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

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 is the volume required for a ported box?


If you take the height times the width times depth divided by 1728 will give you box volumes.
you can get a speaker book at radio shack that gives you charts as to a box with a certain amount of cubic volume it will tell you for a 2" port or a 3" port to cut to a certain length for a certain frequency.
the book is called building speaker systems
speakers for your listening pleasure.
the number of the book radio shacks number is
62-1087a.
H x W x D=
answer / 1728= cubic volume.

I am building a custom box for 2 15 inch Kicker L7's. These will go in the trunk of an 04 Impala. Do I need 4 or 5 cubic feet per chamber in a ported box? Also, what size port should I use? and how long? I...


Hello bgl6176,

According to their specs, the L7's will work in a ported enclosure with as little as 3 CuFt and up to 6 CuFt. Usually with ported, bigger is better, so let's use the 5 CuFt per chamber. I'm assuming that you have room for a 10 CuFt box in the trunk? That's a big box? Almost half as big as a medium sized refrigerator. I hope you don't plan on putting your golf bags in there too. For 10.15 CuFt, a box will need to be 36X29X20, allowing 0.15 for the partition, sub, and port displacement.

To tune each chamber to 30Hz, you need a 4" diameter port 4.6" in length. Lots of custom builders use PVC and even ABS pipe for round ports. You can also buy "pretuned" ports from sites like www.partsexpress.com.

You'll have to measure the exact room that you have available and then adjust the dimensions accordingly.

Here's a link to a great site for calculating almost anything in box building and subwoofer related. You can use the old "multiply LxWxD and divide by 1728" and the other formulas too, but here you can plug the figures in and immediately see the results.

Hope this helps.

Setting correct paper size


By trial and error I found that the paper is specified with the width then the lenght of the paper.

Even though the graphics show you that you are printing the image either vertical or horizontal I still wanted to know when I set up my non standard paper size of 24x 6 which was first the width of the paper or the length. I didn't see that in the manual. All our problems should be so small.

Thanx for the reply though
