Possible box alignments:

  • 1 cubic foot sealed for f3 of 40Hz and f6 of 30Hz. A little bass boost on the amp and you have a sealed box subwoofer.
  • Your normal vented box alignments would have too long a port in too small a box. A modified extended bass shelf could be used as 2.5 cubic feet with a 3" diameter vent by 12" long for f3 of 21Hz.
