Quantum 675

Floor-standing loudspeaker, 2.5-way bass reflex with double bass


The Quantum 675 is the smaller of two floor-standing loudspeakers in the Quantum 670 series, a further development of Magnat´s Quantum 650 series, which was highly praised in many test reviews. The elegantly rounded MDF case with its elaborate struts and varnished 25 mm acoustic baffle constitute the strong foundation for high-strength aluminium-ceramic cones and the lightweight dome made of synthetic silk with redesigned horn flare.




The Quantum 675 is available with a black and mocha-coloured corpus, the baffle on both versions possesses a black piano-lacquer finish. One bass and one bass/mid-range loudspeaker with a diameter of 170 mm in conjunction with Magnat´s proven ceramic-aluminium sandwich cone in streamlined baskets made from carbon-fibre-reinforced ABS are responsible for highly precise sound and harmonious transitions to the dynamic second-generation "HRH" silk dome.
