my box for the xb I have:
This box is still a work in progress...the skeleton of the box is made up of 1/4" mdf to save some weight...I have 10 layers of 4oz f/g on the back and 9 layers of 4 oz on the top...the next step for me will be making the speaker rings and doing a mock up water displacement test so I can figure out how long I have to make the slot port(im hoping that the box will be about 5.5cuft) then the front of the box will get 10 layers of the 4oz f/g and then I will be adding about 5 more layers to each wall with 18 or 20 oz cloth to reinforce it plus 2 layers on the exterior of the box

 

What speakers you gonna put in it?

 

12" dayton dvcs...the port will be tuned to around 26 or 27hz

 

I havent heard of those you have a link or anything? Click the link on the bottom of my post if you want some ideas.

the nice thing about these is i only have to run a 600w amp to get them to pound...plus the ports air velocity will be about 13m/s so there won't be much port noise at all

 

das a big ol box!

 

1/4'' mdf is not strong, you need at least 3/4''

 

that looks nice. are you going to paint or wrap it?

 

That is why he is reinforcing it with fiberglass.

 

Apparently it's better to do large flat surfaces in MDF because fiberglass is stronger on curves.

 

yes the 1/4" isn't very strong but after all the layers of f/g are done and the internal bracing im doing you'd never know the differance

im going to wrap the box in black carpet to match the stock interior

 

Hows this coming along? You got any more pics?

 

still the same but i did add some bracing in the box thats about it....been working on a full setup in a buddies integra i have about 2 weeks to wait before i have any time to work on the box ill post more as the box gets further
