Here is my new box that I started this week. I went with ported, I am going to do something similar to that Navigator.

E, I have a question. How much is that plexi side going to cost you. I called some places today and the best I could do was $164 for two 10.75 x 32.25 for the top and bottom (but when the box is turned woofer side down it will be the sides). That is very expensive. There is a place called selectproducts.com and they have 16x32 3/4 plexi for $59 but I would have to cut it. I would be looking at $140 & I would cut or $164 to have my exact measurments cut.
Oh yeah, I finally got the 12W6V2 specs for a bandpass box today (I emailed JL tech support)so that is also an option, but I would have to build another box, but it's fun so I don't mind.
