In the world of audio enthusiasts, especially those who have dedicated much of their lives to this pursuit, certain high-end brands often become household names. However, a potential pitfall in becoming too attached to these well-known brands is the risk of overlooking hidden gems. Today, we embark on a comprehensive exploration of a company that is no stranger to passionate audiophiles and their discerning ears. In the spotlight are the Bowers & Wilkins 805 D4 Signature compact speakers.

Meticulous Build Quality and Elegant Design

Regarding high-end audio equipment, build quality and design are often as important as sound performance. In the case of the Bowers & Wilkins 805 D4 Signature compact speakers, these aspects are nothing short of exceptional.

Craftsmanship Beyond Compare

When you look at the B&W 805 D4 Signature, you’re greeted with an undeniable sense of craftsmanship and attention to detail. Bowers & Wilkins, a company with a long history in the audio industry, has spared no expense in creating speakers that are not only acoustically exceptional but also visually striking.

Unique Cabinet Shape

One of the first things that sets these speakers apart is their unique cabinet shape. B&W introduced this distinctive design in the transition from the D2 to the D3 generation of the 800 series, and it continues to be a defining feature. While some might find the design unconventional, it serves a specific purpose. Unlike conventional speaker designs with flat front baffles for flush mounting of drivers, Bowers & Wilkins chose to place the drivers on the round housing part. This decision was driven by a desire for mechanical stability in the driver seat and improved resonance behavior of the housing. The bass-midrange driver of the 805 D4 Signature is strategically positioned within this curved housing, surrounded by a carefully shaped mounting ring.

Materials and Finishes

The attention to detail extends to the materials and finishes applied to these speakers. Bowers & Wilkins offers two distinctive finishes for the 805 D4 Signature models: “Midnight Blue Metallic” and “California Burl Gloss.” These finishes are far from mainstream and make a bold statement. Each cabinet undergoes a meticulous process, including multiple layers of varnish that result in a finish with a rich and deep appearance.

The Midnight Blue Metallic finish, in particular, is treated with the same finishing and painting process as the legendary Nautilus speakers from Bowers & Wilkins. This attention to detail not only adds a touch of exclusivity but also speaks to the brand’s commitment to craftsmanship.

Tweeter-on-Top Housing

The tweeter housing of the 805 D4 Signature features B&W’s iconic “tweeter-on-top” design. This design places the tweeter in a dedicated housing on top of the speaker cabinet. The housing is elongated, tapering towards the rear to minimize reflections from the back of the cabinet. This thoughtful design approach ensures that high-frequency sound radiates precision and clarity, enhancing the overall listening experience.

Luxurious Touches

What truly sets the B&W 805 D4 Signature apart is the attention to luxurious details. The tweeter-on-top housing is not simply painted or veneered; it is covered in full-grain Connolly leather, color-matched to the speaker’s finish. This premium touch not only adds to the visual appeal but also emphasizes the exclusivity of these speakers.

Crossover and Heat Management

The internal components of the 805 D4 Signature are no less impressive. The crossover network is mounted securely on the sturdy aluminum rear wall of the speaker. This design protects the sensitive crossover components from the vibrations generated by the bass-midrange driver and acts as an efficient heat sink. This ensures the crossover components maintain optimal performance, even during demanding, high-power applications.

Stands and Stability

Bowers & Wilkins offers the FS-805 D4 stands to complement these speakers, designed to match both the Signature and Standard versions of the 805 D4. These stands enhance the visual appeal and provide stability and support for the speakers. The stands include solid stainless steel spikes, round cap screws with plastic caps to protect delicate flooring, easy-grip nuts, and a proper wrench for secure attachment. These accessories further exemplify the brand’s commitment to quality and user experience.

