Anyone try stuffing their ports?

I had B&W P6s with foam port plug that I used to good effect.

I loosely obstruct the ports of my Dynaudio Contour 1.3mkiis and OHM 100S3 Super Walsh 2s in my wife's sunroom, which is 12X12 with cathedral ceilings in that the speakers are relatively close to the rear walls and the bass can be too much otherwise in there.

My smaller less bass heavy Triangle Titus XS monitors run with ports unobstructed when in that room.

I do not obstruct the ports with the same speakers in my 12X12 office with conventional ceilings directly below the sunroom.

My point being that obstructing ports to various degrees can be an effective tool to help tune a speaker to room better if needed.

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.
