The only information needed to use this calculator is the nominal driver size.

The EBP and Qts values should be considered for choosing between a closed or vented enclosure.

Width, height, depth values shown in the calculator results are the interior dimensions. No adjustment for the displacement of the driver is needed. Multiply the vent diameter result by 0.75 for dual vent tubes.

The back and sides of the enclosure interior should be covered with acoustical damping material. The backside of the cutout hole should be rounded to allow air to escape from the backside of the driver.
