The toughest challenge for a high-end loudspeaker is to reproduce the lowest frequencies of larger instruments, such as an organ or double bass, with appropriate fidelity. Only very few speakers are at all able to reproduce the lowest register of a church organ and even then only the very best are able to make it sound as if it was coming from an organ pipe. To do credit to a double bass in all its glory without sounding fluffy or over-inflated or, even worse, giving up altogether, is the reserve of very few, outstanding loudspeaker constructions. The "Les Orgues" speaker series, in this case the GRAND ORGUE species, represent exactly that capability. With eight WS25E 8ohm woofers, optimised specifically as a free-air system, mounted in a folded, but open baffle, they are able to reproduce bass down to below 20 Hz in a most natural, unhurried and completely unexaggerated manner and with no sign of weakness. Since there is, in effect, no enclosure, the resonant frequency of the woofer is not increased, but in this case even decreased, which enables it to emanate clear, non-compressed extremely low frequencies. The precondition for this low-range bass imaging, which uses double-sided radiation, is, however, also to ensure the speakers are far enough away from the wall. One metre is sufficient, but for full power right to the bottom of the bass range, 2 - 3 metres is preferable.
