Okay, I had some time to mess with the profile over the weekend, and I think I was able to improve it. I was following the same guide, and trying to achieve a relatively flat response with a bit less dynamic range to improve clarity at lower volumes. If you prefer more dynamic range, or plan on using the speakers at full volume most of the time, you can push the input level down on the multiband compressor to -6 or -8 db, and you will get basically full dynamic range (or at least as much as you’re going to get through laptop speakers).
Compared to Cab’s preset (that was admittedly made for entirely different speakers), mine has a bit more punchy bass with a less muddy low end. The highs are less pronounced, but in a good way in my opinion. The mid range as a whole is just a bit more flat, and it’s easier for me to make out details in the base, low-mid, high-mid, and highs when they are all present. I did test it with a sine sweep, and there are still noticeable peaks at 250Hz and 2500Hz to my ear, but not nearly as bad as without the profile.
I will say that I’m no audio engineer, but I am a long time musician, and lover of music of many genres, so take the profile with a grain of salt, and feel free to compare it to Cab’s original profile to see what you prefer.

I’ll update again if I manage to make more improvements with fresh ears later on.
