LOL. It's up to you how much you really want to spend. Your budget as of two days ago was $350. You've since increased it to $450, and seem willing to go even higher. Of course, the more money you spend, the better the subwoofer you can get. However, I truly do try to be mindful of peoples' budgets. Nothing is more discouraging than to post for help and have everyone say "you need to spend $xxxxx more before you get anything worthwhile." The PB10 and VTF-1 are both capable subs that might do just fine in your room. The A3-300 with upgraded driver should be a noticeable step up in output from those two. I don't know how the PB12-NSD and PC12-NSD compare with the A3-300 - it's possible they are all pretty comparable.
To give you an idea of what your extra ~$170 would get you going from the PB10 to the PB/PC12, I do know that the PB12-NSD enjoys a ~3-4dB output advantage over the PB10. Whether that matters to you depends on your listening levels and room size. 3-4dB is
a significant increase in output. It's not a night and day difference, but it's certainly noticeable.
I can guarantee
you that if you stick around on this forum for any amount of time, you'll end up getting upgradeitis. Going for the bigger one now should help put that off a bit, but it's pretty much inevitable to want to upgrade at some point. Also, it can be cheaper in the long run if you spend a bit more to start with because you'll end up upgrading fewer times. Take it from me - in the past 2 years I've gone from a Velodyne VX-10 to an Infinity PS212 to a single PB10-NSD, added a second PB10-NSD, and finally sold those and got an Epik Castle. In hindsight, it would have saved me a lot of money to "go big" from the get go. I'm not saying you have to do it that way, and it's quite possible you won't get the bass bug quite as badly as I did. It's just worth considering.
Alright, enough rambling. Hope you can make an informed decision. Best of luck, and keep me posted. Feel free to ask any other questions you may have.
