Re: building keyboard speakers - driver question

Stick with the 2002. The off-axis response of the 12cx demands a crossover no higher than 2 kHz, and piezos don't sound good below 3.5 kHz or so. There's also the matter of sensitivity, and the piezo runs a good 10dB less than the 2002. Piezos work fine above 3.5 kHz, and have adequate sensitivity if you use enough of them, but this is one application where a piezo is the wrong choice.
The Delta 12a is a guitar driver, and shouldn't be used in a full range application.
