The two most likely explanations, which have been suggested:
1. Ability of low frequency signals to pass through materials, thereby making it seem louder outside the regular listening area. (Example: the car audio "boom and thud" subwoofer systems that can be heard a block away.)
2. Wave interference or cancellation in your room. If this is happening, the low frequency signals at your listening spot are actually less that they could be. You might want to invest in having an A/V pro come to your house and do an RTA analysis.
