Not sure about the specs. But a ported enclosure for that small space, I'm calling some kind bs. Unless it's tuned for only one kind of sub. For the price I'll pass.

Then again I'm super happy with a generic 10" sub box I got online for $30, .75 cubic feet makes any sub sound good. 3 seconds to remove if need be.

It's your call. If you want a custom one look at the top brands JL or Kicker and something else might have some for around the same price.
