If you want to experiment, go to a fabric shop and buy some Bonded Dacron(polyester batting). You can then control the vent function, by varying the amount of Dacron(tight or loose wrap/longer shorter roll) in the tube. 1" to 1 1/2" thick works great and most places sell it by the yard(cheap).
Does Plugging Bass Port Affect Pace, Rhythm and Timing?
Hi, I recently purchased a used pair of Monitor Audio Silver S1 bookshelf speakers for, well, my bookshelf. :\ As expected, the presentation is a little muddy, and the highs not as extended as they might be otherwise on these speakers known for the quality of their tweeters. I am about to try plugging the ports to see if any improvement could be had. I was wondering if there is any downside to plugging the ports on a bass reflex design as far as bass accuracy and speed.
