Suggestions for 'filling the port' of bass reflex


I've been demo'ing a pair of full range/single driver speakers for a few weeks and have now gone back to my floorstanders that have a port for the mid-bass and bass drivers...well, it's a little overwhelming now and I'd like to tone it down a little.

Suggestions for what to use....besides a sock?

Thanks, L'wood

Want a bit less bass pull loudspeaker out from wall or corner. Why mess up the tuning your designer choise. And if you think its wrong sell the loudspeaker.
Lots of good suggestions so far.

On a more humorous note, one of the recommendations of stuffing the ports on the previously very successful Radio Shack monitors with Linnaeum tweeters was to use tampons. The obvious side joke was that the speakers caused one's ears to bleed.
I've tried some loose bonded dacron like Rodman suggested and it did work...eliminated some of the bloom. Thank you for the suggestion...had to order it on ebay cos HomeDepot and such had no idea what I'm talking about
Fabric and upholstery shops generally carry the stuff, as it's used in pillows, quilts, etc. Glad that it worked for you. Happy listening!
How large is the hole and how small do you want to make it. I can get you some armafex I use for pipe insolation in differant thicknesses and differant center hole sizes or you can order some on the internet. Type in google, armaflex pipe insolation. It only comes in 6 foot lengths though. Thickness will determin cost. You can also try Home depot for small sizes.
