Subwoofer Vent Length Calculators - Diameter of Vent

sorry for this newbie question. the port is going to be shaped like an L, now would the length be both slot walls added together, or just the wall that is running along the back of the box? i already know the box dimensions and port height, width, and length. any help would be appreciated. sorry if this is confusing, i don't really know any terminology. Calculating Port Size | Depth and Port Area Formulas Mar 15, 2016 · How To Make A Slot Port. To calculate the slot width that would make a total area of 54.5 square inches, and we use 14.5 inches as the height: divide 54.5 by 14.5= 3.76. Round that figure to nearest ¼ inch, and you get an offset measurement of 3 ¾ inch wide. The slot port would be 3 ¾ inches wide by 14 ½ inches tall. Calculating Slot Port length - Advanced Discussion - SSA May 05, 2008 · 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 8 Basic Diagrams On How To Measure Port Length Aug 21, 2007 · Well a while back i made these diagrams as i was speaking to someone (PowerNAudio, probably one of the nicest guys ive ever spoken with) who was teaching me how to measure the port length correctly, so you know what length to put into the tuning equation to get the correct tuning frequency for your port.
