Ok I built a new box that is about 1.8-1.9 in volume ...

I got cheap and didn't want to put 4 inch piping because it was soo expensive ... I found some 3 inch tubing that i got from Ceran Wrap ..

anyways....

I've made soo many different sizes to change the frequency, yet i DO NOT hear a difference .. I've done 30 hz up to 50 hz ...

Is it because my diameter is too small??
