Is anyone else getting 62 hz for the tuning?

Thats what my calc is getting with 12 sq inches of port, .415 cubes, and 19.25" of port....

[Ku-sama]

I just have an app on my calculator, I dont know how accurate it is. I dont do designs. So its not real important to me, just good for giving estimates on boxes. I know it gets close, so thats all that matters to me.

 

[Ku-sama]

yup.

yeeea.

sealed would be better than that port.

id cut a .5" piece of mdf and fill in the hole. screw it in from the side and silicone\glue it shut.

thats just me.

why not just disassemble the box and tear out the L port????
