Triticum Agricolam Posted October 7, 2015 Report Posted October 7, 2015 Changing vent dimensions won't change how things look in the "transfer function magnitude graph. The thing to keep in mind that the TFM graph is relative, so it doesn't matter if it goes below zero, it just shows what the output at that frequency is relative to other frequencies. You do have a pretty big peaky in your output though.

Triticum Agricolam Posted October 7, 2015 Report Posted October 7, 2015 The HDC series are geared more towards getting loud at the expense of smooth response, they have stiff suspensions so peaky response is what you are going to get. Not much you can do about it. "Nothing prevents people from knowing the truth more than the belief they already know it.""Making bass is easy, making music is the hard part."Builds:
