That could be the response of your speakers, or it could be comb filtering from nearby reflections. Try moving the microphone one foot in any direction and see if the frequency changes. If it does not change, it's your speakers. A loudspeaker dip in the "harshness" range around 2 to 4 KHz is common, and some manufacturers do that intentionally to make their speakers sound smoother. I don't agree with that! But it's common anyway.
