Is there a place where I can find existing filters for speakers? I am used to DIRAC Live where you build a filter based on the room layout but I am uncertain how to generate a parametric filter, I am assuming there is a third party tool that does it?

The required filter depends on room and speakers, so best to measure this, similar to Dirac. There’s various third-party software for measuring and filter creation, then load the filter into Roon. Some existing threads with lots of info:

This is what produced best result for me (I sit in a small room with concrete walls), but the way I did it should work well in bigger rooms and for different walls as well. This guide assumes you have a 2.0 or 2.1 system, and works best if you have a specific listening position and you sit in the middle of the sound, with an equal distance to left and right speak…

I’ve used this tutorial from OCA tuber, below. It did improve the speakers in my little office space while working from home. YMMV as usual.
