Plan #1 - Sealed Subwoofer Enclosure

 

sealed subwoofer outputWinISD recommends a 1.55 cubic foot box for our sealed enclosure. We'll achieve this by using 3/4 " MDF for the enclosure with external dimensions of 15.5" x 24 " x 10 ". This will be a simple rectangular box. Modeling the enclosure we see that it has a 87 dB sensitivity and a -3dB (half power) frequency of 42 Hz. This box should give very strong output when it is combined with the 12dB/octave boost provided by most automobiles.

 

Here is the layout of our subwoofer enclosure. We will need to cut the following pieces:

 

SIDE
QUANTITY
DIMENSION
TOP/BOTTOM
2
24" x 10"
FRONT/BACK
2
24" x 14"
SIDES
2
14" x 8.5"
