Need more info before we can help you. Are you trying to build a passive crossover for your speaker? What type of speaker is this? L/C/R? Subwoofer? 250Hz lowpass is an odd xover frequency for a speaker, unless that speaker is a component in a mulit-driver speaker cab.

250Hz is way too high for a subwoofer xover.

dark,

you are in over your head. i tried to warn you.

what order cross do you want?

how do you plan to level match the components?

what about baffle step compensation?

Listen. It's All Good.

You need to measure it.

Just a little forwarned..... I was setting up my AUX subs yeasterday for the hundreth time hahaha, i was experimenting with Hipass and Lopass. If i added lo and hi pass to them i had to invert phase. Now i knew this because i was running OmniMic at the same time. No way i would have known that with out MiniDSP software and OmniMic monitoring.....

This is not for the faint of heart....
