[QUOTE="Blu84Rex, post: 2578350, member: 573118"] As the topic says I need some help. I don't know poo about building these and tuning and stuff. I want to build a box for my 2 12" type R's where the subs are up and ports are back with a divider in the senter for support and just to have 2 chambers. Something like this. [IMG]http://img29.imageshack.us/img29/1995/29cubes33hz36sqin5xd.png[/IMG] The dimensions are 40"x12"x15" that I have to work with I may have a little more hight if I take out my spair and that may add around 5 in or so but it wouldnt be as wide either. I would like it tuned somewhere around 30-35hz no to worried its seems like a good medium. I just can't figure if I need the areo ports or sloted ports and the length on them. If I need areo ports where do I get them and how much are they? If sloted how do I place them or does it matter. I am not looking to pay (sorry guys) for plans on the box just some help so I can learn it for myself. Thanks for the help. [/QUOTE]
