    Motorola made that piezo tweeter many years ago and other companies copy it. I have the horrible frequency response curve. The curve is heavily smoothed and is actually much worse.

    The output is an average of 94dB/1W at a distance of 1m. It is only 88dB at 2m, 82dB at 4m and 76dB at 8m for 1W.
