*Efficiency (1W/1m) is not an accurate indicator of a subwoofer’s output capability and should not be used as a
comparison to other subwoofers to determine which one is “louder”!

•Enclosure dimensions listed are external dimensions which assume the use of 0.75 inch (19mm) thick material. If you are using
0.625 inch (16mm) thick material, subtract 0.25 inches (6.5mm) from each dimension. Do not use material with a thickness of
less than 0.625 inches (16mm).
•Enclosure volumes listed are NET internal volumes. Driver displacement, port displacement and brace displacement must be
added to obtain the final gross volume. The dimensions listed have already taken this into account.
•When using two subwoofers in a common enclosure simply double the required volumes and use two of the recommended ports
(when needed). Likewise, when using three subwoofers in a common enclosure simply triple the required volume and number
of ports (when needed).
