Quantum 807

Floor-standing loudspeaker, 3-way bass reflex with double bass

The Quantum 807 is the flagship in the elegant Quantum 800 series 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 807 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 807 is available either in a black or white high-gloss varnish or a deep-brown rosewood finish. Two bass loudspeakers and one mid-range loudspeaker each with diameters of 170 mm in conjunction with a ceramic-aluminium cone are responsible for highly precise sound and clean transitions to the high resolution “F-Max Signature” fabric dome tweeter. A particularly slender case is responsible for the Quantum 800 series´ extremely elegant look.
