Adding a lot of absorption that does not absorb all frequencies the same can give the impression of reduced highs. Since absorption affects decay times, having sound continue to bounce around the room after the source stops means there's more total energy to be heard. So adding absorption that's too thin to absorb low mids and lows leaves more LF energy in relation to the highs it does absorb. The two main solutions are:
1) Have plenty of bass traps to complement the HF absorption.
2) Don't put absorption all over very surface because that's not needed anyway. Instead, focus on the reflection points at the side walls and ceiling, and also the rear wall behind you.
