Features
Diamond Dome Tweeter
Prized in highly specialised industrial applications, the unique properties of diamond make for a near-perfect tweeter material. Our diamond domes are grown like crystals in super-heated furnaces under laboratory conditions before being cut to produce our tweeter domes.
Solid Body Tweeter
Precisely milled from a single billet of aluminum to better resist resonance, the improved tweeter enclosure features an elongated form with a longer tube-loading system. You'll experience more open high frequencies from the diamond tweeter.
Continuum Cone
Continnum is a woven composite that blends control with flexibility. The result is breathtaking clarity. Hear voices, guitars and bass instruments with precision and transparency.
Biomimetic Suspension
Our all-new Biomimetic Suspension revolutionises midrange cone performance by greatly reducing the unwanted air pressure and coloration that a conventional fabric spider can generate. The result? Midrange transparency you wouldn’t believe possible.
Turbine Head
Hear the sound, not the cabinet. This all-aluminium enclosure is a phenomenally stiff and inert housing for the crucial midrange cone, carefully damped to avoid unwanted resonances and decoupled from the bass enclosure and the tweeter body. The result? The most realistic midrange yet.
Aerofoil Bass
Advanced computer modeling, carbon fiber and a syntactic core are used to produce a cone with maximum stiffness where it’s needed most. This optimised shape means the cone displays pistonic behaviour further up the audible range, producing precise, controlled and utterly lifelike bass.
Reverse Wrap Cabinet
The front and sides of the cabinet are formed in one continuous curve, held together with a spine of solid aluminium. The curved front means less baffling around the drive units so you'll enjoy greater dispersion and less cabinet reflection for a more holographic sound.
Aluminium top-plate
The all-new aluminium top section significantly upgrades the mechanical stiffness of the cabinet for reduced resonance and greater clarity.
Matrix Bracing
Interlocking solid plywood panels with aluminium bracing reinforce loudspeaker cabinet walls at key stress points. This reduces cabinet resonances so you can enjoy all of the fine midrange and bass details in your music and movies.
Leather by Connolly
The top of the speaker features an aluminium top-plate, covered in all-new Leather by Connolly trim. We use luxurious, full-grain black leather for Gloss Black and Satin Rosenut finishes, and a light grey leather for White and Satin Walnut.
Magnetic grille
Remains acoustically transparent while protecting the speaker's components.
Finishes
This model is available in Gloss Black, Rosenut, Satin Walnut and White.

803 D4 is our most compact model that makes use of all 800 Series Diamond technologies. 803 D4 steps up from 804 D4 by completely isolating the Continuum midrange driver in a separate enclosure called the Turbine Head. This all-aluminium enclosure is an inert housing for the midrange driver that avoids unwanted resonances and is decoupled from both the bass enclosure and the tweeter body. Cabinet stiffness has been increased with an Aluminium Plate that reinforces the top of the cabinet. Midrange performance has been dramatically improved with a new Biomemetic Suspension that replaces a conventional fabric spider with a groundbreaking innovation that reduces distortion behind the drive unit. The Solid Body Tweeter enclosure has been elongated, increasing air volume behind the diamond tweeter which improves the openness in high frequencies. The top section’s aluminium top-plate is covered in Leather by Connolly trim. We use luxurious, full-grain black leather for Gloss Black and Satin Rosenut finishes, and a light grey leather for White and Satin Walnut. Each new generation of 800 Series Diamond is a landmark event for Bowers & Wilkins. This is our benchmark and the most advanced range of loudspeakers we know how to make, equipped with our most sophisticated technologies and designed to deliver the upmost in sonic realism. The 800 Series Diamond is everything we know, and everything we are.
702 S3 is our 700 Series flagship: a state-of-the-art floorstanding speaker that defines standards for performance in its class. Its Carbon Dome tweeter is housed in a Solid Body Tweeter assembly, derived from 800 Series Diamond. That ensures even more realistic treble, while its decoupled midrange assembly, enhanced here with our revolutionary Biomimetic Suspension, provides outstanding midrange transparency and openness. And thanks to its downward-firing port configuration and its trio of Aerofoil Profile bass cones, 702 S3 can deliver bass that’s both profoundly deep and endlessly articulate. If you want the best in the series, this is it.
705 S3 is our ultimate 700 Series bookshelf speaker, a no-holds-barred celebration of excellence able to highlight all the subtle nuances in your music that other speakers miss. Its Carbon Dome tweeter is housed in a redesigned Solid Body Tweeter-on-Top enclosure used in 800 Series Diamond products. That joins a subtly curved baffle endowed with a ‘pod’ housing for its Continuum Cone bass/midrange driver, ensuring that you hear less of the speaker’s cabinet, and more of the music you love.
If space is at a premium, 704 S3 provides the answer. The slimmest floorstanding loudspeaker Bowers & Wilkins makes, it still packs a mighty punch, with its twin Aerofoil Profile bass drivers ensuring ample extension and scale. Thanks to its decoupled Continuum cone FST midrange driver – enhanced here with our Biomimetic Suspension – it’s capable of delivering crystal clear midrange performance.
