The size of your subwoofer box dramatically affects how well it performs. For instance, if your subwoofer box is too small for the woofer that you have chosen, it is doubtful that you will get the desired bass effect. On the other hand, if you build a subwoofer box that is way too big for your woofer, there will be a lot of space left unused which can compromise the audio performance.

To make matters easier for you, here are some guidelines on how to determine the correct size of your box:

1.Measure your woofer

you should have this information handy in case you forgot to get it when you were buying the speaker, or it is still packed. If you do not know where to find this info, make sure to check if there is a manufacturer’s label on the box where it is stored.

2. Calculate the volume of your box

make use of your tape measure and calculator to arrive at the exact square footage of your subwoofer box before you start working on it. For instance, if you are using a 12″ woofer, multiply this number by pi since what you will need for figuring out the box’s volume is the radius of your woofer. Calculate the total cubic inches of this product and divide it by 1728 for better results. For instance, if you get a total of 14 cubic feet from your calculations, it means that the ideal size for your subwoofer box should be 2 cubic feet or 264 cubic inches.

3. Measure the inside dimensions of your box

make use of your carpenter’s square and measure from corner to corner or wall to wall if you are working on a rectangular design.
