crossover design

Looking for a good crossover design for a 2 way system 4th order with crossover point at 2500.
You may need to go to the madisound or Parts Express forums where there's plenty of knowledge in system design. More information will be needed too.

Are you looking for an active crossover or a passive one?

Try to give a few more details to the design and you'll probably get quite a few good answers to your question.

What drivers, have you measured the T/S parameters, or is this just current manufacturers product you wish to tweak, and if so why, and what are looking to hear from it.
