Posted July 26, 201015 yr My setup is 2 dd3512e sub and port facing the back. The port is in the center between the 2 sub. I seen some setup with 2 12's with subs and port facing back but the port is towards one end of the box and not the center. Is there any benefit to having the port on one end instead on the center, this would be in a trunk setup? Which would be louder?
July 26, 201015 yr It's application dependent, I've seen testing where a shared pressure chamber and a port on the side it gained about 3 dB.
July 30, 201015 yr To the ear you will hear little to no difference. Unless you compete regularly I wouldn't worry to much about it.
July 30, 201015 yr i noticed that with a port at one side of the box with port back subs back causes the sub that is closest to the port to bottom out first. thats why i went to a center port
August 2, 201015 yr i noticed that with a port at one side of the box with port back subs back causes the sub that is closest to the port to bottom out first. thats why i went to a center portSo the question then becomes- Did the one sub bottom out sooner than it would have normally or was the one farthest away just protected from bottoming out as early by something? Or I guess a third option, did you switch the subs around in each hole to make sure it wasn't just a variance in the two subs?
