If you put a 20 ohm resistor across a piezoeletric tweeter, then the 20 ohm resistor becomes the dominant portion of the load impedance. The impedance of the tweeter is so high (except at the highest frequencies) that the load impedance is 20 ohms, and the impedance of the tweeter becomes almost insignificant. You could then use a standard crossover circuit that expected a 20 ohm resistive load. Check the collection of posts below for more information about implementing piezoelectric tweeters.
