Design and build your own using the manufacturers recommended specs. It'll be really easy if you decide on a sealed enclosure, but ported isn't much harder. There are plenty of online calculators to help you with the ported design. Do a little reading on bcae1.com about enclosures. The RE enclosure calculator is a good tool for simple slot port enclosures, but make sure you double check all the calculations from that program by hand because it's known to be a little off at times. If you have the tools to build your own but can't figure out the design from the info here, PM me and I'll give you a little more specific help.
Really its a matter of preference and what you are looking to accomplish. Sealed takes less space and generally produces a flatter, more balanced frequency range. A properly built and tuned ported enclosure wins in my opinion every time. Build it right and tune it low and you will get deeper lows with more output. All of this greatly hinges on the selection of sub you are using as well. Some do better sealed than ported and vice-versa
kfxnando, why do you prefer the sealed box over the ported? Looking at doing this same thing and am trying to get a nice sounding box to fit tucked away and still sound nice.
well some of my answer have already been posted
so will just add some
sealed boxes keep dust and other rubbish that ends up inside the boxes out
then my biggest reason
sealed boxes are way more forgiving, when it comes to speaker abuse
we go out, get carried away and keep cracking up the volume, distortion happens before the human hear can recognize it, and distortion is not good for speaker.
When overpowered sealed boxes stop the cones from flapping and self destruction
and to methane tighter sound of the sealed box sounds best, others may differ
if you listen to mainly rap, and want muddy sounding bass that just hits hard, then go ported.
if you listen to rock, metal, etc.. go for the sealed enclosure, as the sound will be tighter and cleaner.
Not to flame, but this is the common myth with everyone who cant design an enclosure. Part of this statement is true such as if you just want to build a square with a hole, chuck a sub in it and go, then sealed is going to sound better.
There is a reason that nearly every high-end home audio sub manufacturer uses ported enclosures. They have gotten a bad rap because people tend to think all ported enclosures will sound the same or dont do their homework before throwing a sub in a box.
I will gaurantee that a properly tuned enclosure will sound just as clean and again (preference) more pleasing to the ear with not just rap, but rock and country as well.
Here's mine. I am in the process of finishing the second box. They sit tucked back and molded to the wheel wells and other parts of the Jeep. Got the idea from Towerdude. Check out his thread (just type stereo build, you should find it.)
As for sealed or ported, its up to you. If you have never built a box before, I would think sealed because you wont have to worry about all the thought that goes into porting a box. If Im right, porting a box has a lot to do with the size of the sub, the air flow, and other variables that should be taken into consideration.
Heres a picture. Ive still got to hide the wiring and mount the amp in the spare tirer carrier. Once I clean everything up, it should look better. I am also going to build smaller boxes for either 2-way speakers or 3-ways, I cant decide. Those speakers are going to sit on the little shelf you can see on the box.
