2-way bass-reflex centre loudspeaker

The centre speaker in the Quantum 720 range comes in a classic dual bass format and is equipped with two FE Dynamics 130 mm subwoofers. The Klippel-optimised chassis with a ceramic-aluminium membrane have a high load capacity and deliver precise, structured mid-tones. The upper frequency range uses the HRH tweeter with a 30 mm fabric membrane, special damping and ferrofluid cooling as well as a wide bead and a Harmonic Radiation Horn made of aluminium. The MDF enclosure, which is rounded at the sides and rear, is equipped with a low-resonance 25 mm baffle in a silk-matt lacquer finish. The fabric front cover is secured magnetically.
