PHL 5010/B38
15" Bass Midrange Driver, Ultimate Sounding Quality
US $450.84

- This model is intended to be used in cases where neither ultimate transcription sound nor full outdoor environmental withstanding are requested
- The main use is in the field of Studio Monitoring
- Its linear pressure response up to 1kHz, together with the smooth upper roll-off 
are ideal for this application
- Recommended acoustical load is in a Reflex enclosure of 90L to 120L tuned from 40Hz to 43Hz, while usable freq. range is possible up to 600Hz depending only on the directivity compromise you agree on

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

- Power handling capacity - 500W ABS
- Reference Efficiency (1W @ 1m) - 97 dB SPL
- SPL max (continuous) - 120 dB SPL
- Usable frequency range - 35-2000 Hz
- Environmental withstanding - Outdoor
