If you treat just the slap echo, you could end up with a tonal imbalance.The number one biggest mistake that folks do when acoustically treating a room, is to use too thin of a material, and then use too much of it to try and compensate.

Yes, it is a DIY note, BUT, it also has placement and SIZE recommendations.The big advantage with DIY treatments is it is easy to make them thick enough, with out breaking the bank. I recommend a MINIMUM thickness of 6" of acoustic absorbing material, placed as indicated in the DIY note, in the recommended size of wall panel.
This would mean for best results, that you would use two 3" foam panels, or thicker, in the recomended total size at the first reflection points on the side wall, and then as indicated or needed.
If the entire room is very live, then addition of a rug (if there is no carpet), or the use of room difussors hung on the wall (T-Fusors ala my note), or even Room Lens (a set from Argent will run $800, a DIY set less tha $100) to help break-up the slap echo conditions.
Note that a single thick panel of foam located in each ceiling corner of the room ca be helpful with slap echo situations, as an adjunct to the properly placed side wall panels.
