OWC254 / OWC304 SUBWOOFER INSTALLATION 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.
