Straws in ports?

So ive noticed that sometimes at high volume and frequencies, my subwoofer has some considerable port noise. ive heard that taping/putting straws in there helps reduce port noise, so im lookin to try that out.

for this, should i stuff as many as i can in there, tape them around the edges of the port, or what? ive got a klipsch rw-12 btw.

thanks for any suggestions you guys can give me. its much appreciated.
