Bowers & Wilkins - 804 D4 Diamond 1" Diamond Tweeter, 5" Midrange, Dual 6.5" Woofer Floorstanding Speaker (each) - Gloss Black
About this product
The 804 D4 is the most compact floor standing speaker in the 800 Series Diamond range. Its new reverse-wrap cabinet follows the proven design principles established by its larger siblings and its new plinth ensures rock-solid, accurate bass response. 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.
Color
Gloss BlackDiamond 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.
Decoupled Midrange
Energy produced by bass drivers can travel through the cabinet and degrade midrange performance. Like a shock absorber, we've decoupled the midrange from the cabinet to reduce this distortion and improve clarity.
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.
