Just wanted to start a thread for my subwoofer build project.
It is heavily influenced by a build I saw from another forum from 2005.
I purchased a couple of the XMASS 18 drivers by mach 5 audio ($75 each with local pickup).

Here's the Particulars of the drivers:
My project is to integate them into two separate boxes in a stage to go under the screen of my HT.
I want the stage to be stand-on-able for kids, and don't want it too high. I have done some work in sketchup tonight and did some modeling in WinISD to see what I can expect.
Here's the box(es).
I've only finished half... well, because the other side will simply be a mirror of the finished side. I will be raising it up about 4 inches off the floor as it is downfiring.
and here's the graphs
Although I have room to make the boxes bigger on the sides, I don't think I want to go much bigger just because of how unwieldy they'll get to be. I do plan on making speaker stands to raise my towers up more to be in line with the middle of the screen.
If anyone has suggestions, I'm all ears, this is my first sub build, and am getting pretty excited.
I do have one questions as to port location for the ported version. would it affect performance if the port 'empties' to the floor also, or does it need to vent to the front?
