I'll say it again, the SB12 is a *great* sub for music and extremely satisfying for HT in a small-medium room. It's at least as good for HT as any other sub in this price and size category.
Why is it so hard you ask. Because being "great for HT" is a function of moving air, and that is a function of driver capability, and power. If you want better, there is only one way to get both HT and music capability, find a sub that has a even more heavy duty driver (have you ever inspected the SVS Plus driver up close? You'll appeciate how much better it is than many of the competition's drivers) and stuff an even larger amp in it. Now we are talking Paradigm Servo 15, JL Audio, or Velodyne DD class subs at least 2X the price. If you want the most awesome 12" single driver small sealed sub, JL F112 can't be beat for sound quality AND awesomeness for HT.
I have heard the Abyss at the dealer and my impression is that it won't do anything the SB can't do already. It seemed to taper off below 25Hz at the same rate that the SB does, and I doubt it does any better at top SPL based on the specs alone. It did sound very very good, but again, no better than the already good SVS. So given that, I'd say that the SVS wins out based on its features, and known build quality.
Yes the PEQ is a pain to use, and only really recommended to be adjusted provided you have some software and time to spend, but it's well worth it if you are actually serious about sound quality. Using that, you can achieve results that allow it to sound better than other subs lacking PEQ until you get to the JL or DD series subs with their more sophisticated EQ's
