Re: Looksgto replace Basic Passive Crossover
If OAP designed the crossovers for the speakers, they will probably be better than anything you can buy "off the shelf".
The minor problems you have mentioned could require an additional half dozen parts in a passive crossover to fix.
Generic passive crossovers are usually designed considering the drivers as a resistive load, when used with real speakers, the acoustic crossover can be an octave (or more) off with bizarre slopes, which may offer little protection for the HF driver.
Design of a proper passive crossover starts with the specific parameters of the drivers, horns and orientation, and ends with testing of those components with real capacitors, inductors and resistors, and substituting parts until the acoustic results match the desired slopes.
