I want to integrate my famous janis subwoofer to my system. I don't have the interphase-1 that belonged to it. So I'm constructing a active filter ( from the group buy). A third order filter at 100hz is required. That shouldn't be to difficult.
A variable phase 0-180 deg. is also highly recommended. So i thought a all-pass section should do the trick.
I'm confused about the math, if half the wafelength of 100hz is 6,8meter. With an allpass section i can compensate only for several tens' of centimeter.
please help
