Shelf loudspeaker, 2-way bass reflex

The Quantum 803 is the Quantum 800 series´ shelf loudspeaker and besides the refined sound of an absolutely top-of-the-range loudspeaker that possesses a lavish range of features and that has been built using the latest methods, the Quantum 803 comes with the perfect high-gloss varnish finish and the clear language of shape that is expected of a piece of furniture of the highest quality.

The Quantum 803 is available either in a black or white high-gloss varnish or a deep-brown rosewood finish. One bass/mid-range loudspeaker with a diameter of 170 mm in conjunction with a ceramic-aluminium cone is responsible for highly precise sound and clean transition to the high resolution “F-Max Signature” fabric dome tweeter. A particularly slender case is responsible for the Quantum 800 series´ extremely elegant look.
