If you seal the ports on the VTF15h, you will get rid of the group delay that accompanies ports. However, you would lose a ton of low frequency output. In my opinion, it isn't a worthwhile trade. Even when running ported, the Hsu will likely have very good control over the group delay anyway, this isn't going to be a sloppy sub. However, if you are in an apartment or duplex, a sealed option might be a good feature because deeper bass has an easier time traveling through walls. I don't think even sealed it would quite have the definition of the Rythmik though. In my own comparison, I didn't find the Rythmik to be more musical than the Hsu, Outlaw, or Elemental Designs brands, in fact I could not tell the difference in any music recording. What I found, counter intuitively, is it brought more definition to the kind of bass movies use in natural effects. They are more complex bass sounds and the Rythmik caught them better. It wasn't a huge difference though, but it was there.
