(This was previously posted in TechTalk, but I added it here too - Jeff)
I have written and article on how to use OmniMic (or other measurement system) and my Passive Crossover Designer Excel tool to determine very accurately the relative acoustic offset between a woofer and tweeter's acoustic center for accurate crossover design simulation.
Finding this value is not difficult if these steps are followed, and once found will allow for very accurate crossover design simulation using my Passive Crossover Designer. Without knowing this value phase relationships will not be accurate, and as a consequence, the accuracy of the modeled response will be reduced as well.
As you will see, perfect measurements are not necessary. To make this point my example was done in my family room intentionally to show that you can do this the same way.......
