I have 8 alpine dvc type r 12s, should i port them or go with a sealed box.


depends what kind of car they are going in and what kind of sound you are going for.
generally speaking ported boxes are louder, if you choose this i would recommend filling box with poly-fill.
non-ported boxes get deeper bass and hit much harder. no matter what set up you choose a good quality box that does not flex is EXTREMLY IMPORTANT. you will want the wood to be at least 3/4" thick and the correct cubic feet.

Need dimensions for 12' 450watt IMPP Subwoolfers for proper air space


Subwoofers differ in only one way. You get an "Open Air" and a "Closed air" subwoofer, That being said, you'll have to check on your magnet which one you have to make the boxes for that sub. If it is an "Open air" Subwoofer, you should see a "wire mesh" or "grid" in the centre, at the back of the magnet. If it is a "Closed air", the magnet will be solid with no hole whatsoever.

If it is a "Open air" sub, your boxes should be sealed with silicone, and no ports are to be cut in your box.

With "Closed air" subs, you should have 2 ports below your sub and the port sizes should be around 50mm in diameter. You should start with a 100mm long piece in the one box and add 50mm increments to "tune" the port up to 200mm, depending on the frequency of bass you require.

On a 12 inch subwoofer ranging between 80Hz and 120Hz, the box size required should be around 27 liters, meaning that you will end up with a box of 16 inches high, x 16 inches wide, x 16 inches deep. Or 320mm high, x 320mm wide, x 320mm deep.
Enjoy!

Building a box, need to know best dimensions for box and port


Hello dirt_digger6,

The specific sub you are asking about would seem to be the TS-302F which is the only 12" 800W Pioneer I have located.

Directly from Pioneer's support knowledgebase:
TS-W302F = Ported: 2.5 Cu.Ft. F3 = 39HzPort: 4  x 6.5 tuned @ 37 Hz with 12 % port noise.

An enclosure 16X18X21, constructed from 3/4" MDF will yield 2.69 Cu.Ft., allowing .19 Cu.Ft. displacement for the sub and port.
There's an excellent "box calculator" located here on the12v.com web site. You can measure the space you have to put the box and fiddle with the dimensions to get close to your ideal volume. There are also calculators on the12v.com which will allow you to calculate a port length based on port diameter (or width/height), enclosure volume, and desired tuning frequency.

Hope this helps.

Dimension please for enclosure 12w3v2-d2


Typically you use one cubic foot per sub, so a 2 cubic foot box will work fine. To build a basic one, just a rectangular box, using 3/4" MDF (excellent material for a box), cut pieces this way:

2 - 25.5" x 13.5"
2 - 25.5" x 12"
2 - 12" x 12"

This will give you an interior volume of exactly 2 cubic feet. Cut your sub holes out of one of the 25.5" x 13.5" pieces.

Box dimensions


I've Got The Same Subs, I Got A Formula On The Net, Its Dimension Is Aprox 9 D X 24 H x15 W.
Although I Have Them In A Home Made Ported Box I've Made, Its Dimensions Are 8 D X 23 H X 17 W And Its Sound Pretty Damn Good. I Have A 2 Inch Round Port X 6 Inch Long. The Formula Says I Should Have A 3 Inch Long Tube.

Enclosure type


Sealed box and somewhat large if they are 12's I usually try to get 3 cubic feet overall internal dimensions and generally the inside dimensions will be 13" tall 32" wide and 13"-14" inches deep. with no divider and make sure the box is sealed. Personally I like to phase the speakers backwards. Gives the bass a little more rumble.
