How do the vents/ports correlate to mic distance? Typically when you mic a
cabinet you are much closer than I was. I used my Zoom H4 to record. It has
a tripod mount. The legs of the tripod pretty much dictated the distance. I
couldn't hold it and play at the same time nor did I feel like spending the
time to do a better job.


At what height have you put your mic?
If you put your mic at the height of the dust cone , your mic can be
24" to 48" of the port , depending of the design of the box. If so ,
the mic catches 60-95% of the driver sound missing all the "low
frequency coming from the bass reflex".
And also there are "sweet spots" when miking at a certain distance.
Maybe the mic was out phase between the driver and the port?


Close miking to "infinite open baffle" is the only way to really hear
what the driver are made of . ( I think! )
