Slot Port Ratio at George Ricketson blog

Slot Port Ratio. With slot ports the farther away from square you get, the less efficient your port becomes. The ratio of w to h should not be any more than 9 to 1 to prevent tuning shifts introduced by excessive friction between the rapidly moving air and the port's surface. For inputs, i included 'air temperature' (deg/f), '# of ports' (quantity), and a 'desired slot port height' (inches). It should be noted that. If port air velocity is fairly high then a slot port is preferable as port noise will be distributed over a large number of frequencies. Some people recommend an aspect ratio not exceeding 5:1 or so, but that may be unnecessarily restrictive. That’s it, just hit calculate; For outputs, i added 'port length' (inches), port. Check out our article on round vs slotted ports. For example a 1:5 ratio port is only. First, select whether you are using a round or slotted port. Since you are using a slotted port, select square under port type and select yes. It starts acting like its smaller than it actually is. Enter the number of ports, the internal airspace of your enclosure, and the tuning frequency you wish to use; I'm considering building a br floorstander design (approx 28 litres internal volume) that has a circular port:
