Does cutting certain frequencies somehow boost others?

I have my mix HP at 26hz and LP:at 16kHz.I sometimes load professional tunes in Ableton to reference how elements should sit in a mix in relation to each other, but when I did it was peaking at about 2.5db over. I knew this couldn't be right, so I checked to make sure it wasn't routed to any sends and that there werent any other effects on the master channel other than the filters. I then turned the filters off and the song began peaking at 0db. The filters had no resonance on them, and to make sure it wasn't them, I put in ableton's stock EQ8. It was still at 0 until I pulled a band down, and the the song started peaking at 1 to 2 over again. What's the deal???

The EQ introduces phase shifting which causes relative boosts or cuts in volume at certain frequencies.

why are you cutting at 16khz on the whole mix?

this lol
also try a linear phase eq

Minimum-phase EQ's, like AxeD said, causes some frequencies to shift in relative position to others. The problem is that not all frequencies shift or not all by the same amount, so compounding the composing frequencies of a sound after a minimum-phase EQ will have a different technical volume than before the EQ at some points. In some cases, this can cause the volume to go up as frequencies are cut. Linear-phase EQ does not have this problem, but has other issues of its own.
Skimpi makes a good (but unrelated) point, though. It's usually not a good idea to cut your entire mix at 16kHz. If it sounds better that way, then sure, there are no rules, but there are audible frequencies above that threshold that are often important to a mix.

I noticed my mixes tend to sound a little thin and hissey otherwise, on all systems I test no just my phones. I guess I could LP higher and focus on making the elements themselves have less high end, but idk it stlll sounds good this way
