April 1, 200916 yr so if it is recommended for 2.8-4.0 and you go say 6.0 cubes won't that make you're sub have to much excursion and sound sloppy?excursion in a box is power dependent. The 6 cube box will take less power to reach the same excursion as the 4 cube box. It's also not a given that the 6 cubic foot box will sound sloppy or have poor transient response.
April 2, 200916 yr well shouldn't everyone build to teh the manufactors specs regardless?i see what you mean by building multiple ported box's to see what you like yourself, everyone's views are different. but in my circumstance, any suggestions how i can narrow it down. basically what does each variable change in the result.such as:what happens if i have a 3" x 8" (for example, i really have no idea what a typical slot size is) slotted vs a 4" x 6" slot?what is the difference between a circular port and slotted port (i'm sure this is answered multiple times. i haven't checked but it's just another example)that kind of thing. if anyone has a link to something like this, like a FAQ, i would really appreciate it!Check out www.the12volt.com there is a lot of useful information and a lot of calculators that will help in your design process
April 2, 200916 yr personally, if you have a wall that is over 2ft and there is currently no bracing there and you are gonna be running some big power in there, i would use 5\8" - 3\4" all thread.If the box can be built out of the car and then installed and needs all-thread, i'd run all the runs next to each other then weld the sucker at all intersections. Lock-tite the threads through the wood, use nylon washers, etc everything you can to make that enclosure as hard as concrete.It's not as necessary with less pressure.
