Out of those, the PB-10 will probably serve you the best. My former room was 19x20 with a high vaulted ceiling and open to the kitchen as well, and I owned the VTF-2 and PB-10 at the same time. Neither was able to fully activate a room that large, but the PB-10 never showed any signs of struggling even with the lowest stuff compared to the VTF-2. That is not to say the VTF-2 isn't a good sub, it is a very good sub though not for a large room - it was fine higher up, but it couldn't handle the lowest stuff without a bit of port noise - the Mk3 might be a better choice as it is a 12" sub.
