  • Nautilus is our touchstone: the result of a groundbreaking, five-year research and development mission to achieve, as near as possible, the perfect loudspeaker. The things we learnt by developing something so new, so different and so uncompromised have become our own rules for speaker design, and have informed every range weve created since. Thats down to advances in materials, crossover components and cabling, and to its pioneering use of tapering tubes in place of the conventional box cabinet.

    Nautilus

    B&W Catalogue.indd 6 17/5/07 12:27:6

  • What you hear from Nautilus is as different from ordinary speakers as what you see. Its shape and sound were created by straight and spiralling tapered tubes filled with absorbent wadding, designed to soak up wayward sound waves from the back of each drive unit and allow the sound from the front to reach you in as pure a state as youre ever likely to hear. In form and performance, Nautilus was and still is revolutionary.
