The double passive radiator, found on Shape monitors in particular, offers an ingenious solution to the problem of proximity monitors: combining compactness, extended bass frequency response and easy positioning.
Indeed, where the venting system reaches its integration limit (need for a vent long enough to match its surface), the passive radiator is the ideal solution. However, asymmetrical oscillation (rocking mode) can occur as a function of frequency and sound level. To overcome this phenomenon, two half-roll surrounds, positioned in "mirror" mode, join the passive disk and the basket, ensuring total symmetry between excursion and incursion. Finally, the very low tuning frequency allows the monitors to be positioned very close to a sound barrier.

PRISM
The future of treble
PRISM technology is a major innovation in the mastery of high frequencies. By combining a multi-material substrate with an advanced micro-structuring process, it makes it possible to harness the full potential of each material and achieve stiffness superior to that of beryllium, while preserving a perfect balance between lightness, damping, and rigidity. The result of several years of research, patented and manufactured in France, PRISM sculpts membranes with unprecedented precision.
