2012 focus sedan.  

currently running a prefab decent but cheap box ..in its current position metered 138 @ 37hz sealed on the windshield.  fired the box forward today and noticed it wasn't half as loud this tells me my positioning is right for this car.  So my question is do you think this box is working well or should i build a new box different specs i don't compete but i like loud and low this setup is pretty good for a single 10 but i think there is room for improvement would like some opinions/box ideas 

 

my max dimensions are going to be around W x H x D 30x14x27 to easily be able to fit through trunk opening which is a must as it needs to be removable when i DJ Also like to mention i prefer aero ports !!

 

specs are as follows

(W x H x D): 30" x 13-1/2" x 16"

(net. int.): 2.0 cubic feet

1-1/4" Reinforced MDF front baffle

2.0 ft^3 slot-port tuned @ 32Hz

This is one I have started for a buddy 4 12's firing to the top port toward the plate 4.33 cubes@ 32 with 84 inches of square port area I done this for him for materials and a 12 pack..lol but I will not release it to him till every corner is perfect "fine sanding" I have OCD everything has to be perfect!!!

nice box .. not sure what its has to do with my post thought   x4 12's big difference from x1 10"

More less I was showing how he could do a L port design..This was by no means finished but I thought it might help..

so according to this calculator and my torres calculator my current port that of 2.5x12.25 is yielding me about 30" of port area which is well below the minimum of 37.28 according to this website using this subwoofers xmax   http://www.carstereo.com/help2/Articles.cfm?id=31

 

so in trying to reach optimal port area and i would like to keep it tuned low thinking 28-30hz range this is what i have came up with so far ? obv a little over sized for the sub but i am also under powering it 

I also have bass box software but i cant get numbers to match up with that of torres when using a box of the same size ?? cubic feet does not match as well as length of port for desired tuning

But that's not what he asked for at all, please try and help people and dont post just to post man. Save that for the IHOP.

To answer your question earlier about the box yes i would make a new one, it looks like you got it off mobile sound works website. Nice enclosures to be prefab but arent built as well as you think, my box flexed like crazy when i bought one from them. Plus the board is blocked around the edges since the didnt route the wood for the port opening correctly, possibly hurting the output. Box is almost on the small end once you subtract the displacement of the subwoofer away from the boxes volume. So your current enclosure is around 1.83 cubic feet tuned to 33hz, somewhere in that baballpark.

I never used BassBox program before so cant comment on the differences you are getting when using both programs but i use Torres calculator along with many others without problems. Im guessing since they are made by different people they use different codes to get their desired results. Just my .02

Thanks for the .02 I'll take it so looks like new box it is then anyone have input on the box dimensions above basically going with the same design and firing it the same way just adding more depth more port area and lower tuning.. Also plan to upgrade my amp to something that can run 1700 or so at 2ohm

After looking at some response graphs and what not doing some more research I think I have come up with a better box. Same dimensions however 3.25x12 port 40" long giving me 2.38 after port.sub.bracing displacement. And 31hz tuning.

Calculating my prefab box it was tuned to about 35hz all said and done so this new box built properly should make a big difference. Anyone got input on specs ?
