EDIT: the thread have update at #5

Software: Equalizer APO
This method work on any Windows after Windows Vista and with any sound card.
Motherboard built-in sound card may against the settings, so if that happen(no effect), find sound card like ASUS XONAR DX.

The issue is Tiamat 7.1 V2's main speakers have week ability on low-frequency(20~110Hz),
this cause in normal music playback | gaming | movie or without LFE crossover the LF will sound strange, some audio band missing.

I did a all frequency listen test and I guess that the main speakers can play LF start from 70Hz, but full power around 110 Hz, so I decide to choose 120Hz as my LFE crossover point.

There are several issue then, the sound card hardware LFE crossover have bug that cause 20.8 db red area distortion on LFE channel, and Equalizer APO the Low-pass and High-pass is mismatch when crossover.

If you can simplify the explanation, it might help a lot. Otherwise, try some other EQ app

I post the thread just for share my LFE crossover solution and want some help about my gaming...

This is consider that your hardware LFE crossover algorithm have bug that caused bad sound result so use software solution to avoid that. Maybe you're using a sound card's LFE everything is good.
Ok. Good luck.
On the black box, set LFE channel to only two LED lights.
