sarlindescent: Yes it should. I have an XS30 in a rather open 3,400 cu. ft. room and it slams the walls, vibrates the floors (laminate over concrete slab), my chair and myself. Matter-of-fact it often takes some of my metal art on the wall and moves them out of kilter, so the XS30se should even be better. I'd say you may be in a partial null area. Did you do a subwoofer crawl test to locate your sub in the ideal position for your listening area? I'd also check with some of the people here on how Audyssey has setup your system, because something seems very wrong.
