&W 801D4 Overview
There is no question that a lot of time and effort has gone into designing this unique midrange system, and the results are truly amazing. Patricia Barber's soft, easy-Jazz track "Shall We Dance" on Tidal is a perfect example of the 801 D4's ability to deliver an uncannily accurate representation of the music. The vocals and the nimble bass line are perfectly placed centre stage, with an overall impact and clarity that makes you want to finger-click your way through the track.
Moreover, it has been engineered to deliver a more realistic soundstage with less diffraction, thanks to the cabinet's reverse-wrap design and a Flowport that extends the cone of each driver, enabling the driver to move in and out of its enclosure as if they were an airplane wing.
The new cabinet designs, together with the aforementioned improvements to driver architecture and the use of a high-quality crossover, make the 801 D4 the most advanced B&W speaker to date, combining the highest levels of quality in terms of both fidelity and design. It's a true reference loudspeaker that will be judged for many years to come, and its unparalleled design is a real indicator of B&W's innate creativity.
B&W 801D4 Features
Bowers & Wilkins has long been the loudspeaker brand that sets the bar when it comes to innovation and original thinking. Their latest flagship speaker, the 801 D4, is their most dynamic and innovative model to date.
Among its many features, the 801 D4 showcases the company's most innovative driver architecture yet. Its drivers are optimized to deliver their full potential, with no limitations imposed by mechanics or amplification capabilities, while the cabinet has been completely redesigned to maximize rigidity and reduce diffraction, resulting in a more believable soundstage.
The 801 D4's woofers, for example, feature diaphragms in a composite "sandwich" construction with carbon fiber on top of rigid foam material. The idea is to achieve as close to a pure piston movement as possible, with minimal break-up along the suspension as the diaphragm moves in and out of the driver.
They also have a new anti-resonance plug in the voice coil that reinforces the voice coil and prevents it from flexing, which should improve the driver's longevity and performance at all sound pressure levels.
This enables the 801 D4's driver complement to produce super clean bass reproduction at all levels. Its downward-firing port, exiting onto a new stiffer solid aluminum plinth with constrained layer steel damping, helps ensure that the speaker's foundation is rock-solid and offers a controllable resonance level, while the Flowport has also been enhanced with upgraded spikes and feet.
B&W has used its Matrix bracing assembly in some models over the years, but with 801 D4 they have taken it to another level, reinforcing the entire cabinet wall internally to minimize resonance and create a more realistic soundstage. The new design uses interlocking panels that are fitted to all the corners and sides of the cabinet, with the result being a more stable design that reduces vibration and enhances performance.
The new Biomimetic Suspension technology revolutionizes midrange performance by reducing the pressure and coloration caused by traditional fabric spiders, resulting in a more transparent, natural-sounding midrange.
