The inside dimentions are actually 12"x12"x4.75 = 648 sq. in. which is almost exactly 0.4 cu ft. Each speaker has its own box which I have on either side of the trunk. The working volume is slightly less of course because the speaker is in the box.
I am thinking of mounting the speaker externally to the box (i.e. backwards - so that the magnet is out in the open). An article by Graham Maynard on sub-bass equalization suggested this mounting configuration. He wrote that
"when used singly, loudspeakers that are intended for sub-bass
reproduction actually run more cleanly if they are externally mounted
onto an already constructed cabinet. This is because air flow through a
tapered magnet vent is better able to cool the voice coil. As a bonus,
harmonics that develop at the center of the cone are less able to
radiate directly. It is as if the crossover has an additional pole at
no extra cost" (Audio Express. March 2002: 38-47).
I am going to try this setup and see how it works. First I need to get a better quality sub amp though - any recommendations? I was thinking of a kenwood.
Aaron, what do you use for a x-over for your subs? My current amp has a built-in x-over, so I can't use an equalizer with this unit, which is what I would like to do.
