[. . . ] Use 1" thick MDF (medium density fiber board) for the baffle that the Subwoofer mounts in, and 3/4" thick MDF for the rest of the enclosure. Be sure to use wood glue and silicone to ensure your enclosure is sealed properly, as air leaks will affect the performance of your subwoofer. Using the supplied template, trace the appropriate circle and mounting hole pattern for your PrecisionPower subwoofer on the baffle board. Be sure to offset the woofer to one side to leave room for the port in the baffle. (See Diagram) Cut the speaker hole out of the baffle board with a router. Use a guide or template whenever possible for a clean, accurate job; use a jig saw only if a router is not available. Trace the pattern of the appropriate hole needed for the port, then cut the hole out. When installing the port, make sure you have a distance of at least one port diameter from the end of the port to the wall inside the box. Also, round over the inside edge of both ends of the port to cut down on port noise. Place the woofer into the hole which you have cut in the baffle to check the fit. Install the 10-32 T-nuts (supplied) into the 7/32" holes from the backside of the mounting board. Run an appropriate length of wire into the box, leaving enough to comfortably install the wires to the terminals on the woofer before placing the speaker into its mounting hole. Vacuum out any wood shavings and dust from the inside of the enclosure. (Failure to do so may void your warranty. ) Line the enclosure with a polyester fiberfill blanket or fiberglass insulation about 1" thick. Connect the wires to the woofer observing the proper polarity, positive and negative terminals. Strip away the insulation of the wire about a 1/4" and install the wires into the terminal posts. Once the box is complete, it's time to connect the speaker wire coming from the subwoofer enclosure to your amplifier. Check that you use the proper wire for consistent polarity, positive and negative. (Refer to amplifier owner's manual. ) Finally, sit back and enjoy the incredible enhancement your new PrecisionPower subwoofer brings to your audio system. 2. 3. 4. 5. 12. 13. 6 RETURN TO CONTENTS PORTED ENCLOSURE Ported speaker diagram Internal dimensions should be calculated to determine the correct enclosure volume. Be sure to allow for speaker displacement, extra bracing (if used), and port displacement (only the length of the port that is INSIDE the enclosure).
