4070 8 Ω

12” Coaxial Bass Midrange Driver 1” Entry Horn ■ High Sounding Quality High Sound Pressure Level

APPLICATIONS

SP4070 is a 12”high SPL high sounding quality 1”exit coaxial bass-midrange driver derived from SP4040 basis and specially designed with coaxial horn to match the behavior of a 1”entry HF compression chamber.

A mounting plate with gasket and standard fastening is supplied for the fitting of the HF driver.

Its well balanced design between sensitivity / high power handling / bass- extension, combined with linear response and smooth upper

roll-off, make it ideal in Sound Reinforcement for ultra compact two way systems for proximity stage monitors, or side wedges of medium throw.

Recommended highest X-over is 2.5 kHz, while optimum acoustical load is Reflex type of 30L to maximum 40L tuned from 52Hz to 56 Hz.

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.

COMPACT MAGNET SYSTEM. Its design has been specially 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 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.

COAXIAL SYSTEM : PHL AUDIO COAXIAL SYSTEM concept is based on a horn which is formed by the cone profile and the pole piece extension of the LF driver.

The 1”horn entry is situated in the axis of the rear side of the magnet system.The front access to the LF driver voice-coil is protected against dust by an acoustically transparent dust-cap.

Coaxial drivers are always delivered with a compression driver standard mounting plate, screws and a 1”O ring sealing gasket.
