I replaced the piezos on mine with some JVC planars. Terminated the crossover section for the piezos with an 8 Ohm resistor to reduce possible interactions with the rest of the crossover, and crossed the 4 Ohm JVCs in around 12.5kHz with just a series capacitor and a fixed resistive L-pad, cutting output by about 4.5dB to match the dome tweeter. HUGE improvement in treble quality.
Some owners have removed both the piezo and its highpass section entirely, and replaced the original dome tweeter with a modern ScanSpeak unit that plays flat past 20kHz and has similar impedance/sensitivity specs to the original. Forget which ScanSpeak model.
Piezo tweets aren't ENTIRELY useless. You can hook 'em up to a small amp, and run a frequency generator set around 22kHz into the amp. DIY gopher chaser and neighborhood dog tormentor.
