[QUOTE="David Morison, post: 214194, member: 2076"] One thing to be careful of - if the original HF drivers were piezo's as you say, the crossover for them may well be much more basic than needed for a proper compression driver. This is because piezo's have a rising impedance as frequency decreases, so they naturally draw less power down low, making them more tolerant of very basic crossover circuits. Real compression drivers do not behave in the same way so often need more comprehensive crossovers. If you can, draw out the circuit from your crossovers and post it here, or at least post pics of it (both front & back so we can see what's connected where) before putting any power through your new compression drivers.
