Sonotube With 12" Infinity 1250w Driver

[buggers]

Hello everyone. I am interested in buiding the Sonotube, but I have no measureing equipment and don't know what dimensions it should be or what kind of crossover it would need. Can you point Me in the right direction? I would like it to go as low as possible for HT. I already have the driver. Thanks.

I'm not sure this would be an appropriate driver for a HT setup (it's built for autos).
If it's ok (and I really have no idea) can someone tell me if you can use WinISD to calculate the internal value just like a regular box sub? Or is there something with the sonotube that makes it different?
