High-quality piezo dome tweeter with a horn. This tweeter can be connected directly to the amplifier or to a crossover. The tweeter features a curved aluminum dome and does not have a cone membrane. Due to the aluminum dome, the sound pressure is not as high as with comparable other piezo tweeters. However, the speaker has a very wide dispersion angle and produces a very good, brilliant sound. Its particularly low-inertia aluminum dome with low moving mass allows for a very clean frequency response up to approximately 45,000 Hz. Therefore, this tweeter is also very suitable as an ultrasonic speaker for pest control.
