Bowers & Wilkins 804 D4 Studio-Grade Diamond Floorstanding Loudspeaker, Gloss Black – Pair

Description This is not just another speaker range. Each new generation of 800 Series Diamond is a landmark event for Bowers & Wilkins. This is our benchmark, our icon; the most advanced range of loudspeakers we know how to make, equipped with all of our most sophisticated technologies and designed to deliver the upmost in sonic realism. For us, the800 Series Diamond is everything we know, and everything we are. FeaturesBowers & Wilkins 800 Series Diamond. Excellence. Evolved.How do you improve on the world’s most successful and iconic range of high-end loudspeakers? It’s a challenge that has occupied the past six years for the finest minds at SRE, home of the world-renowned Bowers & Wilkins engineering team. Their solution is to combine continuous improvement of every component in each design with innovative and proprietary technology that re-imagines the fundamental basics of a conventional loudspeaker drive unit: the new, unique and revolutionary Biomimetic Suspension. The new 800 Series Diamond range continues to feature seven models, beginning with the two-way 805 D4 stand-mount speaker. That’s joined by a series of three-way floorstanding models, including the 804 D4, 803 D4 and 802 D4. For the flagship model in the range, Bowers & Wilkins is pleased to reintroduce an iconic name to its portfolio, with the launch of 801 D4 to replace the existing 800 D3. For home theatre use, the HTM81 D4 and HTM82 D4 provide a pair of high-performance center channel speakers to complete the range.Industry defining performanceThe new 800 Series Diamond features many product developments and exciting innovations that evolve the performance of our flagship range and further establish the 800 Series Diamond as the finest loudspeakers on the market. The best just got better.SUPPORTING PRODUCT FEATURES• Biomimetic Suspension• Continuum cone• Diamond dome• Turbine Head• Reverse wrap cabinet• MatrixWhere music beginsMusic you will soon hear everywhere was heard first on 800 Series Diamond speakers. The range is the choice of artists and top recording studios globally, such as Abbey Road and Skywalker Studios.SUPPORTING MESSAGES• True Sound• As the artist intended• Abbey Road StudiosProprietary technologyThe 800 Series Diamond features many proprietary technologies that raise the bar for audio excellence – Diamond dome Tweeters, Continuum cones, Matrix cabinets – and cascade into other product categories.SUPPORTING PRODUCT FEATURES• Diamond dome• Continuum cone• Matrix• Biomimetic Suspension• Reverse wrap• FST midrangeBold designAlthough we always aim for acoustic excellence, we also create designs that are beautifully crafted, meaningful and elegant. The 800 Series Diamond is no exception, with its distinctive proportions, fastidious construction and luxurious detailing.SUPPORTING PRODUCT FEATURES• Leather by Connolly• Reverse wrap cabinetry adopted across entire range• Four elegant finishes• Anodised Tweeter-on-Top with etched finishingTurbine HeadOur all-aluminum Turbine Head is an inert housing for the midrange cone that avoids unwanted resonances and is decoupled from both the bass enclosure and the tweeter body.Solid Body TweeterOur new Solid Body Tweeter-on-Top housing features an elongated form with a longer tube loading system, producing an even more free and open sound with high frequenciesReverse Wrap CabinetOur cabinets are formed from one continuous curve, backed by a spine of solid aluminum, so sound dispersion is improved and cabinet reflection is reduced.Matrix™Every model in the new 800 Series Diamond benefits from an upgraded Matrix™ design, reducing resonance and creating a more believable soundstage.Aluminum Top PlateEvery stereo model in the new 800 Series Diamond range has a significantly upgraded cabinet design with an all-new aluminum top section for even greater stiffness.Aluminum PlinthThe 804 D4 now joins the other floor-stand-ing models in the range by offering a down-wards-firing Flowport, exiting on to a new, stiffer solid aluminum plinth complete with a constrained layer steel damping sheet offering a rock-solid foundation that controls unwanted resonance.Aluminum Driver PodsDrive units are housed in stiff aluminum pods mounted to the baffle of the speaker. This both secures and decouples the driver from the enclosure.Diamond dome tweeterIts unique stiffness-to-lightness ratio makes diamond the perfect tweeter material. Our diamond domes are capable of unrivaled acoustic detail, naturalism and spaciousness.Continuum ConeVoices and instruments are delivered with purity and precision, thanks to the smooth, accurate Continuum coneDecoupled Midrange AssemblyEvery 800 Series Diamond loudspeaker aside from the 805 D4 has a decoupled midrange cone ensuring minimal interference from the loudspeaker’s bass driversBiomimetic SuspensionOur all-new Biomimetic Suspension revolutionizes 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 possibleAerofoil bass coneThe result of advance computer modelling, Aerofoil is a composite bass cone with a varying thickness designed to offer maximum stiffness where it is most needed while preserving a low mass – thanks to its carbon-fiber skin and light syntactic foam core.CrossoverAll stereo models in the new 800 Series Diamond range now use rear-mounted crossover designs mounted on stiff aluminum spines. This isolates the sensitive capacitors from the unwanted effects of air pressure within the enclosure and makes for a very effective heatsink to ensure optimum performance when in use SpecificationsDiamond tweeter Solid body Tweeter-on-Top Continuum™ cone FST Anti-Resonance plug Biomimetic Suspension Matrix™ Aerofoil™ cone bass units FlowportDescription 3-way vented-box systemDrive units 1x ø25mm (1in) diamond dome high-frequency 1x ø130mm (5in) Continuum cone FST midrange 2x ø165mm (6.5in) Aerofoil cone bass unitsFrequency range 20Hz to 35kHzFrequency response 24Hz to 28kHz ( /-3dB from reference axis)Sensitivity 89dB (on axis at 2.83Vrms at 1m)Harmonic distortion 2nd and 3rd harmonics (90dB,1m on axis) Nominal impedance 8Ω (minimum 3.0Ω)Recommended amplifier power 50W – 200W into 8Ω on unclipped programmeMax. recommended cable impedance 0.1ΩDimensions Height: 1071mm Width: 306mm Depth: 391mmNet weight 36.85kg
