That depends on what you are looking for Sealed or ported the formula to figure our Cub foot size is LxWxH \ 1728 This will produce a number such as .823863896928365489236489623984823748923749 .8 is the cubic foot of the box. U might have to see what you want, Bandpass has deeper smoother bass -=to me=- but cant be heard as far away but sounds better in the car. Sealed will hit harder, sound kind of punchy but will be able to be heard down the block by the 15 year old who will pop your trunk lock in a heartbeat.

Box size and airspace for 10 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 10 inch <span>Sub woofer</span> ranging between 80Hz and 100Hz, the ample box size required should be around 26 liters, meaning that you will end up with a box of 11 inches high, x 11 inches wide, x 11 inches 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

What size box should i build fro two pioneer 12inch speakers 1200watts each


For optimal performance there is really only one size for the box .Firstly, you get two different types of subwoofers, an open air, or closed air sub. If it is an open air sub ( hole with mesh in the center of the magnet) no ports are required, and the box should be sealed on the inside with silicone sealant. If it is a closed air sub ( no hole in the magnet) you need a 50mm port about 120mm long. If it is a 12 inch speaker, the box size will be 13 inches x 13 inches x 13 inches.

Box recomendations


It depends on the size of the subs- 8z 10z 12z 15z? whether or not you port the box is up to you- a ported box is generally louder than a sealed box -as you are coupling and tuning the sound from the rear of the driver with the sound generated from the front of the sub- but the box is also generally larger as well.Then aside from your preference of ported/sealed you have to account for the recommendations of the manufacturer as to whether the sub/speakers are meant to be placed in a ported or sealed enclosure. Most 10 inch subs do well in a box that yields .75 cubic feet to1.0 cubic feet.most 12z do well in 1.0 cu feet to 1.5 subic feet and 15z do well in 1.5 to 2.5 cubic feet. I have a set of 15z that require 4.25 cubic feet per sub-so its important to look into the manufacturers recommendations. The easiest box to make would be a sealed enclosure-and the sound quality generally yields a tighter more accurate bass sound along with increased power handling capability- try going to rockford fosgate .com and look into the woofer box wizard its a program that calculates air space for whatever size box you have room for-hope that helps you-good luck
