.
Exquisite Cabinet Construction
The cabinet housing these meticulously engineered drivers is where the 803 D4 truly shines:
- Multiplex Wood: The bass housing of the speaker is crafted from multiplex wood. This material is bent into shape using a complex process, ensuring both structural integrity and resonance control.
- Metal Skeleton: The internal structure of the 803 D4 features a sophisticated metal skeleton. This skeleton provides vital support to the drivers and cabinet, maintaining stability and reducing unwanted vibrations that can color the sound.
- Leather Accents: An elegant touch is the leather covering on the top of the bass housing. This attention to aesthetics not only adds to the speaker’s visual appeal but also serves to dampen vibrations and resonances, contributing to cleaner sound.

Attention to Detail
While the choice of materials and overall construction are impressive, it’s the finer details that truly elevate the 803 D4’s build quality:
- Driver Isolation: Each driver—tweeter, midrange, and woofer—has its dedicated chassis within the cabinet. This innovative design prevents interference among the drivers, ensuring that they work harmoniously to reproduce sound.
- Quality Assurance: Bowers & Wilkins maintains stringent quality control throughout the manufacturing process. Each speaker undergoes rigorous testing to meet the brand’s exacting standards.
