Watch Allyn explain how to determine port area amount when designing enclosures, with Term Pro software. He takes us step by step on determining port area when designing ported sub enclosures ... calculating port area with aero ports? - SPL & SQ ... That's really how more port area (such as in a slot port) helps you, by decreasing air velocity through the port. So if your port velocity is 13 m/s with a 100 sq. inch slot port and 13 m/s with 60 sq. inches of aero port, there should be no difference. Sealed or Ported Subwoofer Enclosures - Which is Better ... Ports/Vents can be round, square, triangular, rectangular or any custom shape you can think of. For example, the port of the enclosure shown above is a rectangular slot port in the front of the enclosure. The port/vent shown below is triangular in shape and is also a slot port design but is located on the side of the enclosure. Vent tuning of ported systems - Troels Gravesen The results from the un-damped box and k = 0.732 should fit for a port flanged at one end as has been performed. So, apparently something is wrong. It has to be said that the difference between a double-flanged vent and two free ends was less than 0.6 Hz, so when the vent is - at least - sharply flanged this does not make a whole lot of difference.

Slot port enclosures: successes and failures, please post ... Hey Folks, There are many who are looking to build slot ported enclosures with as narrow of a port as possible. Based on searching around, I have seen some comments like "keep it to a minimum of 2" height" or "don't go lower than an 8:1 width:height ratio", but I couldn't find any really good data to back those claims up, hence this post. tuning non-typical port shapes | TalkBass.com The slot port offers you the largest amount of port area that consumes the least amount of baffle board space. By definition, a slot port uses three cabinet side walls to enclose it's air volume. The fourth wall is the inner port wall. The correction factor for slot port total length is 1/2 the height, added to the port length. Convert round to slot ports - Techtalk Speaker Building ... Convert round to slot ports 06-02-2006, 08:49 PM If I needed a 2" diameter, 15" long port in an enclosure (this is for the TB W8-1363SA, per Wolf's recommendation), is there a particular formula or rule of thumb to follow if I want that to be a square slot point instead?

A slot port requires more port area than a flared port to minimize port noise. We generally use a rule of 12 square inches of port area per cubic foot of internal volume of the custom sub box. You may go with a larger port area, but this will increase the total volume and length of the port. Convert round to slot ports - Techtalk Speaker Building ... Re: Convert round to slot ports It's gonna be a long, shallow box, but I havn't had a chance to figure some dimentions yet. It would probabl be better to figure for a 3 or 4 inch square port, to reduce port length. Slot port enclosures: successes and failures, please post ...

Calculating Subwoofer Port Length - Not So Simple - AVS ... for ports that dump cleanly into free space, end correction is low, something like k=0.732 on a baffle and even a little lower if the port has no baffle. for slot ports that are on the ground, the boundary in front of the port and behind the port have the effect of synthetically extending the length of the port.
