thoughts on switching over to a ported box?

Set up as follows. Would like to hear some input on the ole ported vs sealed...
I've researched some, but I figured I could get some good responses here as well.

A single 12" Kicker CVR124 getting 400 watts @2 ohms from a Polk PA D5000.5
It's currently in a generic sealed box, volume around .9 cubic feet.

I am a bit underwhelmed by the sub's output, and was thinking of switching over to a ported box. It's just not quite loud enough.
I am eyeing a ported box that is roughly 1.8 cubic feet.

Are you set on keeping that sub, or you looking to get a new one? Either way, get a design done and build one from the builders on here, or most will build them for you too. Go ported for sure.

Yes, I am about 90% sure I am keeping this sub, but I am open to explore. For the sake of this post, lets say I will be using that subwoofer.

Do it! You'll notice much more output with a custom ported enclosure. You can get one made pretty cheap right now from pro-rabbit.

Thanks myjaja, checking out that thread right now.

From my experience with cvr's, id say 2.2 cubic feet tuned to 34hz for a 12".

Thanks, I will keep that in mind. Will dimensions be particularly important, or is it more about just getting the correct net cubic feet amount. I would like to avoid an equilateral box that will just up a ton of space.

So it sounds like ported is the way to go. Just curious, how much is my current box .9 cubic ft box limiting my sub's output? How much does size matter, heh.

Ported >> sealed
It's nice to be able to hear your subs.

Smaller box = more output but lower SQ...
Look up what is recommended for the woofer.

Found this from sonicelectronix

Minimum Sealed Box Volume 1.0 cubic feet
Maximum Sealed Box Volume 4.6 cubic feet
Minimum Ported Box Volume 1.75 cubic feet
Maximum Ported Box Volume 2.25 cubic feet

found the owners manual and pulled up this.

I'm nit around my comp. What's the tuning come out to on that sq vented enclosure?

Ended up finding a ported box with a lil over 1.8 cubic feet internal volume, tuned to 34hz. Thanks for the help, you guys rock.

Swapped out the boxes.

:inlove:

It feels like an entirely different set up! I honestly just can't believe it, the change is ridiculous.

Glad you like it man. Wait until you get more power and subs in a box built for them. Wangin yo!
