Quantum 727

3-way bass-reflex loudspeaker with dual bass system

As the top model of the Quantum 720 range, the Quantum 727 is equipped with a total of four loudspeaker chassis. Two of the three 170 mm FE Dynamics woofers are responsible solely for the basses and, combined with the generously dimensioned enclosure volume, deliver a voluminous bass foundation, with the third one contributing precise voice reproduction. The drivers are Klippel-optimised and fitted with a ceramic-aluminium membrane. The treble range delivers fine resolution through a 30 mm HRH tweeter with fabric membrane, special damping and ferrofluid cooling. The components are accommodated in an elaborately braced MDF enclosure that is rounded at the sides and rear and has a particularly low-resonance design. The fabric cover on the silk-matt lacquered baffle is secured magnetically.
