What the New 800 Series Diamond D5 Is and Why It Matters
The Bowers Wilkins 800 Series Diamond D5 is a redesigned premium speaker lineup that refines the brand’s flagship loudspeaker design with upgraded acoustic engineering, reworked cabinet construction, and new finishes, aiming to deliver reference-grade sound for both high-end home listeners and professional studios. Announced at HIGH END Vienna in the brand’s 60th year, the D5 generation replaces the D4 range and marks the fifth iteration of the Bowers Wilkins 800 Series to use the company’s Diamond Dome tweeter technology. The family now spans seven models, beginning with the compact two-way 805 D5 stand-mount and extending through four floorstanding high-end audio speakers plus two center-channel options for home theater. According to Bowers & Wilkins, the new 800 Series Diamond D5 is intended as “the ultimate embodiment of John Bowers’ True Sound philosophy,” with each model designed to interfere with the music as little as possible.
Seven Speakers, One Flagship Philosophy
The Bowers Wilkins 800 Series Diamond D5 range has been structured to cover distinct roles and room sizes while keeping a unified, reference-led approach. It starts with the 805 D5 stand-mount speaker, a two-way design for smaller spaces or nearfield listening. Above it sit four three-way floorstanders: 804 D5, 803 D5, 802 D5 and the flagship 801 D5. The 803 D5 is the most compact model to feature the brand’s Turbine Head midrange enclosure, while the 804 D5 opts for a more conventional silhouette aimed at discreet installations. Home cinema buyers are served by the HTM81 D5 and HTM82 D5 center-channel speakers, built to match the tonal balance of the main speakers. Bowers & Wilkins positions the 801 D5 as the reference for studios and serious listeners, using Diamond Dome tweeters, Continuum cone midrange drivers and Aerofoil bass units in a three-way vented-box design.
Acoustic and Mechanical Upgrades in the D5 Generation
While the D5 series keeps the familiar Diamond Dome tweeter, Bowers & Wilkins has reworked the acoustic and mechanical platform to reduce distortion and improve resolution. The brand has migrated performance parts from its 800 Series Signature models into the Bowers Wilkins 800 Series Diamond D5, aiming for more openness, better dynamics and lower noise. Residential Systems reports that the research team at the Southwater Research Establishment used extensive measurement and simulation work to identify cabinet-based enhancements, including greater use of aluminum and new Space Frame Bracing at the rear of the cabinets to cut enclosure coloration. In the 804 D5, a new internal aluminum enclosure isolates the Continuum Cone FST midrange assembly, helping preserve clarity through the critical vocal band. These changes underscore Bowers & Wilkins’ goal of providing high-end audio speakers that behave as neutral, transparent transducers for reference listening.
Cabinet Engineering and Evolving Flagship Aesthetics
The D5 redesign is as much about industrial design as it is about drivers and crossovers. Bowers & Wilkins has tightened production tolerances across the range, reducing visible panel gaps, concealing fixings and improving paint processes for a more seamless flagship loudspeaker design. All speakers continue to be made in Worthing with an emphasis on craftsmanship and precision. A fresh finish palette marks a clear break from the D4 generation: Stealth Black and Warm White are joined by Light Walnut and an all-new Dark Walnut inspired by the limited 801 Abbey Road edition. The Dark Walnut option combines darker metal detailing with Leather by Connolly trim, tilting the aesthetic toward modern luxury furniture. Subwoofer finishes in the DB Series also now align with Stealth Black and Warm White, helping system builders create visually coherent premium audio setups around the 800 Series Diamond D5 models.
Pricing Tiers and What the Lineup Means for Premium Buyers
With the 800 Series Diamond D5, Bowers & Wilkins is staking an ambitious claim on the premium speaker lineup segment across multiple budget levels within high-end audio. Digital Trends notes that prices for the stereo models start at £10,000 for the 805 D5 and rise to £43,000 for the flagship 801 D5, while Man of Many reports that Australian pricing spans AUD $19,900 to AUD $84,900 per pair for the stereo models. This spread gives buyers a clear path from compact stand-mount to studio-grade floorstander without leaving the 800 Series family. For audiophiles, it means the sonic and aesthetic language of the top 801 D5 trickles down through more attainable models like the 803 D5 and 804 D5. For studios and integrators, the matching center speakers and finishes simplify building coherent, reference-focused multichannel systems around a single flagship platform.
