View Full Version : 2 12" Ported Box Help

12-03-2006, 10:49 PM
I have searched the forums for pictures of boxes that hold 2 12" subs. There are alot of ways to build them, and I was just wondering if one way was better/preferred over the other.

I have made drawings. Click to enlarge

1. Which box style is the best for performance?

2. Is it better to have the 2 subs share air space (1,2,4) or have their own separate chamber (3)?

3. If I were to make a box #1, would I need the red part in box #2?

I've only made a ported box for one singular sub. I don't know much about making a box for 2 subs. Thanks!

Hey, Im interested in this too.

What is the best design, seperate chambers for the subs or in one same chamber, with 1 port?

If designed right the will perform the same.

So there isnt a preference, or neither does better than the other if made correctly?

They should be the same, I always advise single chamber though since there's less to get wrong.
