The SVS 12" subs are relatively low output subwoofers. They do not at all fit the criteria for your listening tastes. The PB2000 will not get much louder than the SB2000, it will just dig a bit deeper. You need a 15" at the very least. I would be looking at a
Hsu VTF3 mk5 or a
Reaction Gamma 18 if you can afford them. They will hit a lot harder than the SVS subs. If you can accommodate a live sound subwoofer
like one of these, that might even be better for you, because these can get very loud.
Your ears are not fine if they were ringing. That is probably tinnitus which is indicative of some noise induced hearing loss. You may be able to undo some of the damage if you give your ears a break from loud sounds for a couple days, there are some mechanisms of recovery if they are not subjected to any more high pressures (ie loud sounds). This can help prevent a temporary threshold shift from turning into a permanent threshold shift. What I mean by that is that your ability to hear quiet sounds lessen, and it might only last a short while or it can be permanent. You do not want to be the guy who goes around saying WHAT WHAT WHAT all the time, which is what you are heading towards. I like loud music too, but I pay attention to noise exposure guidelines, I am trying to save my hearing for future use.
By the way, you might think it hypocritical that I am suggesting you get a louder sub and then warning you about noise induced hearing loss, but hearing is less affected affected by bass frequencies. To be sure, loud bass can cause hearing loss, but it takes more sound pressure at low frequencies. The frequencies you are overdoing it are at treble frequencies, which is easy to see as you are cooking your tweeters. Your hearing is most vulnerable at 3000 to 4000 Hz, which is also a crucial range for understanding speech, so you do want to protect that frequency band.
