Clio testing:  smoothing is 1/6 octave
For sake of comparison, this is the 1 meter on axis response of the Energy C-2 speaker.  This speaker occupied the exact same test location  and the same amplifier settings as were used just minutes later with Ashley's speaker.
This plot shows the response from the resistive vent on the speaker's back.  Note that the scale now displays 20 Hz to 20kHz (otherwise you'd see little effect).  The mike was placed about 1 inch from the vent.
This final plot shows the mike at 1 inch from the front port of the Energy C-2 speaker.
