Anyone try stuffing their ports?

If your bass is booming you can improve the sound by blocking the ports on bass reflex speakers. The only speakers I've needed to block the ports on had raw cotton fiber in them (PSB Stratus). I tried the foam from an equipment box I had but it did not give the result I wanted. I looked around but could not find any raw cotton fiber so I went to a fabric store and bought some pillow stuffing fiber which worked very well. Hope this helps. Happy listening.

Years ago I read of someone using plastic straws bundeled and inserted into the port. This seams like an interesting middle road to try. I assume that the straws were cut to the same legnth as the port tube.

I have used plastic drinking straws to fill the ports similar to a method used by Meridian and then ProAc.

Using plastic straws on my Mirage M3's changed nothing until there was a sustained bass note like a pipe organ, for example. The straws then prevented the woofer from oscillating. The improvement in such cases is dramatic. The Reference Recording "Star of Wonder" has such a sustained bass at the beginning of the "Nativity Carol".
