6.5” Bass Midrange Drivers

Ultimate Sounding Quality

APPLICATIONS

These 6.5”ultimate sounding quality Bass-Midrange drivers have been designed to match advanced studio monitoring requirements for proximity monitoring.

The exceptional sound accuracy of these units results from

a careful design using A/B listening tests to select technological solutions, which authorizes their use up to 2.5kHz without any compromise, and up to 4.0kHz with full preservation of dynamic behavior (Compromise is on directivity pattern only).

Optimum Bass-Reflex loading is situated between 12L and 16L tuned from 45Hz to 40Hz.

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.

SOFT EXCURSION LIMITING. The SOFT EXCURSION LIMITING mechanism is a special S-profile design of the rubber surround avoiding voice-coil bottoming which destroys driver functionality instantaneously.

The cone excursion is progressively limited to +/- 8mm, introducing a soft clipping which totally protects loudspeakers from over-excursion damage.

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.

PHL Audio specifications 1220 8 Ω, 1230 16 Ω, Bass Midrange Drivers Ultimate Sounding Quality

1220, 1230 specifications

PHL Audio is renowned for its commitment to high-quality audio reproduction, and their PHL Audio 1220 and 1230 models stand out as exceptional tools for both professional audio engineers and enthusiasts. These two speakers are designed with precision and innovation in mind, providing an unparalleled listening experience across various applications, including live sound, studio monitoring, and installations.

The PHL Audio 1220 features a 12-inch low-frequency driver designed to deliver robust bass performance while maintaining clarity across the audio spectrum. Its unique cone design and advanced suspension system ensure reduced distortion at high sound levels, making it ideal for live performances where sound pressure levels can be considerable. The driver is coupled with a 1.4-inch high-frequency compression driver, which utilizes a titanium diaphragm to produce smooth, detailed highs with excellent transient response.

On the other hand, the PHL Audio 1230 is an upgrade that incorporates a 15-inch low-frequency driver for those who demand even more bass response. Like its sister model, it features a meticulously engineered cone structure that enhances both efficiency and linearity. The high-frequency driver is also upgraded, providing a broader listening area without sacrificing clarity. Both models utilize a new waveguide technology, ensuring wide dispersion of sound and providing balanced audio across the stage or room.

Both the 1220 and 1230 come with user-friendly connections and robust construction, ensuring durability and reliability even in challenging environments. Their lightweight design, combined with a rugged cabinet made from high-quality materials, makes them easy to transport and set up.

Another significant feature is the versatility these speakers offer. They can be used in various configurations, including as stand-alone units, or as part of a larger sound system, making them suitable for multiple applications ranging from concerts to corporate events.

In terms of sound characteristics, users can expect a well-balanced frequency response with an emphasis on sonic clarity. The incorporation of advanced technologies allows both models to perform exceptionally well, ensuring that every note is articulated with precision.

In conclusion, the PHL Audio 1220 and 1230 deliver outstanding audio performance, advanced technologies, and versatile applications, making them must-haves for anyone serious about sound quality.
