I need to deliver about 40 watts to a piezo tweeter at 30 khz. The tweeter is an CTS ksn1016A and is rated at 45 watts and is good for 40 khz. The amp is an LM7828 rated at 40 watts into 8 ohms. The problem is the tweeter has an capacitive reactance of 84 ohms at 30khz. The impedance mismatch is so bad I`m only geting a few hundred miliwatts into the tweeter.https://www.electro-tech-online.com/custompdfs/2004/02/LM2876.pdf.
