Awesome to hear man, tls guy amd wmax are the best guys around to help you design the box. Im sure you will be please with the driver, i can't wait to get mine up and running (though its the 12.1 not the VQ).
I can show you the design that i had come up with for my sub, it worked out to be 3.9 f^3 with a slot port that was 16'x3' and 54' long. I ended up making all the cuts with just a single sheet of 1" MDF.
Keep posted up on what your thoughts are for the box!
PS: what did you go with for an amp? The external that was recommended, or a plate amp (the BASH one that you were looking at i think?)???
