Hello to all of autosound and voice pressure lovers. I am from Ukraine, that in Europe. Noticed that many of you had Power Acoustik FUBAR 12Ē. Please, prompt me, help to build a box for him vented. I very ask, you have more experience, I know that loud speaker not very much good, but on greater I do not have a money.
The instruction is not aviable, cubic feet I donít know what is.

Is the space you're working with big or small?


Can you give us the measurements of the area you have to work with?

around 40 hz like it was already calculated is good, and you see it says option 1, and option 2 on that page, option one you put the size and frequency.
