Centre loudspeaker, 2-way bass reflex, double bass

The Quantum Center 73 is the centre loudspeaker that goes with the Quantum 750 series. Besides the extremely low-resonance 40 mm case front on a stiffened corpus, it offers a clear and modern language of shape that is available in perfect high-gloss or silk-matt varnish finishes. The latest-generation computer-optimised loudspeaker chassis deliver an uncompromisingly clean and dynamic sound.

The Quantum Center 73 is available in a black, white and black-mocca finish. Two bass/mid-range loudspeakers with a diameter of 130 mm in conjunction with a ceramic-aluminium cone in a high-strength die-cast basket are responsible for highest sound precision and clean transitions to the powerful "F-Max" fabric dome with dual-compound cone. The double configuration in the bass and mid-range produces excellent dynamism for home-cinema applications.
