Cj Kumz Posted June 16, 2014 Report Posted June 16, 2014 Hey hey. Just a quick clarification here. What is the highest port ratio you can have on a slot port. Is 1:5 ok???

Joe X Posted June 16, 2014 Report Posted June 16, 2014 Estimated to be 9:1 but I wouldn't recommend that, 5:1 ok.
Cj Kumz Posted June 16, 2014 Author Report Posted June 16, 2014 Ok thanks a lot. Not too conversant with slot ports lol. How does this look for sub up port back. Amp: 1 x Sundown saz 3500d @ 2ohms.

Triticum Agricolam Posted June 16, 2014 Report Posted June 16, 2014 With slot ports the farther away from square you get, the less efficient your port becomes. It starts acting like its smaller than it actually is. For example a 1:5 ratio port is only going to flow 81% as much as a square port would of equivalent area. A 1:9 ration port will only flow 73% as much. So if you are going to use higher ratio slot ports, you should make them a little larger to compensate.

Chase Sanders Posted January 14, 2016 Report Posted January 14, 2016 so let me get this a 1:1.1 is about darn near perfect I'm doing a upward port thru the rear deck 1994 nissan sentra. what ya'll think of that idea my car is more responsive when facing forward with port or upward to rear deck.
Triticum Agricolam Posted January 15, 2016 Report Posted January 15, 2016 Yup, should work great as far as port ratio is concerned. "Nothing prevents people from knowing the truth more than the belief they already know it.""Making bass is easy, making music is the hard part."Builds:
