Because I won’t be playing movies crazy loud-would the PC2000s sound similar in terms of the tactile feel and low frequency sounds as compared to PC4000s as long as it wasn’t needed for super loud volume
You have been asking similar questions for quite a while now, and there is really no way for anyone to answer them for you.
You will simply have to try something to determine whether it is enough. But, it is important to recognize that, for many people, overall listening level and subwoofer volume are two entirely different things. That is because we can't hear very low-frequencies as well as those in our normal hearing range. So, we may want to make the subwoofers play louder, than our other speakers do, in order to accentuate the low-bass frequencies more. Your overall volume level might not change, but you might want to crank-up the subs. But, our preferences for bass vary, just as our listening levels do, so no one can really predict how much bass you will like.
I think that based on things you have said, the PC2000's may very well be sufficient for your needs and for your preferences. And, that would still be my starting point, if I were in your shoes. But, there is no way to know that for sure until you try them. Someone else in exactly the same room might prefer the dual PC4000's. They would go lower in frequency and they would be capable of playing those low-frequencies at a louder volume level.
In my opinion, that is the primary advantage of buying larger, more expensive subwoofers. It's not generally more mid-bass we are chasing. It's the frequencies below 30Hz, and below 20Hz that we are usually after. And, that's the place where the PC4000's will have the biggest advantage. They will go lower, louder, and they will be able to produce more low-bass tactile response when they do it. But, will you actually need that much low-bass SPL and TR? I honestly can't say (and no one else can either) whether you will find the additional low-frequency SPL/TR worth the cost difference. There would be a little more low-bass with the PC4000's, even at modest volume levels, but how much would it be worth to you?
I thought that there were some Canadian dealers who would let you try subs on approval. In my opinion, that is the only way you will know for sure, how much subwoofage is enough. If I were me, today, I would buy PC4000's, because I know now that I like a lot of low-bass. If I were you, and didn't know for sure what I liked, I would try two PC2000's, and only move up from there if they failed to satisfy me. I actually did just that--starting with smaller subwoofers, and gradually moving up to larger ones. Of course, I also have a much bigger room, and that also makes a difference. But, none of us ever knows exactly how much will be enough, until he tries a subwoofer (or two) and finds out.
I really hope that helps!
I just don't think you will get to a more definite answer until you actually try the subwoofers in your room.
