Bass Suckout in a Square Room - Remedies and Solut

Hi All,

My problem is I've got major mid-band and lower bass suckout with my speakers.
The bass dissapears in the seating position. But if you stand up either side of my sofa the the bass returns.
I would like to hear from anybody who has a similar problem and what solutions they use to eliminate the problem.
I can't move to another room in the house. But this is a dedicated hi-fi room. So there is a degree of flexibility.
Thanks
Meth

Move things around. One of my audio rooms is nearly square. In fact, at 16x15x8, it approximates a half cube. You will have to move the speakers and listening position to find an useful arrangement. RPG makes an interesting program to help with this:

The sofa is not the cause. If it is sitting in a null, moving it will not help but I have yet to find a sofa which is such a good bass absorber as to create a null.

Getting the listening position off the back wall and repositioning the speakers is important as is the use of true bass traps (at the intersections of room boundaries) to reduce both nodes and nulls.
