Eminence PXB2:3K5 2-Way Speaker Crossover Board 3,500 Hz
Does it hurt to "overbuild on a cross over. If I have a 250 w 2-way cab, is there any drawbacks to using a 400 w crossover
There is nothing wrong with doing this, this simply means the crossover can handle more power than the other components in the system.

I have: Eminence ASD1001 1" HF Titanium Horn Driver Eminence Delta-12A 12" Driver Is this the right crossover for this pair? The ASD1001 recommends using a 2.5k crossover, but the RMS for that crossover is a little lower than I would like.
Yes this crossover will work for that combination.

crossover freq using a 4 ohm woofer
If I use a 4 ohm woofer with this crossover, will the crossover point be cut in half to approx. 1800hz? I am guessing that the slope will remain the same. Just the crossover point will change.
The crossover point will actually go up but not quite double due to the fact that this is a second order crossover. The slope and high pass crossover will not change.

Can this crossover be used with the eminence Beta-8CX coax driver with an added GRS PZ1188 Piezo tweeter.
Yes although you will need to install an 8 ohm resistor in parallel with the piezo tweeter in order for the crossover to function properly.

Is it necessarry to have a separate crossover for each speaker?
I have an acoustic guitar amp with 4 ea 8-ohm speakers; all four blown. Got the eminence CX2008 speakers, and just found out I need to get the tweeters separately, and need a crossover or crossovers. How many speakers will each crossover handle?
The crossover will handle any number of speakers if the impedance is correct and power is not excessive. If you series-parallel wire your speakers to 8 ohms you solve the first question. This crossover will handle 400 watts RMS. How much power does your amp deliver? I haven't seen an acoustic guitar rig cranking out 500 watts, so unless you are the exception, this works in theory. Speaking of theory, one beefy tweeter instead of one in each speaker might sound clearer without costing more... and that would also work with this crossover.

Do I need to reverse the polarity of the horn with respect to the woofer?
I've read that there is a phase reversal through a crossover. That is, the horn signal may be 180 degrees out of phase with the woofer signal. Is that true? Should I reverse the polarity of the horn wires? The cabinet sounds great as is. I'm not sure my ear would hear a phase problem or not.
This product is designed with phase taken into account, so one should not "need" to reverse the polarity of the high frequency driver.
