Do the Damping factors, Bass Extension controls work with the vented solution?
The extension controls still work for the setting above the tuning frequency. For instance, if one tunes the box to 20 Hz, the usable settings are 20hz and 28hz. Setting extension to 14hz in a box tuned to 20hz does not extend the frequency because the low end extension of vented box is mainly determined by the tuning frequency. The extension filter cannot undo that.
