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.

I believe that you will want to cut the straws to different lengths to break-up the resonance,I would glue the straws together until approximately the same diameter as the port.Happy DIYing.

Capri Sun straws, after cryo treatment work best. Some prefer the hand made straws from Mapleshade.

A better way than do resistive damping like putting straws is to go for proven modern aeroport, which has flares in both sides of the lenght of the port . Port noise or chaffing is reduced significantly. A lot of companies have been using these. Notice those curved opening on the ports? exactly like that but on both sides. PNR has the patent to this , i am aware the computation for port length over the conventional one has a slight variation. Check PNR aeroport.
