Bronze Member Username: Velk4425Post Number: 32 Registered: Feb-05 | Greetings all, I've seached far and wide to no avail. http://www.accelerator-pedal.com/l-ported-box.htm I used the above web site to design a box. I have a question though. It asks specifically for NET volume. I'm using an Image Dynamics IDMAX12D2 v.3 On Image Dynamics website it suggests a ported GROSS volume of 2.3 ft^3 tuned to 28 hz. How exactly do I get net volume? I want to make sure I have the correct value before I start building a box. The subwoofers displacement is .12 ft^3. Any help would be appreciated, Eric |
