The excellence of the 800 Series in a compact Signature format
The Bowers & Wilkins 805 D4 Signature represents the most refined evolution of the renowned 800 Series Diamond standmount speaker. This Signature version is designed to offer a superior level of acoustic performance and handcrafted finish, with select components and targeted crossover optimizations.
The result is a bookshelf speaker capable of combining absolute transparency , extreme micro-detail and a reference three-dimensional soundstage, maintaining a compact format perfect for high-end domestic environments.
Designed for high-end hi-fi systems, the 805 D4 Signature is for those who want a purist listening experience, with a unique aesthetic that immediately sets it apart from the standard version.
Diamond technology and optimized Reverse Wrap cabinet
The 805 D4 Signature uses a 25mm Diamond Dome tweeter housed in the renowned solid aluminium tweeter-on-top , decoupled from the cabinet to reduce vibration and colouration. The mid/bass is handled by the renowned 165mm Continuum™ driver , mounted in a Reverse Wrap cabinet stiffened by an internal aluminium matrix.
The crossover has been further optimized with selected components to ensure greater transparency and accuracy in the frequency response. The rear-firing reflex system with Flowport technology contributes to a controlled and articulated low range, maintaining tonal coherence and speed.
The result is a 2-way speaker that offers a neutral, dynamic and incredibly natural sound reproduction, ideal for high-level amplification.
