12” Low Midrange Drivers

High Efficiency

High Sounding Quality

APPLICATIONS

These 12”high efficiency - high sounding quality low-midrange drivers have been designed to perform well in the 60Hz - 2500 Hz frequency domain where human hearing is so sensitive.

They can equip two-way or multi-way sound reinforcement systems of small to medium throw, when AES power handling does not exceed 250W.

Recovery with a 1”HF comp. chamber is simple, while recommended acoustical loading is Bass-Reflex from 40 to 50L depending on the low roll-off required, and tuned from 53Hz to 57Hz.

DESIGN CONCEPT

DEFLECTION CONTROLLED DIAPHRAGM optimized for dynamic damping. DEFLECTION CONTROLLED DIAPHRAGM technology consists in optimizing the shape and material of the diaphragm so that it works as a mechanical transmission line, to avoid breaking modes as well as mechanical threshold which destroy sound quality.

This leading edge technology offers substantial sonic advantages. Among them: sound coherency, fast transients, stable sound imaging, high sensitivity, wide frequency range and reduced directivity pattern.

VENTED COMPACT MAGNET SYSTEM. It has been carefully optimized to obtain maximum transducing efficiency while avoiding unlinear behavior such as coil inductance variation with position, flux modulation, harmonic distortion, rest position offset, air compression and off-axis voice-coil pushing.

Its design incorporates a T-shaped and vented pole piece, and a flux stabilization ring. It also takes into consideration demagnetization at cold temperatures.

INTERCOOLER SYSTEM (patented). Entirely integrated into the loudspeaker itself, the INTERCOOLER SYSTEM extracts the heat produced by Joule effect in the voice-coil by the means of an air flow directed through the heatsink rims of the basket by the motion of the dust-cap and the spider.

The gain brought about by this technology is over 20 % of extra power, so for example, a 3”coil according to this design has the same power handling capacity as a classical 4”one.
