Okay i need some advice here (ill have a drawing of the room when i get home, at school right now) The room used for HT is also used for 2 ch audio (with the JBLs, Paradigms are for HT, which is fine. Sub is not used for 2ch audio). However, the way the speakers are positioned, and the room is shaped, is causing huge bass cancellation at listening position. The room is somehwat rectangle, except for the left there is a small area that extends out about 3 feet, and the back of the room, where half of the back wall is a closet, the other half is indented about 2 feet a nook. and in the nook is a book case. (not to scale) On the couch at listening position i can barely hear any midbass, but if i sit up on the 'back' of the couch and lean back towards the back nook i can hear all the missing bass. This is where the RED is. I have a few sound-absorption tubes (i forget what they're called at the moment), normally the larger ones (for lower frequencies from what i understand) are placed at the two front corners of the room. I tried, however, placing one of them in the nook where the bass is loud to absorb any bass from reflecting back out and cancelling, with no luck. I tried sticking in blankets and pillows in the bookcase to try and do the same thing with no luck. Any ideas on how i could remedy this?
