I thought the 1200 watts of the PB 4000 with a bigger driver, would be more impact than one 3.3 with turbo.. I just watched the Atmos 4k track of John Wick again yesterday, and whatever the sledgehammer sound freq is, I want more of that, hitting harder. Does this help?

I can't imagine needing that damn much, do I?
The second post I am quoting may be the reason for the confusion. It appeared to several posters that you would be able to keep your VTF-3 MK3, and spend $1500 to add something else. In that case, you would have been able to add two more HSU's to augment what you already have. As for needing that much subwoofer, you are asking that question on the wrong forum. Many people can imagine needing that much, and more, in a larger than 4000^3 room.
If you do not have $1500 to spend, and your budget if you keep the MK3, would only allow you to add a single 15" HSU subwoofer, then I agree with something that Darth said earlier. It is almost always better to start with the single largest and best subwoofer that you can afford. I looked up the measured test results for the MK3, and they were not as impressive as I would have expected. But, I also didn't realize that the subwoofer was tested back in 2007. Subwoofers have come a long way since then. Here are the Audioholics test results:
A single PB4000 will be much
better than the MK3, at every frequency, and you would notice the most difference in the lower frequencies. The sledgehammer strikes, in the John Wick
movie, have both mid and low-bass frequencies, but I think it's the lower bass that you really want more of. Meanwhile, your MBM could continue to provide you with some of the mid-bass chest punch you like. That would especially be the case if you put it directly behind your listening position, close to the seat back, and elevated it on something to get it up closer to chest height. Having the MBM firing right into your back can be a cool sensation, if you really like mid-bass.
Alternatively, you could sell your MK3 and buy two of the less expensive VTF-3 MK5's for almost the same $1500. (It would be about $1700.) Two of those subs would outperform a single PB4000. So, that would still be a viable option. But, I still like the idea of starting with the largest (and lowest-frequency) sub that you can, and adding a second identical large sub when you can. That way you end-up with a superior audio system long-term. In any event, you do have two good choices available to you for about $1500.
