Hi guys, i just got a new subwoofer a hsu vtf2 mk4, i had before ia dayton 100 and pioneer sw 8mk2 that came with my pioneer 5.1 system. The problem now with my single sub is that i seat rigth in the middle of the wid of the room, now im in big dip. im loosing about 10 to 15 dbs that if i just move two feet to the rigth or left, try diferent locations for the sub but its all aboute the same. Now i could just move rigth? But then what happens to my speakers symetry or my tv viwing angle. Is adding a second sub the only answer? My room dimetions are 18'4 L x 14'9 W x 8'10 H any sugestion on what to do?
