Posted January 22, 201015 yr Like the topic says. Does anyone know how accurate the numbers are?Port Length CalculatorThanks
January 22, 201015 yr If your worried about accuracy do the math yourself.It appears fairly accurate though.
January 22, 201015 yr subtract 1/2 of port width if your using the walls as part of the port and that would be the right physical length.
January 22, 201015 yr You should remember that you design the port based on the woofer, not on the enclosure.
January 22, 201015 yr based on enclosure, woofer, and power going to the sub too.T/S parameters have the largest impact on the design of a port, if you are ever unsure that's the safest thing to design around.
January 22, 201015 yr Port velocity changes with box size, tuning, and input power. And port area but that's part of the port design.
January 22, 201015 yr based on enclosure, woofer, and power going to the sub too.T/S parameters have the largest impact on the design of a port, if you are ever unsure that's the safest thing to design around.Explain what you mean. I assume you're talking about what tuning frequency would sound best with a given driver?

January 22, 201015 yr The sites accurate, it already calculates end correction into it, but it uses the net volume of the enclosure. Meaning it calculates the tuning for the volume you enter which should be after all displacements including port, sub, and any bracing.
