I was wondering what the best frequency would be to tune my box to for one fi bl 12. I currently have it in a box that I made based off of the DD Box Plans. It's 2.5 cubes and I'm not sure what it is tuned to. It doesn't get very loud off of 500 watts, but I'm sure it's because of the box. Getting a bigger amp pretty soon as well.

Do you think a Fi BL would sound better in a box tuned to 30, 32 or 34 hertz?

This is the box I built. . .

fi web site stipulates 1.5-2.5, i would land in the middle and 32hrtz. a little smaller than recommended if you put more than rms,a little larger if less. and yes, that 500 watts is only tickling that voice coil.
