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 rabbet 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 BRUTUS BRZ SERIES SUBWOOFERS ELECTRICAL BRZ12D4 21504 BRZ12SQD4 Series Series Series 4 4 4 4 0 0534 0 0676 SPL 2 83V Xmax Over Hang Xmech Suspension Watt RMS Watt PEAK
