New box time!

Ok, for now I have just bought my wood and materials. I should be starting this tomorrow.

One thing has changed, the size of the box. It will now be 14.05 cubic feet after sub displacement (port will be exterior to the box). :) heheh

WOW! Thats one huge box. How did u come up with that final box volume anyways? And what do u mean your port going to be external? Thats a new concept to me.

My exterior dimensions are going to be 25"x46"x29" and the port will be tuned to 48 Hz. The walls will be 1.5" thick too.

The port will be as long as necessary, just outside the box rather than inside taking up airspace. This way the port (in the way I have designed it) will be removeable and interchangeable.

Ok, stuff has changed.

25x43x29
48 Hz

13.061 gross cubic feet
12.83 net cubic feet

port length 2.827"
8.407" x 16.815" (?) square port

In my calculations on bcae1.com, it asks for a port diameter. I decided to go in the 1:2 ratio and use a port that was 6" x 12" and found the hypotenuse to enter in for the port diameter. (13.416407") Now the output of this has a section for square port dimensions. This says 8.407" x 16.815". Which do I build it to? 6x12 or 8.4x16.8? I'm trying to maintain 48Hz.

For the box building calculator I'm using, it's number 110: http://www.bcae1.com and is the one for ported enclosures.

I've also decided against using the port outside now with this complication.

I've now officially scrapped this project. Sad but true. My van broke down today for a good bit (either ignition or fuel pump went out, not sure). So this has talked me out of making this. I'm afraid that if I go ahead and make this huge box, that I'll just have to take it out and sell the turd.

Sorry to hear that Bill. That totally sux!!! I was really looking forward to seeing how the new box would sound and how it would look in the back of the van

So what's the deal with the van? Do you plan on putting the money into fixing it or buying something different?

Well, it was fixed. ~$370 for a new fuel pump. There has been so much that has gone wrong or bad in my van in the last year, that I'm not sure if I want to build the box. I'm keeping the van now that (from less than a year ago) the transmission was rebuilt, water pump went out, fuel pump went out, and finally new suspension parts for the front end. When the water pump went out, a defective one was placed in (not intentionally) and this caused the power steering belt to break twice, THEN they found out it was defective...

Anyway, I am considering picking the project back up a week or two if nothing else goes wrong.

well 370 isnt too bad for a fuel pump considering most jobs u gotta drop the tank. hope to see updates on the new box (if it happens). good luck!
