Box specs and airspace for 8 inch subwoofers


<span>Regardless of your wattage rating on your sub woofer, sub woofers</span> differ in only one way. You get an "Open Air" and a "Closed air" <span>Sub woofer</span>, That being said, you'll have to check on your magnet which one you have, to make the boxes for that particular sub woofer. If it is an "Open air" <span>Sub woofer</span>, you should see a hole with "wire mesh" or "metal grid" in the center, at the back of the magnet. If it is a "Closed air", the magnet will be solid with no hole whatsoever.<br /><br />If it is a "Open air" sub, your boxes should always be sealed with silicone sealant, and no ports are to be cut in your box.<br /><br />Regarding the "Closed air" <span>sub woofers</span>, you should have 2 ports cot in the corners of the boxes just below your sub on the face of the box, and the port sizes should be around 50mm in diameter. Get yourself some 50mm PVC drain piping to use as ports. Firstlycut yourself a 100mm piece and insert flush with the front of the box. Test your sound. then try a 150mm piecs and test again. You should start with a 100mm long piece in the one box and add 50mm increments to "tune" the port up to 250mm, depending on the frequency of bass you require. Carry on testing the sound on each increment until you find the sound you want, Then silicone the port to the box for permanent fixing.<br /><br />On a 15 inch <span>Sub woofer</span> ranging between 80Hz and 100Hz, the ample box size required should be a box of 9 inches high, x 9 inches wide, x 9 inches deep. Or 400mm high, x 400mm wide, x 400mm deep. <br />Enjoy! <br />

L7 15 not sounding right.how do I wire the sub in a ported box


It's quite simple, positive from amp to positive of speaker, negative to negative. Make sure it's getting sub frequencies only and not full spectrum signal. Next (if everything checks out so far) see if the box dimensions and ports are correct for your sub. The sub and box combo will have lots of factors when considering tuning of the box and port size. You can find all sorts of info on the website for your sub. Qtas, max excursion etc etc etc. They might even list a few total volume and port dimension sizes for the sub you have and your taste in music. It's quite a science to get it right. More than buying a sub and buying/building a box to get great performance. When you get it right though... music to your ears (and chest)

What puts out more power when subs are ran in series or parrelall


Depends on your amp, ohm rating of your sub, box dimensions and ports or chamber size, size of vehical.
Run the subs in 2 ohm if the subs and the amp can handle the demand. Look for the Qtas of the sub. You'll loose 1/2 of the control to stop the sub if you run it in two ohm. You'll blow the works up if any part of this equation isn't up to the task of a 2 ohm load.
If your budget, space allows, run it in 4 ohms at the max RMS of the lessor (sub and or amp) and add more amps for more subs for more effect. A very well designed box/enclosure with an average component list can make a wonderful sound. It will usually beat a bigger budget sub/amp setup in a generic box. Theres lots of science that goes into a great sound. Dig into it and have fun

Trying to put ported reccomended subs in sealed box.


Well, 1.6 cubic foot for a 15 is not nearly enough. A ported box for 1 15 should be in atleast 3 cubes by itself. I suggest building a new box yourself or getting someone else to do it for you. If factory specs on those subs is no larger than 3 cubes per sub then I'd get the box built to 3 cubes per sub after all displacement and tune it in the upper 30's range. Putting big subs like that in a small sealed enclosure can and will damage a sub. and if you try to port an enclosure that is too small to begin with that will also hurt the woofer. Do it right or learn the hard way.

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.

Box dimensions for 15 in cerwin vega


do you want the box ported or unported (holes or no holes) if you don't got a lot of room than you dont want a ported box. keep in mind the box has to have the correct amount of cubic air space or you could seize your sub... if you're building it make sure you use OSB board (oriented strand board) or MDF board(medium density fiber) your sub needs .7cubic feet of air space in an unported box

What is the sealed and ported box volumes for the audiobahn dub 200 subs?


If you can access the inside of the sub box by removing the speaker, you may be able to measure the 3 dimension of each side of the enclosure.  1 cubic foot is 12x12x12 inches cubed.  That is 1728 cubic inches per cubic foot.  If you measure the inside dimensions of one of the enclosure sides as 10x14x8 inches, then that is 1120.  1120 divided by 1728 is 0.648 cubic feet.  Alternatively, you could estimate the volumes of each side of the box by measure the outside, figuring out where the box divider board is, subtracting the width of the boards used to make and then calculate.  Otherwise, I do not know the enclosure that that sub comes in.  Good luck.  Let us know how it goes.

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.
