Default NEEDED diy low cut filter

there is a need for a simple 40hz/35hz active low cutoff filter with a very steep cutoff for the diy tapped horns. Anyone got a fairly simple circuit for one?
While we're at it a 12/24db 16khz or really steep 18khz would be rather usefull for the piezo crowd.

Another usefull filter would be a 100hz mic level balanced filter for vocal mics or an active line level version. Active would be 80/100hz steep cutoff and 16k cutoff.
