The Nautilus 803 speakers not only sound amazing, they are gorgeous to look at too.There are slight marks on the cabinet - see second photo. They are vented floorstanding speakers with 7" Woofers, 6" Mid and 1" Tweeter. Floor-standing design with a two in one cabinet construction, which reduces sound diffraction between the bass and midrange. Nautilus™ treble unit, Matrix™ cabinet and Flowport™ bass tube. The Nautilus 803 cabinet is made up of layers of ply. The graceful curves of the cabinet are skillfully moulded layer by layer which helps to eliminate the unwanted resonances caused by flexing of flat and square cabinet walls.
