Although it's been incorrectly touted as ideal to place four subs at each mid-wall location (since it offers consistent frequency response for each seat); this is NOT recommended because it will cause uneven frequency response for every seat and is also less acoustically efficient than just employing a single subwoofer! Thus the maximum available output level of four identical subwoofers placed mid-wall will be LESS than one subwoofer located in the front corner. In our opinion, this is a waste of power and money. We recommend avoiding this option for four subs unless you are stacking them for two locations.
Well, so much for my plan to do the four subs in each mid-wall. It sounds like the four corners is the way to go, but there's no good way to do that in the layout my basement will have. One corner is going to be a problem.
