SLOT port calculator vs square port calc???? - Subwoofers.

The other more simple rule of thumb is when the slot port uses 3 walls then reduce the port length by the effective diameter of the port. i.e. if your slot port is 14.5" x 2" then the effective port diameter is ~6" so reduce the port length by 6".

That calculator is wrong. It assumes that a port of 1/2 the diameter (1" vs 1/2") is half the surface area. I tried it using a 4" port vs a 2" port and it gave me exactly half the length. That is simply not right. Tuning is a function of the volume, surface area, and length. A 1" port is.79 sq in vs.39 for the 1/2".

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. Slot Port Area Calculation. Let’s use a 14″ long port that is 4″ tall (width). To calculate the area of a slot port, use the following formula: Slot Port Area = length x width. Example: 14 X 4 = 56 of port. Conclusion. A subwoofer port calculator is very important because it determines how well-tuned your subwoofer will be.

Sep 11, 2013 · An overview of the process by which the simulation programs calculate port length is as follows: Calculate the effective length L EFF of the port based on box volume, box tuning frequency and port cross-sectional area A. Calculate the actual length of the port L ACT using an end correction whose value is proportional to the square root of the. Jan 21, 2012 · It LOOKS like the length of the port is fairly proportional to the cross-sectional area (to keep the same tuning in the same size box). NEW port (1.76 ) divided by old port (3.14) = 0.56. Multiply THAT factor (0.56) times the old port length (6") to arrive at the new equivalent port length OF 3.36". Even slot ports should be flared. The normal method of flaring a slot port is to use a rollover bit in the router to run all the way around the port opening. If you are moving a lot of air, you may find that this is not sufficient. One solution is to take a length of PVC pipe and split it lengthwise into quarters.

The "Minimum Port Area Required" result is how much port area you will need to keep port velocity under about 30 meter per second for slot ports and 32 meters per second for aero (or other round) ports. Port velocities above these numbers are where serious port compression sets in and you begin to lose a LOT of output. In this video I provide examples of how box volume, tuning frequency and port cross section impact the length of your subwoofer's port. Watch this video and.

Step 4: Port Length. The sound of the system is somewhat tunable via changes to the port length. As we learned in the Why Go Ported section, the port area needs to be in proper ratio to the cone area, so the DDBox system uses variations to the port length as primary means of tuning frequency mods. Refer to the DDBox site chart to 23″ long.

Follow by inputting the diameter (D) of the vent (s). Then, fill in the volume (V) of the subwoofer box. Input the tuning frequency (F). Finally, adjust the end correction factor (k). It is common to assume that k = 0.732, hence the default value set in the port length calculator. Feel free to change it to fit your needs. Calculating Port Size. Calculate Port Size. The box port can be calculated with a simple formula. Box volume in cubic feet X 16 (the amount of port area in square inches per cubic feet of box volume). For example, 3.4 cuft X 16 sqin= 54.5 square inches of port area. Try to stay within 10% of this number. The port length should be 16 inches deep. 4 inch port, 3.68545 cf, 30hz gets 7.284inches (+1 for the flares) is 8.284. It's easier to round down to an easier fraction so 8.25inches. So with those dimensions and a 4 inch aero port 8.25 inches long, you'll be tuned to 30.05hz. When you are a beginner designing boxes, its easiest to use whole or half numbers for dimensions.
