I started out with a 4 cubed box and ported it with 2 4" pvc tuned to 37htz. It's all I had at the time and could not go get any more. I've been recovering from a 3rd nasty shoulder surgery so god bless my 15 year old for helping me with a great install.
So the other day we decide to change the port. I pick up an 8" concrete tube not knowing it's real size is 7 3/4". Ok a few adjustments to the port and we tune it to 35 htz. Not a good idea. Before the large port man this sub hit hard. Like you can feel the air in the car pass your face and the windshield flex wipers vibrated off the glass so on and so on.
Now I had to raise the subwoofer out put on the stereo way up and still can't get the air to move like it did with the smaller ports. Barely get any flex wipers don't jump any more and although it sounds ok. It does not sound as good as before. Why would puting one large port instead of 2 smaller ports that equals the same circumference sound soo different?
I'm ready to go back to the 2 4" ports.
