View Full Version : Need help on my odd shaped box.

Hey guys.. decided to go with a different sound so I decided to see what the hype is all about the new Type R's. Anyway, since I want to port two Type R 12's with a small oddly shaped trunk, I created this oddly shapped box plan. I used a box creater, but I dont think its right.

I want to do a slot port tuned to 33 hrtz. I need to know how long to make the port with say.. a 4-4.5 inch port. The depth of the box can be adjusted. Can anyone help me with this odd box?

1.73278 cubic feet for the wedge style part and 4.85352 cubes for the box style part.

Actually the box part is 6.509

And we need the height of the other peice against the box part ;)

eeeek forgot about that...

And I added in the max of 16 inches... I actualy figured in a different number for the depth of the box.

16 inches high

Well hmmmm. Can anyone give me an idea to where I can find out my problem for myself?

Did some adding and my Net volume is 6.52... so if I want to tune it to 32 hrtz that would be 4 inches wide and 15.5 tall at 70 square inches of port?

Here is a better revised version of my box, Instead of the wedge box having a height of 16, I want to go with 15.5 and the cube box being a max of 16, but 14 would be nice
