I see you used one bung for maximum extension. Wouldn't using both bungs to run it sealed have provided a greater maximum extension?

Just wondering, because I currently have the DSP version of this sub in my front room and with both bungs in place, room gain is resulting in a response pretty much flat to 15Hz.
