Sealed enclosure
This type of enclosure is classic and the simplest to build among most installers.
The box volume will directly impact the performance of the subwoofer, it is
important to make sure the enclosure is properly sealed. Use some type of
sealant on the seams as this will ensure a solid construction and prevent air leaks.
Larger enclosures will provide a flatter response and deeper bass where as a
smaller box will provide a generally higher output for greater SPL. All sealed
enclosure designs should be filled to 50% with loose ply-fill. The use of poly-fill
will slightly decrease efficiency but will deepen and extend the low frequency.
Primary advantages
• Small enclosure
• Good low frequency extension and control
• Simple to build
• Excellent for sound quality
Calculating volume
Measure the available space for the enclosure and using the formula (H X W X L
divided by 1728) determine the appropriate measurements needed in order to
achieve the desired cubic enclosure. If two facing sides are of uneven lengths
add them together and divide by two.
The enclosure recommendations listed are external dimensions using 3/4” thick
wood. If you use 5/8” material subtract 1/4” from each dimension, we strongly
recommend not use material less than 5/8”.
*Note the enclosures listed in the manual account for the driver displaceme
nts.
