250 AMX specifications

B&C Speakers is renowned for its commitment to producing high-quality audio equipment, and the 250 AMX model exemplifies this dedication. This mid-frequency horn driver is designed specifically for professional audio applications, providing robust performance coupled with advanced technology.

The 250 AMX features a powerful neodymium magnet structure, which enhances its efficiency and reduces its weight, making it a preferred choice for mobile sound systems as well as fixed installations. This model is capable of handling up to 250 watts of continuous power, making it suitable for high-pressure sound reinforcement scenarios.

One of the standout characteristics of the 250 AMX is its impressive frequency response. With a range that extends from 400 Hz to 4 kHz, it effectively reproduces critical mid-range frequencies essential for vocals and instruments. This attribute ensures clarity and precision, which are crucial for professional sound engineers and musicians alike.

The design of the 250 AMX includes a robust diaphragm made from a durable composite material. This not only contributes to the longevity of the driver but also ensures consistent performance over time. The diaphragm's lightweight construction allows for swift transient response, making it capable of handling complex dynamics without distortion.

Another key feature is the driver’s phase plug design, which minimizes distortion and enhances the dispersion of sound. This technology is particularly beneficial in large venues, where the even distribution of audio is necessary for maintaining clarity throughout the listening area. The phase plug also aids in reducing the effects of acoustical interference, ensuring a smoother response across its operational bandwidth.

Additionally, the 250 AMX is engineered for ease of installation. It features standard mounting options and is compatible with various horn designs, allowing for flexibility in deployment. Its rugged construction also makes it resilient to the rigors of touring, ensuring reliable performance in diverse environments.

In summary, the B&C Speakers 250 AMX is a powerful and versatile mid-frequency driver that excels in both mobile and fixed sound applications. With its advanced neodymium magnet structure, wide frequency response, durable diaphragm, and innovative phase plug design, it stands out as a leading choice among professionals seeking high-performance sound solutions. Its ability to deliver crystal-clear audio while maintaining ease of integration makes the 250 AMX an essential component in any serious audio setup.
