How do you improve bass response in a null?

My listening postion on the sofa is unfortunately in somewhat of a null, thereby reducing bass reponse. Since I use the room for both 2-ch & HT, I like my position to be centered on my 53" RPTV, which by necessity has to be centered on the front wall.

How does one reconcile optimal sound with optimal viewing angle? If I were to move my position on the sofa, I'd have to slide both speakers in the same direction in order to stay centered between them. While doing this, it would upset the balance for home theater, not to mention having one of the speakers blocking a portion of the screen.

Is there a simple solution to this problem that I'm not realizing. If the centerline of my room is a null zone for frequencies around 40hz, would moving the sub have an effect. Or is this room location always going to be in a null zone regardless of the sub's position?

Anyone got any theoretical or practical experience with this problem?

Thanks.

I imagine experimenting with sub placement would help. Also, you could move the mains either forwards or backwards a foot or two without changing the fact that you and the tv are centered between them. That might work. Less likely to work, but still a possibility, is to move the speakers slightly farther apart. I'm guessing you've found the right spot for the mains though, so I'd try the sub first.

How about moving the couch a tad further back. You don't have to muck with speaker placement much and this would change your listening point of perception. Sean

You didn't state where the sub is currently located. The optimal position for best bass loading is normally in a corner of the room, where there are three adjoining surfaces. Sometimes moving the subwoofer only a few inches will make a significant improvement.
