About the Nautilus 804
The Bowers & Wilkins Nautilus 804 is a premium floorstanding loudspeaker that brings the advanced acoustic technology of the Nautilus series to a more living room-friendly size. It features a tall, slim cabinet with real wood veneer finishes, a freestanding tweeter on top for precise imaging, and a surround-less Kevlar® midrange driver for reduced distortion. The speaker employs tapered tubes to absorb rearward output of mid and high frequencies, and a Flowport™ bass reflex port for improved airflow and lower distortion. The Nautilus 804 is praised for its three-dimensional soundstage, revealing detail, and attractive aesthetics.
