93Works Posted March 19, 2017 Report Posted March 19, 2017 Hey guys how's it going? So I want to build a box and came up with this through Torres Calc, I have no idea what I'm doing so I thought I'd come to you guys for some guidance. It's also my first time using SketchUp, but I built this simple sketch to see how it would turn out. I noticed that the port height is 5.70" in SketchUp but in Torres Cal its set to 5, what did I do wrong? Is there anything else that I should fix?
Triticum Agricolam Posted March 19, 2017 Report Posted March 19, 2017 Looks like you are off to a good start. What sub and amp is this for? What vehicle will it be going in? I'd suggest rotating the port 90 degrees so that it runs the full width across the bottom of the box (so it will be 6" wide). This is more space efficient, easier to build, and it will help brace the box.

I'm building it for a RE Audio 450W RMS 12" SCXv2 Dual 4 Ohm sub powered by a Hifonics HFi1000.1D. It's going in a 99' single cab Ford Ranger. How does this look? I made the box bigger to get is to 1.5 cu fb and fixed the depth as i was off by like .16" for the subs mounting depth. By the way, did I input the correct number of common port walls?
Joe X Posted March 19, 2017 Report Posted March 19, 2017 3 common walls is correct, just keep in mind that since your enclosure is now 8" from 7.5" now your port needs to be 6.5" wide instead of 6" to be a 3 common wall.

Thanks for that, here's a revised version. Does the box look appropriate for the sub that its being built for?
1gggman1 Posted March 21, 2017 Report Posted March 21, 2017 I JUST sold 3 of the SCX 12"... Ran them hard... Good coils... Old style tinsel leads are suspect but these subs pound... I always wanted to try a larger box... Ran them off a HFI 1000.1d in fact for awhile... I never could increase the box due to excessive power... But if all I had was the HFI 1000.1D I believe these subs could really perform in a 1.75 ft3 4" aeroported @ 34 hz (13.8" long) without tryin' to input T/S into a program... I'd say that that amp will be at it's best pushin' those in that box... Just fishin"... but a TON of experience baitin' the hook here... Should be a SOLID setup with that amp... Just a thought... Joe X has a factory box nailed but this is another option... Lots of x-max ... Lets use it!
