[QUOTE="GammaRadiation, post: 7587539, member: 638609"] You want to minimize the interaction of the "air plug" in the port with the cone of the driver. It's a resonating system and the plug hitting the cone instead of springing against the volume of the enclosure can cause interference at the back of the cone. If it's constructive you're likely to cause turbulence and lose energy to heat (though you'll be really loud...at the back of the cone) or the cone will be flexing at an angle. If it's destructive you will witness a phenomena often called "unloading." That is, the cone of the driver interacting with the port will easily overdrive mechanically near resonance of the system rather than what is expected, minimum excursion near resonance. You'll also be losing a lot of sound because your port will lose velocity. In general, you want to have your subs away from the back of the port and have the front of the port near the subs.
