SAMPLE ENCLOSURE SIZES
This page is offered ONLY as a starting point" for box construction. Although our woofers work well in a wide range of box volumes, many people try to build boxes too large assuming they will get better bass response with such monstrous sized boxes. This is NOT acoustically correct and you nee 13113v215n d to pay attention to the recommended volumes and predicted performance data when making your box decision. On the other hand, the more common mistake is to jam a big woofer in an extremely small box and have virtually no low frequency response due to the "choking" effect of an undersized box.

To help understand how large a "cubic foot" really is we have provided the drawings and tables below with some common relationships for height, width, and depth. These are not "magical" sizes or relationships in any way, just popular sizes that will fit in most vehicles and perform well.

All dimensions are stated for exterior sizes and are calculated with compensations for box wall thickness using 3/4' wood. Also, each volume is adjusted for air volume displacements for a woofer (average 0.15 cu ft for 10/12' woofer) and a mid size port (3 dia. x 7' long). Please be aware of the small impact that box size fluctuations has on the end sound quality: loudspeaker enclosure interior size deviations of +/- 5% from ideal are rarely heard. In addition, interior objects such as port volume displacements and cross braces can usually be forgotten about in all but the smallest of boxes.
