What is the cubic feet needed to build box for audioban 12


You can use this speaker in either a ported or sealed box. A sealed box would be smaller, (sealed box volume: 0.5 to 1.25 cubic feet) the larger the box the more base you will get. With a sealed box your amp has to work double hard as it would in a ported box ( 1.3 to 3.2 cubic feet) You will get close to double the volume in a ported box. Tuning a ported box with the size and length of the port will determine the hertz the speaker will play at.

I Need To Know What Size Box to Build.. To Get The Best Sound Out OF The R 10's


Depending on the amount of speaker that you have, Alpine recommends that you use anywhere from .85 cubic feet to 1.25 cubic feet per subwoofer. This choice will be reflected by the sound of your subwoofers. If you choose to use .85 cubic feet per subwoofer, you will get a tight sound without excessive cone excursion.
However, if you decide to use 1.25 cubic feet per subwoofer, your subwoofers will hit lower notes and be able to handle more power.
These are factors that you, as a listener, will have to bear in mind when choosing a subwoofer enclosure. Regardless, enjoy your speakers!

I want to make my own speaker box for a 12w7 jl


you should be able to get the speaker specifications from JL's website. There will likely be a range of box size, for example 0.75 - 1.1 cubic feet. You have to take into account how much power you are giving them as well. Usually with a stronger amp you can use a smaller box as the backpressure will keep from overexcursion but produce a stronger hit. Bigger box will produce lower notes (to a point). Is your Integra a hatchback? If so then you don't have to worry about taking up too much trunk room with the box. (if you fill half your trunk with a sealed box, it can start to behave like a bandpass enclosure, albeit without a tuned port). Also, use stuffing to get deeper/better response out of a sealed enclosure (unless specs say no). For the size, unless you're a whiz, you'll have to take your best guess. I would stay away from the extremes of the range, or if you get a specific volume then be within .1 cubic feet. Also, remember that the sub takes up some of the volume, so pay attention whether the volume spec includes the subwoofer. You should use 3/4" MDF for the box (minimum), so when figuring dimensions, subtract 1.5" from each side's external measurement to get the inside volume. Typically the width and height are determined by the car, then you calculate the volume to see how deep to make the box. Especially for a sub this badass, put each in it's own chamber, if not its own box. This means if it's in one box, there should be a panel in the middle dividing it into two halves. Seal all your seams/corners with silicone caulk or liquid nails. Use wood glue and small nails along all joints. The wood glue will be stronger than the nails once it's dry.

Jl audio w7 13 subwoofer system 3ohm driver bridge it 2 ch amp


How much is your speaker max wattage?
If it is 750 or below, it can only be used on one channel, either the right or the left.
If speaker can handle 1500 watts then hook the positive speaker wire to R+
Hook black negative speaker wire to L-

Now it is bridged

Trying to find out wat the watts are on a jlw3 12 and a jlw0 12


The JL 12W0 needs 125 watts RMS. Sealed box it needs 1.5 cubic feet. Ported it needs 2.5 cubic feet.
The JL 12W3 needs 300 watts RMS. Sealed box it needs 1.25 cubic feet. Ported it needs 1.75 cubic feet. I wouldn't suggest running these subs together.

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.
