12 PH 32 specifications

B&C Speakers 12 PH 32 is a high-performance transducer that is specifically designed for professional audio applications. Renowned for its ability to deliver exceptional sound quality, this 12-inch driver combines innovative engineering with robust construction, making it ideal for both live sound and installed audio systems.

One of the primary features of the 12 PH 32 is its neodymium magnet structure. This lightweight yet powerful magnet significantly enhances the speaker's efficiency, allowing it to produce a high-output volume with less power. This characteristic makes the 12 PH 32 an excellent choice for applications requiring portable solutions, as the reduced weight aids in ease of transport without compromising sound clarity.

Another noteworthy aspect of the 12 PH 32 is its frequency response. The speaker covers a frequency range from 40 Hz to 4 kHz, ensuring deep bass performance while maintaining clear midrange reproduction. This wide frequency response allows the driver to be used in a range of applications, including subwoofer configurations, full-range cabinets, and stage monitors.

The diaphragm of the 12 PH 32 is constructed from high-quality materials, contributing to its durability and sound reproduction fidelity. The use of a treated cellulose pulp cone provides a natural sound quality, while the lightweight suspension system allows for greater linearity and reduced distortion at higher volumes. Additionally, the driver features a robust voice coil that can handle high power levels, making it suitable for demanding audio environments.

Thermal management is another critical technology integrated into the 12 PH 32 design. The speaker is equipped with an innovative heat management system that dissipates heat effectively, ensuring consistent performance even during extended use. This feature is particularly valuable in professional settings where prolonged operation is common.

Furthermore, the design includes a specially shaped throat and optimized phase plug, which enhance the speaker’s directivity and transient response. This ensures that sound is projected evenly across the listening area, improving overall audio quality during performances or installations.

In summary, the B&C Speakers 12 PH 32 is a premium 12-inch driver that excels in professional audio environments. With its neodymium magnet, wide frequency response, high-quality diaphragm, and superior thermal management, it delivers outstanding performance across various applications. This speaker stands out as a powerful and reliable solution for audio engineers, musicians, and sound reinforcement professionals alike, elevating audio experiences to new heights.
