make sure you dont put a driver in there for like 2 weeks if you used caulk to seal the inside...

Sealed enclosure + caulk = acid fumes all up in that woofer.

[mirra540ryder]

i just messured twice and i just got the worst results:( :( my devider is to the right a half inch will that cause any thing???? i messured iwth a belt but still. its about one half to three fourths off... what kinda affect will that have. am i screwed? :( :( :( :(

[VR3]

Honestly...

I doubt for your application you will notice a thing.

[mirra540ryder]

did you mean i wont notice a thing????:eek:

[VR3]

You wont notice anything...

[mirra540ryder]

[jmwest1970]

I don't see any terminal cups. How are you going to get juice to the subs?

Being that you build boxes so often, what would you recomend instead?

[BIZILL]

...waiting a week or two for the 100% silicone caulk to dry/cure.

[ch00dlz]

Yeah, if you're going to wait for that to dry, you might as well spread some fiberglass resin inside of that. Seal up all those corners! You might be hittin so hard that those screws might loosen up. j/k

Yah, where are the ports for the wires? He must have some type of small hole drilled in there to run just the speaker wire through...

[mirra540ryder]

yea for now i just drilled a hole but im ganna put some in later

[Josh]

Resized your pics.

[mirra540ryder]

should i go with a ported box? i kinda want it to be louder. any ideas on how i would make one my self? im thinking making a seald box and then sticking a tube in it right

[ShinAce]

A ported box usually wants to be bigger, then you need to add the port. I don't think you can fit such a beast with two 15's.

For the divider, you can put some polyfill(pillow stuffing) in each chamber. Put about 2 massive handfuls in the big side. Now put a good 4 handfuls in the small chamber. That should balance them out again. In reality, the difference in performanece between the two speakers will be more than that caused by the box.

Why is the divider only fastened on one side, maybe two?

Nice! Good luck
