3 Enclosure Recommendations The ProSeries and Competitor Series subwoofers ar e designed to deliver optimum performance in small sealed enclosures. The Generator Series subwoofers ar e designed for either sealed or ported enclosures. The fol- lowing are the r ecommended enclosure volumes: Sealed Enclosures 12.
4 Calculating your enclosure volume: Internal dimensions Height (inches) x Width (inches) x Depth (inches) = Gross Internal Volume (cubic inches) Remember to account for material thickness when determining exter nal dimensions.
5 Building an Enclosure Use at least 3 ⁄ 4 -inch MDF to build the enclosur e (1-inch is preferable). The joints should be liberally glued with car- penter’ s wood glue and screwed together with wood screws and sealed internally with a bead of silicone rub- ber or hot melt glue.
6 Locating Subwoofer Enclosure in V ehicle The placement of the enclosure is one of the most important factors concerning installation. As each vehi- cle’ s interior acoustics are dif ferent, experimentation is the key to optimizing performance. Hatchbacks/Sport Utility V ehicles Locate the enclosure in a r ear corner for maximum out- put.
7 Sedans Provide as clear a path as possible into the cabin by venting through a folded-down arm rest, venting thr ough the rear deck, or venting thr ough an unused speaker opening in the rear deck. Keep any r estrictive materials such as wood, hard plastic or metal fr om directly block- ing the subwoofer .
