Vent tuning of ported systems - Troels Gravesen Dv = port diameter (cm) Fb = tuning frequency (Hz) Vb = net volume (litres) Lv = length of each port (cm) Np = number of ports k = end correction (normally 0.732) The value for k, the end correction, can be fine-tuned by using the following values to derive the appropriate end correction figure for each end of the port, then adding them together Long port options for subwoofers - subwoofer-builder.com Long Port options Some suggestions for when the port length is greater than the box size. When a ported subwoofer is tuned low, and uses ports large enough to keep airspeed to a reasonable level, the result can be long ports. Calculating Enclosure Volume – JL Audio Help Center - Search...
When calculating port length, let's say it says to use 26" long and you are, for example, using 12.56sq in of port which is for a 4" diameter port. Radius is 2" I thought to calculate slot port length was to take the 26" depth and subtract from that the sqin radius by converting the sqin value to a circle then finding the radius, which in this ...

Overview: This is a calculator for designing a L-Slot Vent Bass Reflex Enclosure. The formulas used in the calculator create a design that suggests the most maximally flat response in an anechoic environment based on the number of drivers, the thiele small parameters and the allotted dimensions specified in the user’s input fields.
Determine the port length. Measure the internal height, width and depth of your enclosure with your tape measure and multiply the results to calculate the enclosure volume. Enter the tuning frequency and port diameter in the applicable fields in the onlne calculator to get the recommended port length.
