I agree with Bosso's post for the mid and upper frequencies but not for the sub frequencies. The post describes how you hear the direct sound first then the reflected sound. This holds true except for the sub which may have the speaker not pointed directly at you (like the LFM-1) so all that you get would be reflected sound. I don't currently us any EQ but in the past I have used it for attenuation only which did seem to help.
