Do you use any kind of room treatments? What is on the walls? Floors? How far back are you sitting and are you sitting against the back wall? Are the speakers toe'd in or facing straight towards the back wall? Are the speakers in corners? This will reinforce the bass a little.
The room is usually the problem and you will want some treatments for absorption, diffusion, reflections, etc. For now, throw some rugs or towels in front of the speakers and hang some rugs or something on the walls to tame reflections. Overstuffed furniture can help absorb some of the sound bouncing around around the room.
