Working through OCA videos to create DSP filters

I thought I attached to to the first post, but I guess I need a zip file, let me try again. Hopefully it's attached here.

Thanks! I'll take a look with a grateful heart..
Btw, Is the polarity of your LSR310s inverted? It depends on the location of the subwoofer, but I think it's a good idea to compare it by clicking the inver button on the back.

It's on the 180deg setting at the moment.

My filter with the 98Hz correction pre-rings a little on Billie Jean. The one you shared adds a couple extra notes between each kick drum lol

It's possible to eliminate the pre-echo completely by chopping of the left windowing of that filter but the effect will also change.

Are you using your own crossover 80hz by connecting speakers to 310s?
Can I see the measurement by pressing the 180 degree button again? Of course, it depends on the position of the subwoofer, but I think the answer would be good if the polarity was reversed.

I am using DAC->310s->306p (using sub's built-in 80Hz crossover). I will try to take measurements with 0deg polarity setting (measurement file I shared is with 180deg setting).

When window length is dropped down to 30-35ms, all audible pre-echo is removed:

But it turns into a compromise between frequency response and phase response depending on the optimization strength. Still, phase will often end up much better than the original with an almost flat FR.
