I've been reading the Loudspeaker Design Cookbook and found the effects of lobing due to driver placement on the baffle, but am still left wondering two things. Use the picture below as a reference to how the placement would differ. Assume same port length and volume for each. #1: The port ends in a different location inside the box, does this have different loading effects on the sub? From appearance, it would seem that the air flow in each would be somewhat different and affect the subwoofer? #2: What happens to the subwoofer and response as you move it closer or farther away from the port? Is it best to have it centered or off to a particular side?
