I’m trying to do my best to isolate an octave (31.5 midpoint). I figured a parabola would be the best target curve. Any ideas on how to create one? Or at least create a filter to attempt to isolate a small range of frequencies.

Use the crossover filters (Generic - generic) or LP/HP (Generic - extended).

Will a minidsp take those or do I just use those to create the curve and then Eq the curve using the auto-eq function

You can set up crossover filters in the minidsp using its own controls.

I have done this but I can’t get it narrow enough. The crossover gets close though.

Is it possible to create a notched biquad to load?

You can apply octave or one-third octave filters to measurements using the Filtered IR graph.
