For movies I'd like it turned up a bit more. But then it can't handle certain scenes. Like the tyrannosaur coming out of the paddock in jurassic park. So I put it at a level that can handle the more extreme scenes in movies, and leave it at that.

Does this mean that the only drawback for PB-4000 in sealed mode
compared to SB-4000 is the size of the cabinet?
If the cabinet size is not an issue PB-4000 is always better pick?
At the moment I have PB10-NSD, but since I've moved to new bigger appartment I need something louder.
I'm torn between PB-4000 and SB16-Ultra. The price in Europe is 300€ lower for PB-4000 - PB-4000 is 2500€ / SB16-Ultra 2800€.
The size of the cabinet is not an issue, but I'm not allowed to watch movies too loud.
- The listening room is ~32 m2 (~3000 cubic feet), but half-open to other parts of the appartment.
- Music / movies ratio is 80 / 20.
- Main speakers (Triangle Iconor / Extan) are very efficient - 92dB/W/m (one of the good aspects of Triangle loudspeakers) and mid-bass is quite good, so for the music I would say that subwoofer is not needed above 50 Hz - speakers have 3x 6,5" mid-bass driver (<250 Hz) + 6,5" mid driver (250-6000Hz).
If PB-4000 can "simulate" SB-4000 in sealed mode - is PB-4000 better choice for me than SB16-Ultra?
If the thread starter doesn't mind, I will try to kill two birds with one stone and just do a single post. Sometimes, people don't buy quite the right subwoofer for their personal requirements and preferences. That's actually pretty easy to do, as we can't always predict exactly what we need until we get a particular subwoofer in our room to try it. But, the PB4000 will exceed the SB4000 from about 50Hz down (giving up very little above 50Hz) and it will sound virtually identical doing it. It will just play much
louder, at lower frequencies, than the SB4000 will. At some frequencies, one PB4000 will produce as much SPL as two or even three SB4000's.
Of course, there is a significant difference in size. Post 28211 on page 941 of the SVS owners' thread puts the size difference in perspective. (These are 16 Ultra's, but the relative size difference will be about the same for the 4000's.)
In addition to the difference in cabinet size, the ports enable the PB4000 to produce much greater SPL at low-frequencies than the smaller sealed sub can. It is exactly what someone needs for the Tyrannosaurus Rex scene that was mentioned. The larger ported sub will also produce relatively much greater tactile energy than the sealed sub will, due to the additional particle velocity created by air moving through the ports. That tactile response is part of what makes that particular scene so cool.
The fact that we can use different settings with different amounts of bass boost for movies and music means that the PB4000 can easily handle both. If I wanted more low-frequency SPL, I would definitely get the PB4000. And, for the OP, SVS's trade-in policy makes that dead easy. I know that Ed will help you if you decide that you want to do that.
For Delija, I would definitely recommend the PB4000 over the SB16. You can always turn down the volume on a more powerful subwoofer. But, as the OP has discovered, there are limitations to what you can do with a sub that isn't quite powerful enough. And, the PB4000 will be significantly more powerful than the SB16, with all of the same features.
