View Full Version : Box Freq.

I have a box that is 5.5 after displacement. It has 8 2" ports that are 11.5 long. Could anyone tell me what the freq on this would be? It seems like it might be fairly low. Any help would be great.

30.7 hz

Yeah, I got around 31Hz.

30.751 Hz ;)

Thanks for the help. By the way I only have one 12" in it pushin around 200 watts. It seems pretty loud for only 200 watts. What would it be if i put 2 more ports of the same size in the box? Or should i take out all the small ones and make one big square port?

With 10 2" ports that are 11.5" long the tuning would be around 34.4Hz

If you have port noise, I would consider making one big square port.
