All of the subs I listed are sealed and not ported...

Yes, but some are too expensive.

it is just like walking into an Audio Store and asking what they have for $600.  You know they will start at $1k...   Always good to know what is out there for your budget and some others for some more $$$

Just throwing it out there... what about getting two of these? Can't tell if they're sealed or ported, though. Seems like a ridiculously low price...

I haven't heard them myself but Hsu subs have been on my list for a while.

Their VTF series also has an interesting design - they have two ports - and you can leave both open, close one, or close both and make it a sealed sub. The sub is designed to work in all these configurations. The VTF-1 sells for about $460.
