The problem is the speaker/room interaction, as is 95% of all problems that people experience with audio.
Do you have acoustic treatment on your front and rear walls?
Have you treated the reflection points on the side walls?
Have you experimented with speaker positioning, making sure to have ample space from all walls?
If the answer to all of these questions is *yes,* than you have purchased a pair of shrill-sounding speakers. (I have nothing to contribute here, as I haven't heard them)
