Zuki,
download winisd pro. plug in the #'s and it will tell you what size box to make. How did the other project work out? Subwoofer wasn't' it? Ron

the person who is using the driver has them in a door of infinity 35.
claims the speaker does not go low enough in the bass. i have found when ib installing. some drivers actually end up with too low of a resonance freq. causing the speaker to sound weak in upper bass range. so i was wondering what size box this driver required to best performance, i hate converting litres to cubic feet.
