Eminence PXB2:3K5 2-Way Speaker Crossover Board 3,500 Hz
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?
This crossover is a two way crossover so each crossover can take two speakers. One tweeter and then a mid or subwoofer.

Is this designed for an 8ohm woofer and an 8ohm tweeter? Would the total load to the crossover appear to the amplifier as 16ohms, 8ohms, or 4ohms?
Respectfully, was considering replacing one of four 10" 16ohm bass drivers from my custom 4ohm bass cabinet with this coaxial system and wanted to balance the load near 4ohms again... ideas? Warnings? THREATS?
Its for 8ohm drivers; and would be 8ohm output.

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.

Which crossover should I use?
My tweeter is the Eminence Apt 150 and the woofer is the Alpha 15 should I use the PXP2:3K5 crossover board 3,500 Hz or the Eminence PXB:3K5 High Pass crossover board.And Why one over the other?-Jeff
With a 2-way design, the standard approach would be to employ a 2-way crossover, rather than a high pass. The high pass filter will protect your tweeter, but will not have any effect on the woofer.

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.

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.
