Applications

- These models, while derived from SP5050 are optimized for very high SPL two or three way sound reinforcement systems of high sounding quality
- The object of PHL's research was the development of a lighter cone assembly to optimize sensitivity without decreasing toughness and life duration
- The challenge is successful with their special treatment of both sides of the cone which allows it to withstand tremendous SPL at very low harmonic distortion levels
- Thus, these models can be used far into the midrange frequencies (over 1.2 kHz if needed) without sacrificing sound quality
- Optimum acoustical load is Reflex enclosure from 45L to 70L tuned around 46 Hz

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
