Sprite Boombox Vent Tube Dimensions


2016-06-10 7:18 am
I'm building the Sprite Boombox. To save on costs I would like to use regular PVC pipe for the vent tubes. The available diameters differ from the suggested values available here: https://sites.google.com/site/undefinition/sprite

Instead of 35 mm (1 3/8") I'm using 37 mm. How can I calculate the appropriate length of the vent tube?

At the back of each chamber is a 1 3/8" diameter vent that is 5.75" long. This tunes the enclosure to 63 Hz, and will get an F3 of 51 Hz
