I ordered an IDMax 12" sub and a Arc Audio 1200w @4 ohms amp!!
So, i've heard that 1.5 is the cubif feet of air volume that is best for the sub. I am gonna use 3/4" MDF to build it. So i just am not sure what the deminsions should be for it. This is my first attempt at a custom box. Oh, yeah i'm using a sealed enclosure!!
I just need some advice as what size the box should be and anything you pros can tell to ad me in my building my box.
Hey Ludestud,
1.3 is a normal size for these subs however 1.5 isn't going to kill 'em in a sealed box, they'll only sound deeper. A sealed box is the way to go and don't forget to add an inner brace. For true performance double walled is the norm with a layer of sound deadener sandwiched in between.

Prepare your future. It wasn't the lack of stones that killed the stone age.
Hey if you need help with the dimensions for your box, there is a handy dandy volume calculator right here at the12volt.com. Just go over to the calculator section and you'll find what you're looking for. I already looked , and if you just want a simple box, you could go 15"x15"x16" with 3/4 mdf and get an interior volume of around 1.63 cu.ft. This leaves you a little extra volume to take up with bracing. The best way is to get a good idea of the volume of your bracing, then come up with your box dimensions as adjusted to that. Keep in mind, your driver basket will take up volume, too. This all depends on how accurate you want to be. I commend you on your choice of a sealed enclosure, especially with all that amplifier power!! Just remember, spending a little extra time on this box will make all the difference. Measure twice and you'll only cut once. Make sure to use the right materials. I like big dog's suggestion, he knows his s***. Make absolutely sure your box is glued up real good. The screws should only be a backup, but dont hold back. Glue and screws! Gluing and bracing are probably the most important construction techniques.Of course, 1" mdf never hurt anyone. ( unless they dropped it on their toes). Do a good job on this first custom box and you'll be hooked. then wait a few years to see if you want to thank us or not. HAVE FUN. that's the point, man.
