MEASURING downfiring ported TW3 build! How does it sound?

A downfiring ported subwoofer enclosure can free up space for cargo since you can set things on top of the box, and also have great low end output due to being ported. How did the JL Audio TW3 perform in the box that I just finished building? Let's do a listening test and measure the performance!
