With a first order crossover is usually ment there is one filtering component for a driver in the crossover , for example 1 cap as a tweeter filter or 1 coil for a bass driver .
This usually results in gradually sloping roll offf for the units , with second or 3 rd order crossovers you have steeper declines at the crossover frequencies , besides that you have off course series filters (constant voltage ) as its known also (if i am correct) and parallel filters
In my expirience , the more filtering components you add the more phase problems could arise , but others might differ .
You need filtering components its a designers trade off
look forward seeing the pics mike , should be quite a different sound expirience
