When it comes to subs, the questions are
1) How low?
2) How loud?
Question One is about the octave below 30Hz. The bass that you feel rather than hear. If you want it, you will need a bigger sub than these small cubes that DT makes. Prosubs and the 8-inch Supercubes simply do not have significant output below 30Hz, no matter what the specs say.
Personally, I choose to avoid sub-30Hz bass. I had open-heart surgery a year ago, and bass that low gives me physical pain now. I got rid of my 15-inch sub and now have two smaller ones, a 10-inch Emotiva and a SC2000. This gives me punchy, room-filling bass without making my chest feel like it's being kicked.
But especially for HT, the impact of that 20-30Hz LFE in movies like Prometheus is a value in itself, and either it's there or it's not.
Question Two is about whether your sub(s) can deliver enough sound pressure, which at low frequencies is a function of room size as well as power and driver radiating area. My system has two subs not just to help smooth room modes, but also because the back of the listening area is open to another room, whose cubic volume will dissipate low-frequency sound pressure if it's not high enough.
Understand your needs in the context of these iquestions, and you'll know your next move. I will say this much: Incremental upgrades are more often unsatisfactory than major ones. Most of the time, any given audio component is not operating to its full limits anyway. So a slightly better unit will sound pretty much the same, also not operating to its capacity. Most of the bass in most programs is able to be reproduced at modest levels by almost any sub. A slightly better sub won't change that.
Upgrading is about expanding capabilities at the limits. It's not worth doing unless it's something you will notice. The PM1000 and PC2000 are significantly better performers than the entry speakers you have now -- although they, too, have their limits (mostly in their performace in larger rooms, as you would expect). The PS1000 is a fine sub, and it will increase your overall level capabilities and bass extension, but not in a way that will change the overall character of the low end of your system. (The 1000/2000 performance at 80-100Hz and overall bigger sound will do more of that.)
DT subs are designed to be small and light and easy to reposition. They trade deep bass, efficiency (they need a lot of power), and low cost to get that. If you're willing to accept a bigger and heavier sub, you can get deeper bass for less money from one of the better Internet-direct brands. If DT's benefits are what you want, they do small subs very well, IMO.
