Enclosure construction
Use at least 3/4 inch MDF (medium density fibreboard) or Birch ply to construct your enclosure.
It is recommend that the panels are glued, screwed and braced with sections of the same material
you have used to build the enclosure from. The BlackAir woofer is capable of producing internal pressures that can literally bl ow
apart badly made enclosures, so great care needs to be taken with the construction and bracing of your enclosure. It is also
worth sealing the joints with a silicone sealer once the glue has dried to make a perfect airtight seal.
NOTE- Do not screw the Subwoofer into the enclosure within 24 hours of applying silicone sealer to the joints.
The gases given off as the silicone cures can perish the surround of the Subwoofer causing a non warranty failure.
Enclosure Volume
To work out the volume required for your enclosure please refer to recommended enclosure volumes specified for your
Subwoofer. These are listed in cubic feet. To convert cubic feet to litres multiply the cubic feet by 28.3. If you use this formula
calculating your enclosure size will be easy .1 cubic foot is expressed as 12” x 12” x 12” = 1728 cubic inches
