Ok, someone requested that I post pictures from when I designed a subwoofer box using a computer program... I'll start out with the project.. I had a 1999 Jeep Cherokee Sport, and decided to custom design and build a subwoofer box for my 15" JL W0 subwoofer. Below is a picture of my Jeep... [img]http://www.newnorth.net/~lklncr/sub/jeep1.jpg' alt='' width='1000' height='659' class='attach' /> Here's is an rough design I drafted on my computer...not too technical ;) [img]http://www.newnorth.net/~lklncr/sub/roughdesign.jpg' alt='' width='557' height='348' class='attach' /> I did measurements of my Jeep to find the required dimensions for a custom fit: [img]http://www.newnorth.net/~lklncr/sub/seat.jpg' alt='' width='602' height='342' class='attach' /> I ran the program called UniBox (which can be found at: http://home20.inet.tele.dk/kou/ubmodel.html ), input the parameters of my subwoofer, and basic box requirements. Below is a condensed image of the program output: [img]http://www.newnorth.net/~lklncr/sub/program.jpg' alt='' width='650' height='972' class='attach' /> [img]http://www.newnorth.net/~lklncr/sub/excusion.jpg' alt='' width='952' height='683' class='attach' /> Now onto calculating the other dimensions of the box to meet the calculated volume of the box...

Below is my simple hand drawn layout of a relay that is going to go on a pre-fabbed PCB (printed circuit board) that I purchased at radio shack. [img]http://www.newnorth.net/~lklncr/sub/neon.jpg' alt='' width='259' height='336' class='attach' /> Here are the results: [img]http://www.newnorth.net/~lklncr/sub/subfinal.jpg' alt='' width='1000' height='906' class='attach' /> [img]http://www.newnorth.net/~lklncr/sub/customboxlit.jpg' alt='' width='1024' height='768' class='attach' /> It sounded excellent; hit lows and highs which was my goal for my 15" sub which normally only beats on low frequencies... I could of went a lot more in depth...if you have any questions please feel free to ask. Jesse
