Personally, I wouldn't just jump around with different subwoofers quite yet. I would start by trying to determine what frequencies make you feel chest punch, and then make adjustments accordingly. I mentioned this earlier, but different people may feel chest punch sensations at somewhat different frequencies and volume levels.
Run some sweeps at higher volume levels (85dB and up) to try to determine where you start to feel sympathetic resonance in your chest. That's really what chest punch is: the air-filled cavity of the chest resonating (vibrating) harmonically, with loud percussive sounds at particular frequencies. And, those frequencies will probably be a little different for many of us.
Once you know what frequency range you are really looking for, you can use a miniDSP to add a boost in that range if necessary. And, you might also try adjusting your crossovers to maximize your chest punch, once you know what you are looking for. So, I would start with a miniDSP, and if I really needed to I would even consider adding something like a Behringer B1200D nearfield, behind my chair, to provide even more chest punch than can be provided in the usual way.
Some people just want more of the tactile sensations that others may take for granted that their subs can provide. That is true for low-bass tactile sensations (tactile transducers and BOSS platforms), and it can be true for mid-bass chest punch as well. This thread was mentioned earlier:
But, if a pair of properly calibrated PB3000's aren't able to generate the chest punch sensation for you, it is unlikely that the HSU subs, with similar mid-bass capabilities, will do any better. Just take this whole process systematically. You can always return the PB3000's if you really need to, and I imagine that SVS would even give you a slight extension on the return period if you are still in a serious trial process. Since Ed Mullen has already posted on this thread, he knows that you are trying to make the subs work.
