Default Nautilus

The B&W Nautilus has been greeted worldwide as an outstanding loudspeaker which will shape the direction of the audio industry well into the new millennium. Already sought after by cognoscenti, it has been unashamedly designed with the serious audiophile in mind, not only because of its size and shape but also because of its active design - the crossover network is positioned between the pre and power amplifiers. This means that a full Nautilus system needs one stereo pre-amplifier and eight monobloc or four stereo power amplifiers per pair (amplifiers of 100 watts upwards are recommended, with 500 watts being the optimum for the low frequency drive unit).
