I've ran into a small problem in the middle of building my new box for my 4 10's. The new box contains 45 degree cuts...which I hate cutting, but that's beside the point. Between the partial vent wall and back inside wall of the box is supposed to be 2.75". I noticed when checking things around that its about 3/16" over, on the bottom of the box yet maintained the 2.75" on top. I checked further and found that the vent walls are a bit angled(not straight) up and down yet it looks as if they are straight. Question is, if I slap on the tops of the enclosure w/o fixing this, will it affect any sound or anything at all?
