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

Styrofoam maybe. Could probably pick up some at a craft store and trim it to the proper size.

First choice would be foam (packaging material but cut to shape). Second - crumpled up paper towel. Just remember it may come out if the volume is turned up too high. Third would be womans nylons.

BTW socks worked for me when I had Bic speakers 30 years ago.

I use a rolled up cotton terry wash cloth with good results. It still allows the cabinet to vent, but nowhere near as much.

If you want to, "tone it down a little"; Go to a fabric/upholstery shop and get some (loose-not "felt")bonded dacron(http://cgi.ebay.com/Upholstery-Bonded-Dacron-Quilting-Batting-Padding_W0QQitemZ350220762258QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item518ac8bc92&_trksid=p3286.c0.m14&_trkparms=65%3A12%7C66%3A2%7C39%3A1%7C72%3A1205%7C293%3A1%7C294%3A50). You can experiment with different densities, by rolling it tighter/more loosely, and damp the port to your tastes. Most other suggestions will turn your cabinet into an acoustic suspension design, and completely ruin the system designer's alignment. Have you tried lifting them off the floor and/or moving them away from any corners?
