i was wondering if any one had made their own subwoofer box and if there is a difference in sound?? i'm planning on making mine for my two 12'' subs and was wondering if any one had done it....and if so do you regret not going out and bying a box?

every good enthusiast makes their own box

the plus side is that you can make them exactly to your spec, you can build them to fit your trunk, you can build them to an exact amount of internal volume and if going ported you have an infinite number of possibilities towards port design, tuning, etc.

IMO, building your own is always better, and way more fun. if you have the means to create your own box, then by all means do so, just make sure you have all the right tools and make sure the design is right before you start to build, but that is what we are here for.

If you already have tools and stuff building a box is dirt cheap too. Like $20 for a sheet of 3/4inch mdf. If you know the cuts you ned to make you can even have homedepot cut them for you for practicaly nothing. Then you just have to glue/screw it together. Maybe slap some epoxy in it to seal it nice. I have 2 1.3cube boxes I made to fit the sides of my trunk. The hardest part was getting the angles right on the box since I didn't go for a rectangle box because I wanted to try to squeeze more room outt of my trunk.

I have pictures of my box on the second page of my website at http://www.sounddomain.com/id/tdb30

what size mdf should i use for two 12'' subs? i know different people have preferences but what is standard i guess you can say??? is it the3/4 inch?

3/4" is most commonly used

I'd use at least 1/2", but for a few more pennies, get the 3/4". It'll be more durable and you won't need as much bracing because of it's rigidity (not that the 1/2 inch isn't rigid, but the 3/4 is stiffer.) I've seen them built with 1/2" before, but if you're going to do it, you may as well do it right the first time. If you figure it with internal dimensions, remember to account for the MDF in your measurements.

cool thanks you guys you all have been a big help now i am off to go measure my trunk and see how big i want my box then off to home depot to get mdf......

Dont go by trunk space, I'd go by the optimal operating dimensions for the subs. Just a thought though.

yeah i know that but i also got to account for the space in my trunk

There are a lot of things to keep in mind when building a box. You can essentially tune your subs to the sound you would like to have by building you box to the correct specifications. A sealed box is super easy to build, but I beleive that a ported box allows me to tune a subwoofers output more to how I like it. I have tried both, and I have always liked ported a little better. If space is an issue, then sealed is prolly the way to go.

I would use a box building program like WinIsd to build you box. If you like a box that beats in your chest hard, then you want something on the smaller side...if you want engulfing bass that shakes everything, then you want a bigger box. The former usually has more output in the higher bass frequencies, while the latter will usually promote deeper bass.

You have probably heard my current box, and it is definently on the deeper side. If you want to shake everything, then go bigger (within the subs specifications)...if you want it to be hard to breath, then go a lil smaller.

BTW, if you are building your first box, I would build a sealed. Once you feel comfortable with that, then try ported. Ported is not that much harder for slot ports, but you just have to be a little more precise on the measurements.

...IMO, 3/4 MDF is a good size to go with...and if you want to carpet it (or vinyl), go to an automotive upoltory (sp) store...and not to a car audio shop like Al-and-Ed's that will charge 4 times what it is worth.

I wouldn't go buy MDF yet, you need to first figure out waht kind of box you want (sealed or ported), what size box you want and if you are going ported, what you want the port tuned to. Spend a bit of time creating a design and then build it after you've worked out everything.

Should have thought of that before you bought 2 12s

Make sure you pick up some PL400 to seal the box up. The **** is super strong. Make sure you pre-drill the holes and you should be able to use ordinary drywall screws. MOST likely people at Home Depot don't know what PL400 is, so look near the paint section, for caulking.

hahah guys come on i have already thought about what type of box i wanted, how big i wanted it, and i have spent more then enough time on a design for the box.... i just wanted to know if anyone had built their own and if they regreted it...lol

I don't regret it.

Hmm... did I regret it? Well, I regretted the first one I ever built out of fiberglass. I cut out my skeleton, assembled it, glassed it all up, finished it, painted it, etc. Too bad I forgot to allow for the fiberglass on the outside of the skeleton. Needless to say, it didn't fit. Time wasted, money wasted on product, etc. But, I did learn to measure twice and cut once. LOL. Other than that, I'ev never regretted building a sub box. There's a sense of accomplishment in doing something yourself.
