I have a smaller apt set up, something like 13x17, and the size of the PB16s forces me to place them up front, on the inside of my front speakers. That's where I had the Hsu before too, but I have it near field now, next to the couch. I have been using the combination of REW and Dirac to dial in the subs in the current and past configurations, and have been able to achieve decent results with a flat response curve. The apps in the SVS apps have been extremely helpful in getting the PB16s to play well together, but it did take a long time.
I think the Hsu just works better for my particular room, especially in that midrange area I mentioned. The SVS delivers just as much or even more SPL in that area, but the quality of that sound just isn't as impactful. I attribute this to the specific port tuning of each sub. SVS absolutely crushes, especially in larger rooms. It also comes down to preferences. Some people prefer massive room pressurization, others tight, musical, accurate chest slam. I'm trying to achieve both, but the key is proper placement, timing, correction, and treatment, which I'm still trying to figure out and experiment with. Adding more subs just complicates the issue.
So I know that probably even one PB16 can do everything I want, maybe even just one Hsu. But I just can't get it to do that and obtain a smooth, flat response at every listening position. And I like that having multiple subs allows each one to work much less to achieve satisfying SPL, across multiple positions.
