Frequency tunning. (1 Viewer)

How do I know at what frequency my sub is tuned to?

Here's what I did:

I ran tests in my sub from 10Hz to 20Hz, because I think that my sub is tunned around those frequencies.

From 10Hz to 13Hz, there was a decent amount of air coming out of the port (like a fan with three settings in the middle position), and the driver's excursion was a lot.

From 14Hz to 17Hz, there was a lot of air coming out of the port (like a fan with three settings in the max postion), and the driver's excursion was a lot also.

From 18Hz to 20Hz, there was a decent amount of air coming out of the port (like a fan with three settings in the middle position) , and the driver's excursion was minimal.

From 25Hz and up, there was almost no air coming out of the port, and the drivers excursion was normal.

It's between 18Hz and 20Hz then.

you could just give us the alignment of the box and the TS prams of the driver.

Allen Ross,

I know the frequency according to the box and driver TS parameters. Just wanted to know the actual tunning. According to what've read, Seth_L is right.

thanks

 

[Allen Ross]

so were the simulations you did correct?

 

[John t.]

yes. the sub is tunned to about 18Hz to 20Hz. In WinISD the tunning was at around 18.5Hz, so I think WinISD is pretty accurate.