Conclusion: Aesthetic Excellence and Uncompromising Build Quality

In conclusion, the Bowers & Wilkins 805 D4 Signature speakers are a testament to uncompromising build quality and exceptional design. Every aspect of these speakers, from their unique cabinet shape to their premium finishes and luxurious touches, speaks to the brand’s dedication to craftsmanship. These speakers deliver outstanding sound performance and stand as works of art that will enhance any audio enthusiast’s living space. Bowers & Wilkins has truly raised the bar regarding both aesthetic excellence and build quality with the 805 D4 Signature.

The Prestigious Signature Badge

Bowers & Wilkins, hailing from the United Kingdom, bestows the coveted “Signature” badge upon loudspeakers that demonstrate “complex technical and resulting sound improvements,” according to the manufacturer. In the storied history of Bowers & Wilkins, a company founded in 1966 and steeped in audio legends, this honor has only been conferred upon seven select loudspeaker models.

A Familiar Face with Subtle Cosmetic Changes

Upon first glance, the Bowers & Wilkins 805 D4 Signature may appear familiar, and you’re not mistaken. These speakers are rooted in the design and configuration of the “standard” 805 D4 model.

Proven Differences: The Unique Inverted Housing Shape

The distinctive shape of the 800 series might raise some eyebrows and spark discussions among audiophiles. But what is the rationale behind it? Most speaker designers opt for a flat front baffle to accommodate flush chassis mounting. However, Bowers & Wilkins embrace a different philosophy, citing advantages in mechanical stability for the driver seat and improved resonance behavior when the drivers are positioned on the rounded housing portion.

Venturing into Uncharted Aesthetic Territories

The striking high-gloss surface finishes distinguish the 805 D4 Signature models from their predecessors. These models are offered in “Midnight Blue Metallic” and “California Burl Gloss,” choices that defy the mainstream. The craftsmanship and aesthetics of the 805 D4 Signature leave an indelible impression of luxury and refinement.

Diving into the Driver Technology

In both versions of the B&W 805 D4 – Standard and Signature – a tweeter dome with a diameter of 25 millimeters, composed of the aforementioned (artificial) diamond material, plays a pivotal role in rendering music. It resides in B&W’s iconic “tweeter-on-top” housing, a design emblematic of its commitment to audio excellence.

Taking a Breath: The Bass Reflex Outlet

The bass reflex outlet, aptly named the “Flowport,” retains its original design to further reduce unwanted flow noise. The speaker includes foam plugs, allowing users to fine-tune the bass reflex opening to their preferences.

Elevated Aesthetics and Rigidity

The tweeter-on-top housing sits atop an aluminum cover plate, which, in the Signature model, is now connected to the main housing in an even more torsion-resistant manner through two additional fasteners. This structural enhancement contributes to reduced resonances and less distortion.

Meticulous Crossover Design

The crossover network within the 805 D4 Signature remains largely unchanged. It is securely mounted on the robust aluminum rear wall of the loudspeaker. This design protects the sensitive crossover components from the influence of the bass-midrange driver and serves as an efficient heat sink, ensuring optimal conditions for the components even under high-power demand. The crossover components continue to showcase the commitment to quality with features like an air coil, a Mundorf MCap Supreme SilverGold.Oil capacitor, and now four improved bypass capacitors.

Solid Foundation: The Stands

Bowers & Wilkins offers the same stands for both 805 D4 models, regardless of whether they are Signature or Standard. These stands provide added stability and include heavy-duty stainless steel spikes and caps to protect delicate flooring.

Sound Quality and Comparative Listening

Now, let’s circle back to my opening remarks. I must confess that I tend to have a soft spot for the underdogs in the high-fidelity world, often favoring them over the industry giants. However, the B&W 805 D4 Signature has managed to challenge my predispositions, proving once again that there are no absolutes in the world of audio and that being open to diverse experiences can lead to remarkable discoveries.

Elegance and Precision in the Bass

The B&W 805 D4 Signature defies expectations with its bass response. While compact, these speakers offer a linear, neutral bass that surprises listeners with its agility and precision.
