Once I had these filters in place and ran my AVR's EQ (MCACC), I found in order to get the subwoofer to EQ to -6db (which is the recommendation for Rythmik subwoofers), I had to turn the subwoofers gain knob all the way up. This was because I had to subtract so much db using PEQ to tame that peak. Turning the volume knob all the way up to get to -6db in MCACC EQ on the AVR undesirable because it makes a light humming sound when not being used. Using the Line In on the subwoofer input inherently brings with it a +6db gain. However, it also enables LPF/crossover on the subwoofer itself. Because of that, I turn the knobs on the subwoofer all the way to their lowest setting for delay/phase to 0, highest for Crossover to 120Hz, and lowest LPF slope to 12. With those settings on, the effects are minimal, other than limiting range to 120hz instead of 300hz. That's fine though as all of my other speakers play above 80hz (and lower), and I set the AVR crossover to 80hz.
So short story - I'm using Line In not because I want the sub to manage those settings, (in fact I don't), but rather to get an extra 6db gain. The sub is now +/-5db flat from 20-100hz with its volume knob around 2 o'clock.
I think 120 Hz LPF might be a bit of a mistake, at least in terms of consistency and flexibility of tweaking.
I would set subs LPF to maximum, or turn it off if thats even possible. That way, your subs response gets EQ across whole range and then, depending on your needs (for best response) you can adjust crossover + slope wherever you want.
The way you have it now, you have crossover set by AVR with 12/24 slope and additional 120 Hz LPF with 12dB slope which is technically fine...as long as you don't turn it off.
Also, I don't really like the looks of that 60-100 Hz area...even with 1/6 smoothing
