QUANTUM 757 WHITE

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

The Quantum 757 is the flagship in the Quantum 750 series. Besides the extremely low-resonance 45 mm case front on a corpus with multiple stiffening, 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 757 is available in a black, white and black-mocca finish. Two bass loudspeakers and one bass/mid-range loudspeaker with a diameter of 170 mm in conjunction with a ceramic-aluminium cone in a high-strength die-cast basket are responsible for highly precise sound and clean transitions to the powerful "F-Max" fabric dome tweeter with dual-compound cone. The offset high-gloss base is responsible for a stable stand and a perfect look.
