Description
The Beyma AST22 is a high-output 4-inch tweeter designed to add upper-frequency clarity and projection to mobile, motorcycle, powersports and professional-style audio systems. Its aluminum diaphragm and high sensitivity make it suitable for open-air and high-noise environments when paired with compatible midrange or midbass drivers.
The AST22 is sold individually and must be protected with a high-pass crossover frequency and slope appropriate to the system.
