Key Design & Engineering Features
Extruded Aluminum Enclosure: The cabinet is formed from a single, rigid, curved piece of extruded aluminum, which drastically reduces internal standing waves and cabinet coloration. 
Nautilus Tube-Loaded Tweeter: Uniquely mounted externally on top of the cabinet, the 25 mm (1 in) aluminum dome tweeter uses B&W's iconic Nautilus tapered tube technology to absorb unwanted rear sound energy, resulting in open and detailed highs. 
Woven Kevlar Bass/Midrange Driver: Features a 130 mm (5 in) yellow Kevlar cone paired with a front-firing Flowport to smooth out airflow and deliver clean, punchy mid-bass.
