IR problem with bass response

Good evening everybody

I wonder whether you have the same "problem".

For a couple of years now I'm went directly to the board with an IR loader of some sort. It is so much easier, cleaner, faster than putting a mic in front of a cab.
However, when trying out different IRs, it is overwhelming how fundamental the differences are in an annoying manner. I know that a different cab gives me a different sound, but not like this. Definitely less when using a guitar. Something in the lows makes something go haywire.

I had workarounds like choosing one IR, dial a good sound in and set+forget. Or I use a parallel path in the Helix, split with a X-Over and then only have frequencies above (e.g.) 200Hz be affected. That way it is already much easier to compare the cabs.

Whereas that works, it is slightly inconvenient and not possible on a Mooer Radar for instance. I wish Line6 would give a LPF for the IR block which would leave the signal unaffected, not cut it like it does now. The normal LP/HP filters come in handy, but I'm missing the option to leave a portion of the sound unaffected.

Is it possible to alter the WAV file to not affect lower frequencies? That you could manipulate the file somehow?

I'm not looking for cab recommendations or workarounds, since I have something that is working. I am a bit amazed how IR are so widely used but to go through them with the bass takes a huge amount of tweaking every time you pick another one.

Tell me... am I alone in the wind or do others feel the same?
 
Different strokes for sure....
What is your listening frame of reference?
On stage via FR speakers/ monitors?
Studio monitors?
FOH Sound system?
In-ear monitors?

Does your sound mixer share your POV?

There are digital tools for creating IRs or modifying existing ones to your taste, but I've never home-brewed myself. Seems like you should be able to do what you want by altering your IR .wav (HPF at 200Hz) and blend it with a flat EQ IR .wav with a LPF at 200Hz to create a new .wav, but I've never tried this.
