The other thing you can slap a couple 15 & 18" drivers on those boxes
and you have some serious diy subs lol.
I actually just built a SUB box out of MDF...
For these balloon boxes I only used 1/8" Masonite and Pine wood. I needed to be able to carry it
I could not imagine how heavy they would be with 3/4" MDF. They were 4 feet tall and 4 feet long
The subwoofer box I made it 24" deep by 24" wide by 42" tall. That is about 14 cubic feet before the port and speaker.
The port will be 21.75" x 4" (24" wide minus 3/4" each side+ 3/4" brace down center) and run the full width and depth almost. It will be about 38" long - (24" deep minus 4" = 20" + go down about another 18" to get me to about 38" or whatever exact I need for a 20hz tune)
I figured the port would take up 38"x22.5"x4" [3.16666' x 1.875' x .3333' ] or 1.979 cubic feet.
Minus the woofer puts me around 12 cubic feet I'm guessing- I'll look closer at it when I get to the port length to get it exact.
I plan to drop the two 15" in this weekend actually. I already have dual 12" and they are more than wifey likes until I get my dedicated theater built. Then I will probably go at least quad 15" to go with my DIY speakers. Planning a 12" Woofer and SEOS DNA360 tweeter build pretty soon.
Something like those ^
I had a thread a while back in the DIY sound forum
where the guys were kind enough to teach my how to use port tuning software and design a box and tune it. Now I am hooked. I'd already be knee deep into it if it was not for the twins derailing my home theater plans
We actually had a remodel planned soon but that project is now on hold.
Later in 2014 hopefully I can find a way to resume. I can't wait.
