Optimised components ensure excellent performance
An impressive bass is just one of the qualities of the 25 cm subwoofer with the Heco kraft paper diaphragm. Thanks to development using Klippel laser measurement technology, the chassis drive features optimum low distortion, delivering the highest sound precision right into the mid-tone ranges. To ensure this is also maintained in the deep bass range, two flow-optimised, rounded reflex tubes on each side of the bottom of the enclosure provide for optimum acoustic coupling to the room. At 2.350 Hz, a 28 mm silk-compound cone with a particularly wide surround takes over. Thanks to a powerful double magnet system and efficiency-enhancing wave-control horn made of aluminium, it provides for excellent dynamics and is therefore the ideal partner for the particularly dynamic subwoofer. The result is a finely balanced soundscape of the highest precision. The crisp bass, the extremely clear and direct mid-tone range and the dynamically fine treble range are accompanied by outstanding dynamic capabilities. Efficiency, dynamics and tonal purity at this level can otherwise only be achieved with horn loudspeakers – however, the HECO Direkt delivers these qualities without the often aggressive aftertaste of the horns. Its particularly high efficiency and the impedance characteristics linearised via the impedance control circuit also make it suitable for tube and transistor amplifiers over 10 watts per channel.
Top technology and timeless design
The sloping flat enclosure specially designed for the HECO Direkt not only provides for visual elegance, it also offers tangible acoustic advantages. The extra-wide baffle and the backward tilt optimise the dispersion characteristics and the acoustic phase of the chassis combination. The three-point mounting on sleek all-metal feet ensures optimum weight distribution in physical terms. Visually, the influence of iconic guitars from rock history on the Direkt is unmistakable. The name of the loudspeaker says it all – it gets "Direkt"-ly to the point!
