B&W 800 series Sphere/Tube how it works


Whether it’s raw rock, powerful arias or any of the choral repertoire, voices are central to musical communication and conveying all the emotion requires the very best midrange rendition – the finest driver operating in an ideal enclosure. Taking the simple tube concept of the original 4-way Nautilus™ a stage further, we perfected the Nautilus™ ’head’ to allow a single driver to cover the whole of the critical mid band in one seamless sweep. Crafted from inert Marlan® composite, the internal cavity – a sphere closely coupled to a short tube - absorbs most of the sound from the back of the driver, with the fibre filling mopping up the last vestiges. On the outside, the glossy teardrop shape smoothly disperses the sound around the speaker creating a solid, three-dimensional image.
