View Full Version : Enclosure Frequency
08-30-2011, 06:52 PM
Perhaps this is a dumb question, I'm not sure, I am just looking for the answer. How can I calculate the frequency of a enclosure that I already have?
My enclosure specs:
cu Ft: 2.7 (1.35 each)
It is a dual 10 box. I don't know the proper terminology but both sub sections have an L port that is central yet divided?

Any help would be greatly appreciated

Youre going to need to get the port area of each side, and somehow get the length of the L. Using that information you can plug it in here (http://www.carstereo.com/help/Articles.cfm?id=31) at the bottom calculator. You won't be able to plug in the length itself, but you can type in different frequencies until the length matches what you measured. Make sure you select "square" port and leave slot port set to "no".

When measuring the length on a slot port, it is important to measure down the middle then add 1/2 of the port width for an end correction factor. This gives you total port length.

I just ordered it, so I haven't recieved it yet. I'll measure it when it arrives and see what I can figure out. He said it's 32-35htz? Honestly, I'm very new to car audio. I have a lot to learn. Thanks guys
