SUBWOOFER INSTALLATION AND WIRING DIRECTIONS
Enclosure Materials
Typically, 5/8” or 3/4” MDF (Medium Density Fiber Board) is best for most applications. 3/4” MDF is recommended.
Enclosure Build Materials Connecting joints need to be glued and screwed to ensure no air escapes and joints do not separate under high pressure. Mitered and rabbit joints also help to ensure the enclosure joints are secure.
Bracing
Internal bracing is also recommended to prevent flexing and to strengthen the enclosure. Note: The volume taken up by the bracing should be added to the total enclosure interior volume. There are two common bracing methods.
1. Corner Bracing: These help prevent the connection joints from separating under heavy vibration and air pressure. Use 1’ x 1” MDF at all interior joints
2. Diagonal Bracing: These internal braces connect the top side to the bottom side as well front side to back side. This prevents the wood from bowing or pushing outwards. Use 1” x 2” with 1” surface contact that is glued and screwed.
Wiring
Wiring Parallel, Series or Parallel/Series will affect the final impedance at the amp and great care must taken to ensure the amp is not driven below it’s intended impedance capabilities.
