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.
