Description
B&W 804 D4 Signature : Bookshelf Speaker
he 805 D4 Signature stand-mount loudspeaker features optimised technologies, including that all-important Diamond Dome tweeter and Solid Body Tweeter-on-Top, an all-new tweeter grille, and upgraded crossover.
Diamond Dome tweeter
One of our most significant accomplishments over the past two decades, the ultra-stiff, supremely accurate Diamond Dome tweeter is the perfect combination of low mass, exceptional stiffness, and outstanding accuracy. Fifteen years after we introduced it, we haven’t found a better tweeter dome technology.
All-new tweeter grille
Our Solid Body Tweeter-on-Top housing features an elongated form with a longer tube-loading system and an all-new design of tweeter grille, producing an even more free and open sound with high frequencies.
Our 805 D4 Signature uses upgraded 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.
