The most significant – and presumably most expensive – upgrade for this generation is to be found in the tweeter. Diamond or carbon domes, as used higher up B&W’s range, are not tenable in this price category, so instead the manufacturer has developed a new titanium dome tweeter. A two-part design, this features a 25µm-thick main dome framed by a marginally chunkier (30µm) titanium ring, and fires through a new mesh grille derived from the 800 D4 series’ tweeter assembly. For this generation, the positioning of the tweeter is also closer to the midrange below (their trim rings ‘overlap’) to improve driver integration.

The titanium dome is mounted into an elongated tube that’s hidden inside the cabinet. The principle behind this design is nothing new for B&W – albeit more apparent with its ‘Tweeter-on-Top’ models – and is intended to progressively attenuate the rear output of the tweeter, minimising rear reflections while also isolating the driver from pressure variations within the main cabinet.
