Hello. I have a new pb2-ultra in a fully enclosed 12x17 room. At my listening position the bass seems weak when running test tones with Avia. When I go to the corners of the room the bass is verry loud according to the spl meter. I have tried moving the sub around the room with similar results. It seems that maybe my seating area is in somewhat of a bass null with the pb2. I am about 2/3 the way into the room lengthwise with a classic 7.1 layout (12x17 fully enclosed rectangular room) so the response should be good here I would think according to what I have read about placing the seating area and so on. I can not move my seating area anywhere else. My question is it possible that maybe a front firing sub could give me better performance in this room? I know it is common for bass to concentrate in corners, but it just seems wierd that such a powerful sub is doing this or maybe it is not wierd. The reason I ask about a front firing sub is in my last house I had a similar room, although a bit bigger with a front firing hsu vtf-3 in which the gain was not turned up nearly as high to get to 2-3db over reference. It would seem that a more powerful sub in a smaller room should not have to have the gain set higher which is why I am wondering if a front firing sub might be better in this case.
