5 cuft for 2 Fi Q 12's

[Joe X]

the total net volume includes the 45 corners ?

The two corners in compression chamber airspace are 0.026 cubic feet, and are rounded off since have no effect on performance.

ok I will go for it .. thanks a lot for help !!!

the only problem which I have is that I dont really have a good place to make all cuts etc so I will just go to home depot and they will cut it for me ..

I might have some problems with cutting the port in the front pieces and the circles but I will go for it anyways ...

any advises or anythin I should be careful about ?

big thanks to Joe X for the box design !!!!!

One mote question, whats the size of 45s?

2 1/2" wide.

The one in the port turn depends on if you slant the inner corner (as shown) or not, that 45 has to be made in a way that the port width is preserved (4 1/8") at the turn.

Let me know any other questions.

Front to Back = 16 5/8 x 14 1/2

Extension = 13 x 14 1/2

length of the port include the 45 corners ? or I need to add 3/4" for the 45?

edit;

16 5/8 with the 45

or 16 5/8 + 3/4 = 17 3/8 ?

No, the length of the port parts are final and the 45s do not alter tuning in any significant way. The one in the port turn MUST be made in a way that the port width stays the same, take a look:

If the port narrows at the turn then the whole box performance can be compromised. If you can't do those cuts right is better not to do any 45s at all.

I just wanna make sure, before I start doin anythin.. It doesnt look so complicated .. (i think)

and yea i know that the port has to have 4 1/8 everywhere ..
