2.5-way bass reflex floor-standing loudspeaker

With an enclosure rounded at the sides and rear, silk-matt lacquered baffle, magnetically secured fabric cover – the Quantum 725 2.5-way bass-reflex loudspeaker boasts a very elegant visual appearance. And outstanding acoustic qualities: While a 30 mm HRH fabric tweeter with special damping and ferrofluid cooling provides for excellent transparency and resolution in the upper frequency ranges, two 170 mm diameter FE Dynamics drivers together take care of the bass ranges, with only the upper chassis responsible for the mid-tone range. Thanks to the ventilated voice coil and generous vents in the sturdy metal basket, the Klippel-optimised drivers with ceramic-aluminium membranes ensure high load capacity values.

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.
