Congratulations! You have purchased the finest automotive subwoofer the industry has to offer. Installed correctly, the ProSeries subwoofers will offer unprecedented performance for many years to come. Warning This manual explains only the basic installation of the subwoofersnot the techniques required to perform the installation. If you do not have the experience that these procedures require, we strongly suggest you consult your Boston Acoustics dealer about professional installation.
Enclosure Recommendations
The ProSeries and Competitor Series subwoofers are designed to deliver optimum performance in small sealed enclosures. The Generator Series subwoofers are designed for either sealed or ported enclosures. The following are the recommended enclosure volumes: ProSeries

Calculating your enclosure volume:
Internal dimensions Height (inches) x Width (inches) x Depth (inches) = Gross Internal Volume (cubic inches)
Gross Internal Volume (cubic inches) 1728 or: Height (cm) x Width (cm) x Depth (cm) 1000
= Gross Internal Volume (cubic feet)
= Gross Internal Volume (liters)
Conversion Formulas 1" = 2.54cm 1ft3 = 28.32 liters 1ft3 = 1,728in3
Remember to account for material thickness when determining external dimensions.

Building an Enclosure

Use at least 34-inch MDF to build the enclosure (1-inch is preferable). The joints should be liberally glued with carpenters wood glue and screwed together with wood screws and sealed internally with a bead of silicone rubber or hot melt glue. Drill pilot holes to prevent the wood from splitting and tighten the screws as much as possible. Excess glue can be wiped off with a damp sponge or paper towel. Warning It is extremely important to completely seal the enclosure. Even small leaks can have a dramatic effect on subwoofer performance. Look, listen, and test for leaks at all joints, around the subwoofer perimeter, and at the wire entrance location.

Sealant
Locating Subwoofer Enclosure in Vehicle
The placement of the enclosure is one of the most important factors concerning installation. As each vehicles interior acoustics are different, experimentation is the key to optimizing performance. Hatchbacks/Sport Utility Vehicles Locate the enclosure in a rear corner for maximum output. Experiment with the subwoofers placement. Hatchback Installation
Warning Make sure the enclosure is securely mounted in such a way as to not shift or fly forward in the event of an accident or sudden stop.
Sedans Provide as clear a path as possible into the cabin by venting through a folded-down arm rest, venting through the rear deck, or venting through an unused speaker opening in the rear deck. Keep any restrictive materials such as wood, hard plastic or metal from directly blocking the subwoofer. Sedan Installation

We provide Theile/Small Parameters for those interested in studying subwoofers further. We do not recommend you use computer software to determine enclosure sizes or type. While highend enclosure design software may be useful for engineering purposes, it cannot completely predict performance in a given vehicle and should not replace a real enclosure that has been tested and listened to in a car. Please use our recommended enclosures for optimum performance. 10

Honey, I shrunk the hi-fi.
The unique shape of Duo-i plus is one key to its exceptional performance. Left and right full-range speakers are isolated from each other in separate acoustic chambers for rich, distinct stereo sound. Another key is proprietary BassTrac audio processing for clean bass at all listening levels. The two technologies work together to deliver stunningly realistic reproduction of your favorite music in any genre, anywhere.
What it means to be from Boston.
First and foremost, Boston is an engineering company, and every Boston system is optimized to meet the highest performance standards (our own). Of course, performance is only one measure of value. So were careful to build all our products with strict attention to everything from the choice of materials to the details of fit and finish. Its how weve been exceeding the expectations of serious listeners for nearly thirty years.
