12HPL64 specifications

B&C Speakers has long been synonymous with high-quality professional audio systems, and the 12HPL64 continues this tradition with its exceptional design and performance capabilities. This 12-inch low-frequency loudspeaker is engineered to deliver outstanding sound quality, making it an ideal choice for a variety of applications, including live sound reinforcement, studio monitoring, and high-fidelity audio reproduction.

One of the standout features of the 12HPL64 is its impressive power handling capacity. With a continuous power rating of 400 watts and a peak power handling of 1600 watts, this speaker is designed to withstand the rigors of high-output applications. This durability is complemented by its lightweight construction, providing an excellent balance between portability and performance.

The 12HPL64 employs a unique cone mix of materials that ensures optimal stiffness while minimizing weight. This cone design contributes to its exceptional low-frequency response and helps to reproduce deep and impactful bass without distortion. The speaker's frequency response ranges from 40 Hz to 4 kHz, making it versatile enough for a range of sound reinforcement tasks.

Moreover, the 12HPL64 utilizes a robust voice coil, which enhances thermal stability and improves overall efficiency. This feature allows the speaker to maintain consistent performance even under rigorous conditions, making it ideal for extended use in live venues or professional installations. Additionally, its 4-inch voice coil helps to dissipate heat effectively, reducing the risk of damage during high-energy performances.

The speaker is equipped with an advanced suspension system that enhances its linearity and dynamic response. The linear suspension ensures that the cone remains stable under varying loads, resulting in reduced distortion and improved sound clarity. This feature is particularly beneficial in applications where accurate sound reproduction is critical.

Another notable characteristic of the 12HPL64 is its high-quality neodymium magnet. This magnet not only contributes to the speaker's lightweight design but also plays a vital role in improving magnetic efficiency, resulting in higher sensitivity and lower distortion levels.

In conclusion, the B&C Speakers 12HPL64 stands out due to its exceptional power handling, lightweight construction, and superior sound quality. Its cutting-edge technologies make it a reliable choice for professionals seeking a robust and high-performance low-frequency loudspeaker, capable of delivering captivating audio experiences in any setting.
