APPLICATIONS

These models are the ”long excursion” versions of types SP1500/1510. They are dedicated to being used when applications require low-midrange extension capability together with high SPL.

Their particular design ensures that they perform without any compromise in sound quality, making these models optimum for sound reinforcement systems as well as studio monitoring.

Their preferred frequency domain starts from 400Hz (single unit) or 300Hz (dual driver) in direct radiation, while 200Hz is possible when horn is mounted.

DESIGN CONCEPT

PROGRESSIVE WAVE DIAPHRAGM optimized for low-midrange extended frequency domain.

The M17/E17 Series design is based on the PROGRESSIVE WAVE DIAPHRAGM mechanical behavior of the radiating area.

In this principle, the membrane is considered as a mechanical transmission line which should receive a constant given velocity together with critical damping properties to work properly.

This leading edge technology offers substantial sonic advantages. Among them : very low mechanical energy storage in the cone (avoiding standing waves) which ensures coherent sound, fast transients, stable sound imaging, high sensitivity, wide frequency range and very-low 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.

1670, 1660 specifications

PHL Audio has long been at the forefront of the professional audio industry, renowned for its dedication to developing loudspeakers that deliver exceptional sound quality. Among their esteemed offerings are the PHL Audio 1660 and 1670 models, which embody the brand's commitment to precision engineering and innovative design.

The PHL Audio 1660 is designed for versatility, suitable for a range of applications including live sound reinforcement and fixed installations. One of its most notable features is the 15-inch cone woofer, which delivers deep bass response and high power handling. The high-efficiency design allows for extended output levels without distortion, making it ideal for larger venues. Accompanying the woofer is a coaxial high-frequency driver that ensures smooth tonal transitions across the frequency spectrum, ensuring that vocals and instruments remain clear and articulate even at high volume levels.

Transitioning to the PHL Audio 1670, this model offers an even broader frequency response, catering to audiophiles and professionals seeking unmatched audio fidelity. The 1670 is equipped with a meticulously engineered 10-inch woofer and a 1.4-inch compression driver, allowing it to reproduce frequencies from the deepest lows to crisp high notes with ease. This robust design enables it to handle peak power requirements without compromising on sound quality.

Both models incorporate advanced technologies, such as high-grade component materials that enhance durability and performance. The cabinet design is optimized for reduced resonance and improved sound projection, which helps maintain clarity even in challenging acoustic environments.

One characteristic that stands out in both models is their modular design, which allows for easy integration into various sound systems. The quick-connect terminals and adjustable mounting options make deployment straightforward for sound engineers and technicians. Additionally, both speakers feature an elegant, professional finish, making them visually appealing for any setting.

In conclusion, the PHL Audio 1660 and 1670 loudspeakers exemplify the brand's dedication to quality and innovation in audio technology. With their impressive specifications and advanced features, these models cater to the demands of modern audio professionals, making them an excellent choice for both live performances and permanent installations. Whether used in concert halls or studio environments, the PHL Audio 1660 and 1670 promise to deliver a superior listening experience.
