Enter the length, width, and height into the calculator to determine the volume of the enclosure. This calculator can also evaluate any of the variables given the others are known.

Enclosure Volume Formula

The following formula is used to calculate the volume of an enclosure.

V = l * w * h

Variables:

  • V is the volume of the enclosure (cubic units)
  • l is the length of the enclosure (units)
  • w is the width of the enclosure (units)
  • h is the height of the enclosure (units)

To calculate the volume of an enclosure, multiply the length of the enclosure by the width and then by the height. The result will be the volume of the enclosure.

What is an Enclosure Volume?

Enclosure volume refers to the amount of space available inside a speaker or subwoofer box, often measured in cubic feet or liters. It is a critical factor in determining the quality and type of sound produced by the speaker. The size and design of the enclosure can significantly affect the speaker’s performance, including its frequency response, efficiency, and distortion levels. Different types of speakers require different enclosure volumes to function optimally.

How to Calculate Enclosure Volume?

The following steps outline how to calculate the Enclosure Volume.


  1. First, determine the length of the enclosure (l) in units.
  2. Next, determine the width of the enclosure (w) in units.
  3. Next, determine the height of the enclosure (h) in units.
  4. Next, gather the formula from above = V = l * w * h.
  5. Finally, calculate the Enclosure Volume.
  6. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

length of the enclosure (l) = 5 units

width of the enclosure (w) = 3 units

height of the enclosure (h) = 2 units
