I've got a pair of Odyssey Audio Lorelei's. Narrow fronts (about 8").
I've ran a freq test on them and found a "hump" at about 35hz followed by a dip at about 75hz. My speakers are about 8 feet apart.
I corrected this as well as I could by placing 2'x4' base traps between speakers and cabinet.
Is the purpose of the Fix to correct this type of response?

2nd is the "correction"
3rd is the layout
