Stuffing your port is a fine idea at times.
Speaker designers aren't all knowing or all capable. Your room may present a number of issues which may be solved by having a higher cutoff frequency, or your room aesthetics may force you to place a speaker too close to rear walls, giving you too much bass.
Stuffing the ports also has one additional advantage: It increases the dynamic range by reducing excursion below the port tuning frequency.
