I hace 2 CVR 12's and the linkn below shows a box i tried to design using this tool. Will this enclosure work for everyday listening and some lower end frequency songs such as bassotronics and bass mechanic? i'm gonna use 3/4 HDF[its cheaper] and liquid nails with drywall screws that are predrilled. about 900 rms total beween the subs.

Will this work and sound clean?
do i need to put braces in it and if so where?
thanks for helpin a noob.

my workable area is 39x16.5x16 [up to 22 inches if abslolutely needed]

I could use MDF if it is deemed more appropriate for this enclosure [bump]

That should be decent for those subs. You should brace from red to black and red to purple. I would also brace from top to bottom towards the right side of the enclosure as well.

so far all i've heard is "decent" and "ok"...

What could i do to improve it? i'm very new to making boxes[this will be my first[and if all goes well my last]] box to make. I'm open to all opinions EXCEPT "leave it to the experts". Im relatively broke since i'm a student and am trying to not pay someone to cut some wood and put it together. Should i fiberglass seal the inside? use a different wood? different box design?

i'm hoping to get lots of opinions so i can see what works and what doesn't.

yes i can get a sheet of HDF from a lumber store. and no its not low quality, they just buy it in masive amounts. for some reason their HDF is cheaper than MDF. i figured why not get the high density.

and last time i checked, almost half of moes plans aren't working, such as the ones about 4 cubes.

You need to bump up the xmax number to get more port area. Normally around
12^2 per cubic foot of box, so around 48^2. Something like this:

Also use MDF and wood glue, not liquid nails. Should be nice when it's done...

Is HDF just horrible or something? i thought it would be better since it is more dense. i've gt no problem paying an extra $3 for MDF but i was under the impression that HDF was better. am i totally wrong?
