I have an Outlaw sub with the optional port plug and tried it both ways and honestly, I couldn't hear much if any difference.

I too have an Outlaw sub with that port plug option and concur with the above. After numerous tests with and w/o plug the engaged I could not detect any audible difference. Maybe at relatively high SPL levels but for normal listening, no change.
