Anyone can help?

This is not a home theater sub question but I am sure someone here would know this.

I was given a car sub box. It looks like a 5th order type made for 2 - 10" subs.

Could anyone here tell me what the cubic inch space is if I gave the DIMMs of this custom box?

I would like to add 2- 10" subs to it, but I need to make sure what the cu inch is before getting some subs to add to it

Thanks and here is the size of the box.

This is all out side DIMMS:

HEIGHT = 16"

WIDTH = 16"

DEPTH = 15 1/4"

PORT AREA WIDTH IS 2 3/4"

The MDF thickness is 3/4"

by my guess it's right at about 2.2 to 2 cubic inch, but I am thinking if I can find 2 - 10" subs that can handle @ least 2 - 2.2 each.

Anyone know?

Here is the box:



Thanks for any help.

You give width, but what is the height and length of the port. What thickness material is used to form the port? Assuming it's a slot port, using one or more walls of the cabinet to form the port itself. Got pictures? Any bracing inside the cabinet?

From there, it's just basic geometry and a little fiddling in WinISD to determine net air volume and actual enclosure tuning.

Hi Brent - I just found out my box is the eD design.

By using the calculator on eD's website and folllowing its measurements, it looks like my box is

2 - 10" 11kv.2 subwoofers

Measurements:

A = 15"
B = 34"
C = 16"

Which its including 2- 10" subs @ tuned hz of 35 (if I get the eD 11kv.2 subwoofers (2 qty)/
Current Interior Volume - Total
2.87 cF - 81.3 L

Makes any sense?

Also - do you think the Acousta-Stuf Polyfill be worth adding into this box?
