One final question relative to this crossover. If I design the crossover to filter an 8-0hm speaker load, and then subsequently wire that speaker system to another 8-ohm speaker system giving a load of 4-ohms, is my crossover still accurate?

I don't understand if the crossover is affected my total resistance or only by the resistance after the crossover? Sorry for the dumb question!

and thanks again for your assistance DYohn! Much appreciated!

If you use passive crossovers then yes any downstream impedance change will affect the X-over point (and the slope to some degree.) If a system is designed for an 8-ohm load and you change it to a 4-ohm load, for example, the crossover point will be doubled. I highly recommend using active crossovers for a pro-sound setup as it gives you far more flexibility and the setup is not affected by downstream changes.
