(Sens) 84dB 83dB A speaker’s performance is only as good as it’s enclosure. Proper installation, enclosure size and crossover frequency will maximize the overall performance of the subwoofer. To properly design and build an enclosure, knowledge of woodworking as well as the proper tools are required. We highly recommend that you have your enclosure built by an authorized DB Drive retailer. However, if you decide to install it yourself, we have included the parameters of each driver and recommended enclosure sizes. If after reviewing the enclosed information you have any addition questions, please feel free to contact our technical dept. It is difficult to give exact box dimensions that are universal for all cars and trucks. It is for this reason that you must be able to calculate the space in which you have available in order to achieve the proper air volume required. KEEP YOUR SALES RECEIPT Take this time to attach your sales receipt to the manual and put in a safe place. In case of any unforeseen reason this product may need warranty service, your receipt will be necessary to establish purchase date. For detailed warranty information please refer to enclosed warranty card. WARNING! Exposure to high pressure levels can cause hearing loss or damage. Listening to your system at loud levels while driving, will impair your ability to hear traffic sounds and emergency vehicles. Use common sense when listening to your system. While installing your subwoofer enclosure in the vehicle. Securely fasten it to the frame or floorpan. If the enclosure is not secured properly, there is danger of it becoming a projectile in a collision. Due to continuing product improvement, specifications and design are subject to change without notice. CALCULATING ENCLOSURES It is recommended to build your enclosure from 3/ 4” thick MDF (medium density fiberboard). Make sure the enclosure is sealed airtight. Calculating External Volume 1.) To calculate box volume, measure the outside Width x Height x Depth of the enclosure. Example 12” x 14” x 9”=1512 ÷ 1728” Cubic feet 2.) Next you must convert cubic inches into cubic feet. To do this, you must divide the cubic inches total by 1728”. Example 1512 ÷ 1828=.875 Cubic feet Calculating Internal Volume 1.) To calculate the internal (net) volume of the above box you must first multiply the thickness of the wood you are using by Two(2). Example 3/4” x 2= 1.5“ 2.) Next subtract 1.5 from each of the outside measurements of the box. Width Height Depth 12 - 1.5 = 10.5 14 - 1.5 = 12.5 9 - 1.5 = 7.5 3.) Multiple the new totals (H x W x D) Example: 10.5 x 12.5 x 7.5 = .5696 4.) Next you must convert cubic inches into cubic feet. To do this, you must divide the cubic inch total by 1728”. Example 984.375 ÷ 1728=.5696 cubic feet. PT10D2 / PT10D4
