liftedranger08 Posted July 6, 2009 Report Posted July 6, 2009 I have a box that is 2 cubic ft for my dc lvl 4 12. I was looking at some vids and saw some ports on the outside. I have some 4" pvc pipe laying around and i calculated a port length. I figured it up and i got 1 4" that is 12.5" long and it will be tuned to 33Hz. I was thinking about putting sup up, and have port out the side so the air would bounce off the door. This is going in a ford ranger extended cab. How would this sound compared to a normal slot port. I just want something different because nobody around here has ports like this.

Kian Posted July 6, 2009 Report Posted July 6, 2009 did you use www.psp-inc.com? cause that seems like a very small port for a lvl 4.

Torres Posted July 6, 2009 Report Posted July 6, 2009 i also think it's kind of a small port for 2 cubes of volume. i'm not very familiar with aero ports, but some say to use 1 4" port per every cubic foot, and i believe it was ray that said he uses a 6" port for every cubic foot. just as an idea what to go by.

Airborne Posted July 6, 2009 Report Posted July 6, 2009 I have 1 6" aero on 4 cubes and it slams. Quote

liftedranger08 Posted July 6, 2009 Author Report Posted July 6, 2009 The only thing i could find on that site was the port length calculator. I was going off 14-16 sw inches per cubic ft and the 4" gives me 50 sq inches.

Torres Posted July 7, 2009 Report Posted July 7, 2009 how do you figure? one 4" port = 12.56 sq inches. keep in mind tho that they're more efficient than a slot port, so the port area does not necessarily need to be 12-16 sq inches per cube (i use 12-16 sq inches) Quote

I was going off 14-16 sw inches per cubic ft and the 4" gives me 50 sq inches. one 4" circle port gives you 12.56 sq. inches of port area.

Torres Posted July 7, 2009 Report Posted July 7, 2009 that sounds a bit better as long as you have enough room for it Quote
