Applications

- These models have been designed for Bass-Midrange applications in the field of Sound Reinforcement
- They can be used in two-way and three-way systems of 300W AES when high sounding quality and high efficiency are needed
- Maximum recommended X-over freq. is 2.0kHz, Optimum Bass-Reflex loading is situated between 40L and 50L tuned from 48Hz to 52Hz

Design Concept
Deflection Controlled Diaphram
- 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
- It is this leading edge technology which offers substantial sonic advantages
- Those advantages include sound coherency, fast transients, stable sound imaging, high sensitivity, wide frequency range and reduced directivity pattern

Vented Compact Magnet System
- Carefully optimized to obtain maximum transducing efficiency while avoiding unlinear behaviour such as coil inductance variation with position, flux modulation, harmonic distortion, rest position offset, air compression and off-axis voice-coil pushing
- Design incorporates a T-shaped and vented pole piece as well as a flux stabilizing ring
- It also takes into consideration demagnetization and cold temperatures

Intercooler System
- Entirely integrated into the loudspeaker itself, the Intercooler System extracts the heat produced by the Joule effect in the voice-coil
- It does so via 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
