This is a really interesting thread, and because of my technical ignorance I don't have anything factual to add; but my own experience after having owned almost 20 pairs is that while I have enjoyed the sound of a good sealed box speaker, I think that in comparison to a good ported speaker, like the Spendor SP100, or my present Klipsch Epic CF- 4, the bass of the sealed enclosure doesn't "breathe" in the same way. It sounds a little too tight, or maybe a little constipated. The way that the ported enclosure releases the bass notes into decay just seems more realistic to me.
Having said that, I know that there are a lot of poor ported designs; and I've owned a couple that sounded hollow and boomy when they hit certain notes. I would also add that I have not heard the best of the current sealed designs like Magico and YG Acoustcs, so I can't speak for what they sound like.
