4 dc audio LVL 12

[coloradoguy]

I have a question? I am running 4 LVL 5 12s. I know the average room for a lvl 5 12 is about 2 cubes of airspace. I need 8 cubic feet for the box. What is a good box designer program. How do I go about incoperating the port into that 8 cubes

I use a combination of Torres box calculator and winISD for my designs. There are write ups on both programs (and both are free) on this forum, so do a little searching and you'll find those write ups.

Start in torres figuring out the dimensions you want and can use, then input the net volume, tuning frequency, port size, power applied, and filters into winISD to receive your output plot for that enclosure. You'll probably have to input the woofer parameters into winISD before you start.
