Bowers and Wilkins (B&W) 805D4 Signature (pair)

805 D4 SignatureThe 805 D4 Signature standmount loudspeaker is compact and powerful. It features fully optimized technologies, including that all-important Diamond Dome tweeter and Solid Body Tweeter-on-Top. It’s proof positive that small can still be beautiful. Stands NOT included.   Key Features 1" Diamond Dome Tweeter Solid body Tweeter-on-Top 6.5" Continuum cone bass/mid Matrix™ Flowport Signature TechnologyAs with preceding generations of Signature, both 805 D4 Signature ​and 801 D4 Signature employ a series of carefully engineered ​audio upgrades designed to deliver the best possible sound.​​These changes take in structural modifications designed to​ improve mechanical behavior and acoustic transparency, drive unit enhancements aimed at delivering even greater resolution and crossover upgrades that ensure fully optimized performance from the complete system.​​None of these components will be made available for ‘retro-fit’ ​ to current products or incorporated as a running change into ​existing 800 Series Diamond products.   Aluminum Top-PlateA new aluminum top plate features a series of machined-out holes in the structure, strategically positioned to change the resonant frequency of the aluminum.​      New Tweeter Grille MeshBoth models introduce a new design of tweeter grille mesh. ​The new grille mesh offers ​a carefully optimized combination of stiffness – necessary to protect the fragile dome from unwanted damage – and openness.​The new design is more open than ever, which enhances both ​resolution and spaciousness. The orientation of the structure is specific and engineered to ensure the best results.​We had over 25 iterations in the development process of this new design!   New Bass Unit for 801 D4 Signature and New Mid/Bass for 805 D4 SignatureIn 801 D4 Signature, 10-inch low-frequency unit has been ​re-engineered to deliver even lower distortion.​We take the same approach with the mid/bass drive unit on 805 D4 Signature, which also features an upgraded pole on the magnet plus ​a larger vent hole for improved current distortion.     Upgraded CrossoversBoth 801 Signature and 805 Signature feature upgraded bypass capacitors. These are also doubled-up in quantity across the boards. The result is an even cleaner sound.     Upgrades from standard model include: Top-plate is rigidly coupled with additional fixings, new tweeter grille mesh, new bass/midrange unit with upgraded pole on the magnet plus a larger vent hole for improved circulation, upgraded crossovers
