So would it be accurate to say that it's about moving air? A ported sub has the ports for moving air, the passive radiators are used instead of ports to move air. Where does that put the sealed subs?

All but one of the DefTech subs have passive radiators. Klipsch, Polk, Boston Acoustics, Sunfire are all manufacturing passive radiator subs as their main product line of subs. Is it because you have more control over the tuning?

I would think that a passive radiator would provide a little more than a port would with respect to sound because it is another cone, although not active.

As far as Outlaw goes, I don't see them getting into the "who can build the biggest sub" fever that seems to be the rage with all of the other internet direct companies. Just how many of those can you sell? Why not play on the field with the mass market guy's, all of their subs start around $1500.00. Outlaw can definitely build a unit far superior at a much more competitive price and it would sync really well with their LCR speakers which are sealed.

Unless of course, sealed trumps them both.
