The setup that I want to build will require that the subs are about 3-4 inches from the back door. Will this be a problem (they will be far enough away that they will not physicaly hit the door)? The subs will be hitting one flat surface because the doors in my back fold down and up to open. I am just worried that this might muffle the sound of the subs. What do you guys think?

 

Many people intentionally set up their enclosures this way.

 

Really? I guess I am good to go then. Thanks dukk.
