An audio power amplifier that can drive a 4 ohm load can drive 15 paralleled piezo tweeters up to 20kHz.
Piezo tweeters were used 50 years ago. I am surprized that they are still being sold as replacements. I found them at Parts Express at a very low price but with absolutely no audio spec's. Reviews say, "Not for hifi".
