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.

High-quality chassis components

The FE Dynamics subwoofers and woofers with a size of 130mm and 170mm respectively are made of a ceramic-aluminium membrane. These harmonize perfectly with the 30 mm fabric tweeters of the range and deliver a very dynamic and transparent, spatial soundscape.

Strong and stable

An elaborately braced MDF enclosure and sturdy traverses with adjustable conical spikes form the foundation for a loudspeaker with outstanding sound qualities.

Acoustic giant

A total of four loudspeaker chassis are located in the enclosure, which is rounded at the sides and to the rear. The elaborate design with the 25 mm baffle and the traverses reliably prevents undesirable resonances.
