im building a slot vented enclosure, tuned to 30 Hz. While keeping the volume of the enclosure at 1.5 cuft and adjusting the vent cross sectional area and the length, i see that as the area of the vent decreases, so does the overall vent length. At what point does the area of the vent become to small, because by these calculations you could use a vent with a 1 sqin area at 1.17 in to tune to 30 Hz.

generally, you want to keep the port opening as large as possible, within reason..
the larger the opening, the less chance of port whistle.
