The tweeter's frequency response is rated from 2.2kHz to 20kHz, making it well-suited for reproducing the full range of human hearing. Its sensitivity is listed at 86dB, making it a versatile option for various system designs and power levels. The impedance is 8 ohms, enabling seamless integration with a wide range of amplifiers and audio systems.
The Audax HD12x9D25A Polydax Tweeter is designed with a rugged, high-temperature voice coil former and a sturdy mounting system to ensure reliable performance and durability. The tweeter can be mounted using the included 1/2-inch (M13) threaded inserts or using the optional keyed clamp mount. Its compact size of 3.5 inches (88.9mm) in diameter and 1.2 inches (30.5mm) in depth makes it a perfect fit for various applications, including bookshelf speakers, monitor speakers, and studio monitors.
