Bowers & Wilkins BB 6C Backbox for In-Ceiling Speakers

The Bowers and Wilkins BB-6C Backbox

The back box is designed to increase the sound insulation to adjoining rooms, while also providing the fire safety barrier sometimes required by building regulations in order to prevent fires in the wall cavity from spreading into the room. 

When used in solid construction, the backbox will define an appropriate working volume for the speaker which may need to extend beyond the boundaries of the wall frame. 

Who are Bowers and Wilkins?

Bowers & Wilkins is a company that needs a very little introduction, having been constructing some of the world's most critically acclaimed loudspeaker and headphone models for half a decade. Starting at the entry-level 600 S2 series, through to the new 700 S2 series audiophile range, 800 Diamond series and flagship Nautilus model. These different series of loudspeakers have been praised as the superior listening experience in both two-channel hifi/music listening and in multi-channel home theatre applications, having claimed a vast multitude of awards in both categories. A Bowers speaker can be easily recognised by the signature yellow Kevlar midrange cone, which can be found with their 600 series with the latest 700 and 800 Series opting for a silver 'continuum' cone.
