12 PZ 32 specifications

B&C Speakers has long been recognized as a leader in audio technology, and the 12 PZ 32 is a prime example of their commitment to excellence in speaker design. This high-performance 12-inch loudspeaker is tailored for professional audio applications, delivering remarkable sound quality and efficiency.

One of the standout features of the 12 PZ 32 is its exceptional sensitivity, rated at 98 dB 1W/1m. This high sensitivity allows the speaker to produce louder sound levels with less power, making it an excellent choice for both portable and installed systems. Whether it’s for live sound reinforcement, stage monitoring, or fixed installations, the 12 PZ 32 is capable of delivering robust performance without requiring excessive amplification.

The speaker is built around a lightweight yet durable die-cast aluminum frame that enhances stability and reduces unwanted vibrations. This design not only improves the overall structural integrity of the speaker but also contributes to clearer audio reproduction. The 12 PZ 32 features a 2.5-inch voice coil, allowing it to handle high power levels with ease. With a power rating of 300 watts RMS and a peak handling capacity of 1200 watts, this speaker can withstand the rigors of demanding audio environments.

Moreover, the transducer design employs a state-of-the-art cone made from a specially formulated pulp blend. This cone material not only optimizes the frequency response but also allows for smooth transitions between low, mid, and high frequencies. The result is a natural, balanced sound that reproduces vocals and instruments with remarkable accuracy.

The 12 PZ 32 is equipped with a powerful neodymium magnet, which significantly reduces weight while providing excellent magnetic performance. This contributes to the speaker’s overall efficiency and helps maintain clarity at higher volumes. Additionally, the design minimizes power compression, ensuring consistent output even during prolonged use.

Another technological highlight of the B&C Speakers 12 PZ 32 is its advanced suspension system, which enhances linearity and responsiveness. This careful engineering ensures that the speaker performs reliably across a broad frequency range, from deep bass to crisp treble. It also showcases minimal distortion, making it ideal for critical listening applications.

In summary, the B&C Speakers 12 PZ 32 combines high sensitivity, impressive power handling, and advanced materials to deliver outstanding audio performance. Its robust construction and thoughtful design make it a versatile option for any professional audio setup, whether for live events or permanent installations. With the 12 PZ 32, audio professionals can trust they are utilizing a product engineered for excellence and reliability.
