could i just bring the back wall up to the white line... my grandpa said it would be no problem...

They're right, that needs to be corrected.

OT - pics of girl holding measuring tape? //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

You may as well just extend the port so that is is the same width all around. Just make sure you don't make it too long/short.

Try it out, throw the sub in there and see what it sounds like.

a: make port longer...

b: make box shorter...

what will sound better?

make new box the right way. Not trying to be a dick, but that would be best, however, If you want to try, change the port. Make your box look exactly like the picture you provided.

that box seems way bigger than 2.5 cubes. A lot bigger, like twice that.

what is the displacement for a se12?

I figured (guessed) like .15cuft.

From your diagram (re's) that enclosure is like 4.2 cubes net. that's after sub and port. and tuned lower than 30hz

well since it is a rough 4.2, and the port width needs to be the same on the side and the back, wouldn't making the depth (23.5 to ~15) of the box shorter solve the port problem and the cuft problem?

just a thought, i respect you decision to make a new one, but my grandpa bought the wood for me and hauled it... and basically did the majority of the work for me... i already told him we need to make the back closer to the port and he said fine... i sure would hate to tell him we need to start over...

basically, if i did move the back in... then it would follow nearly the same specs as the other 12" box specs on the re site... (36" x 15" x 13.5") @ 35hz... i wouldn't mind a little more spl...

what do you think?

Roughly I figure to get 35hz with those dimensions the enclosure will end up being 2.3 ft^3 with a port of 12x3x33 that's assuming the sub displaces .15ft^3

That's about .8 ft^3 of port area...

thats good right? not too much spl, and decent sq considering the driver... im going to go ahead and move the back... take in mind i do not know much about this stuff so if you'd advise me not to do it then nows the time...

thanks for your help man...
