Sealed boxes will generally losen the air pressure inside, thus slowing down the woofer, thus reproducing a lower frequency. However after a certain point, it will become sloppy uncontrolled, and sound like trash. It all depends what your drivers specs are. Some speakers are suited for Vented enclosures, some are for sealed, and some fall right in between. Look into how enclosures are determined, designed, and built.
"Sealed boxes will generally losen the air pressure inside"
I meant to say;
When a sealed box is made bigger compared to a smaller box, the air presure will loosen.

when your makin a box n you gotta screw the sides together, wont the split? when i was makin my box when i did, it kept on splittin. does this ever happen to anyone else?
Im gunna port the box but wow... the Home Depot near me that i just got some wood from cut wood for me and thats cool and everything, but cut it so when the walls stand up they lean to the side a little so i guess their saw is off. This box probably wont turn out good.
Don't sweat it - happened to all of us b4 . Sometimes sh!t happens & it can't be help -lol . Carpet hides small defects .
If u got all the tools (& skills) like master carpenter Norm Abram on PBS new yankee workshop/this old house - only then stuff just might come out perfect ..lol

The New Yankee Workshop:
"We are going to create a ported enclosure for a JL Audio W6v2 subwoofer. But before we get started, let's take a moment to talk about shop safety. Be sure to read, understand, and follow all the instructions that come with your power tools. Knowing how to use your tools safely will greatly reduce the risk of injury. And remember: there's no more important safety rule than to wear these: safety glasses. So with that in mind, let's get started on today's project." *walks into the shop, which contains more tools than an average 200 person manufacturing company*
Man i love that show , i've learnt so much off it that ppl asked how i figured out how to some stuff . I never used to miss an episode once i was around .
All those home improvement shows on TLC , Discovery & PBS are so beneficial that the principles help when building subwoofer boxes or carpentry in general .
All you really need is a table saw, and a router (for really nice boxes, rabbit jointed) and some time/effort... But I know my first attempts were pretty crappy. Never used carpet though, tried it once, gave up and scrapped the whole idea. Now I paint 'em black. Much easier!
I've heard someone, somewhere mention something about doubling up on the MDF (either in front or back of box - can't remember). What the hell would that do? Something good or something... simply pointless?
I read something about it somewhere too . Its said that doing that will help stiffen up the box considerably & reduce vibration especially if its a very powerful & heavy sub .
Whenever i'm building my next box i wanna try that & i'm also gonna use 1" on the sides as well !
