Centre loudspeaker, 2-way bass reflex, double bass

The geometry of the acoustic baffle and crossover in the two-way Quantum Center 67 centre loudspeaker have been adapted to each other to optimise this speaker to achieve great clarity of speech in particular.

Centre loudspeaker, 2-way bass reflex, double bass

The Quantum Center 67 is the centre loudspeaker that goes with the Quantum 670 Series – both the geometry of the acoustic baffle and coordination of the crossover have been specially adapted to each other to produce great clarity of speech. 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 Center 67 is available with a black and mocha-coloured corpus, the baffle on both versions possesses a black piano-lacquer finish. Two bass/mid-range loudspeakers 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 a highly precise sound and harmonious transitions to the dynamic second-generation "HRH" silk dome.
