Bowers and Wilkins Nautilus


The Nautilus is a Bowers & Wilkins concept loudspeaker first released in 1993. It uses tapering tubes filled with absorbent wadding to reduce resonances to an insignificant minimum. Nautilus Tapering Tubes are fitted to nearly all Bowers & Wilkins speakers, even when they’re not visible to the eye. Tapering the tube enables you to make it shorter for the same level of absorption; it acts like a horn in reverse – reducing the sound level instead of increasing it.

The limit of this type of loading is reached when the wavelength gets small enough to be comparable with the diameter of the tube. To maintain the effectiveness of tube loading, you must restrict the bandwidth of each driver. This is one reason why the Nautilus loudspeaker is divided into a 4-way system. A more complex type of loading is required to cover a wider bandwidth and the sphere/tube enclosure was developed for the Nautilus 800 Series.
