View Full Version : Box Dimensions?

Hey all first timer here,

I just got an infinity kappa 12" dual voice coil sub, and i know i want a sealed enclosure to save some space and for tonal reasons. So what do u guys think would be good dimensions for my box? I want the ability to run close to 300RMS, but I doubt that I will use that much often. I want the option of versatility, but my biggest thing is clarity. If there's anything else that you guys need to know, then please tell me.


Oh yeah: Infinity recomends a box of 1 cu ft, including the driver displacement. I don't know how much space the driver displaces, which is why I turn to you guys for some assistance.

And how thick should the board be?
And do the actual dimensions matter or is it just the cubic feet?

Good info thanks

Based on that I have decided to make a larger box, but due to the dimension constraints of my car I would like to make a box that sits on the bottom of my trunk, in order to acheive a larger inner volume. However to do this the box goes from a box to some wierd figure I dont know the name for. The dimensions of the bottom surface are 27" x 12". And the dimensions of the top surface are 31" x 12". The box is 11" high. Using these dimension I calculated a volume of 1.58 cu ft.

Is this box ok?
Will it be impossible to make?
Is it high enough for the speaker, sound-wise? (Mounting depth: 6.5")

It will be like that, but you basically had the idea.

Now, being the person that I am, I just figured out a much easier way to make the box. Howerer, I would lose 0.12 cu ft. How big would the loss in sound quality be? Or should I just do it the hard way?

Alright, thanks for everything.
