My newest box design with 3d image

I am making this box for a school project, and well i decided to go ahead and make a 3d model of it on the computer. I have to admit it helped out in many ways. I found problems, and flaws in the design i had on paper. Granted this software is readily available to everyone, i used SolidWorks, it is cool to see how it can help, even in enclosure designs. Other than the circles, all of the cut outs are goin to be 1/4" acrylic windows. This box is for two 8" subs. Each enclosure is about .92 cu ft. After my experience with designing this box on the computer, i will be using this program for all future box designs.

Please let me know any opinions, comments, or suggestions.

By the way, it took about a total of 3 hours sitting in front of the computer to finish this. Plus there was alot of paper designing and other thoughts.

Also please let me know if anyone has any questions.

The slotos on the outer sides of the box are ports. the ones that are close to the center of the box are going to be windows. Like what you would see on a bandpass box. The top holes are also going to be windows. These will allow you to see inside the box. Each woofer will have its own enclosure. There will be a neon on each side of the box, inside, hidden from view, and will be set to go along with the beat of the music, or i can set them to be on all the time, with an on/ off switch.

And hell, i might sell this one when im done with it. I'll let everyone know when im done, there will be pics of the box, and possibly an asking price if i sell it.

Thanks

Got an update.

I changed a few dimensions to accomodate some new subs. Instead of using really crappy Wal-mart subs, i'm going to use 2 new Rockford Fosgate Punch Stage 1 8" subs.

I now have another question. I plan on carpeting the inside of the box, for a clean looking interior. My question is simply this, if i carpet the inside of the slot ports, is there going to be any annoying port noise / whistling?

first off, carpeting the inside of a port will not change the sound, carpet is not a solid object, sound can go through it and it does not take up hardly any space so it's not going to change tihe dimension of your port,

second, what frequency are you tuning your ports to?? if you tune it to low you'll blow you subs apart. different subs can handle different frequencies, the rockford stage1's are the lowest rockford model and they don' t sound that great vented, why don't you go sealed.  i sell rockford so i am very familiar with their capabilities.  and instead of 2 8's why not 1 10.  you could probably get 1 10 stage  for about the same price as 2 stage1 8's  if not cheaper. 

third, slotted ports, round ports, and square ports all have the same output, there is not one better than the other it just depends you box size and tuning frequency. 

also if anyone needs any boxes built, you can send me the specs that they need to be and i can built it and ship it.  price would be material x 2 + shipping and handling.  MDF is not very expensive so you're not looking at a lot of money, a box for 2 12's would probably cost you around $50
