should I worry about acoustic coupling?

I just heard about acoustic coupling with subwoofers and now I'm kind of confused. I'm in the process of building a pair of 3 way computer speakers, and because they are computer speakers, the woofers will be pretty close together. (Probably three to four feet?)

I know that acoustic coupling yields a 3 db boost at lower frequencies. Would I have to worry about an overboosted bass response? Would I have to eq this out? I prefer neutrality.
 
Acording the size of your project and relative to the drivers you have chosen, you also can make a 2+1 ways, where the +1 is a sumned R&L channels standalone bass driver, you can putt bellow the desk or behind the screen...


Works fine if you use for instance a full range for satelites with a cut-off below 150 hz...


just 2 cents
