RECOMMENDED ENCLOSURES
Please note that these enclosure volume recommendations are for the internal airspace inside the enclo-
sure and include the displacement of the subwoofer and ports. When choosing your enclosure type, please
pay close attention to your specific woofer, failing to use the correct enclosure may result in lower power
handling and poor sound quality.
To calculate the internal airspace required, take the internal
dimensions of the box. First multiple these number by themselves and then divide this sum by
1728. (W x H x D) / 1728.
Please contact your authorized PowerBass Autsound dealer for other designs
and specifications.
(Even though these subwoofers can be used in a ported enclosure, PowerBass
recommends a sealed enclosure for optimum performance and sound quality.)
