And... I'm still deciding on PC2000 vs PC4000! I suspect dual 2000's are very reasonable for my current environment, and since I have shared walls, having more SPL or lower extension isn't necessarily the most responsible choice. But I also like the idea of going big now (a 4000) instead of later to save the trouble of upgrades, etc. I think what would settle the matter for me is understanding if gaming even takes advantage of lower frequencies at all? If not, then I have no need. Its hard to say, though, because I haven't found any data. 7.1 has been around for more than a decade on game systems, and Atmos is clawing its way into the gaming scene too. So sophisticated gaming sound is here, but I have no idea of the frequency response the developers are programming into the games. (My focus is on war games, i.e Call of Duty, Battlefield, etc, where explosions, helicopters, etc, are common).
You are very welcome, Rob! I am not a gamer and haven't really been able to find out anything about the low-frequency programming used in them. But, I would expect any special effects involving explosions, helicopters, tanks, artillery fire, etc to benefit from more robust low-frequency SPL and TR. Another factor to consider is the Atmos angle. As more channels are added, the demand on the subwoofers grows. That might also lead you to want more subwoofage in the future. I also suspect that war games are becoming more sophisticated in their effort to simulate more realistic experiences. I would expect that, if war games did not previously have a lot of low-bass, more will be added in the future in order to enhance realism.
I am a little concerned about the shared walls. The lowest bass frequencies travel further, so the PC4000 would increase your opportunity to annoy your neighbors.
And, you are on a suspended wood floor (if you are in a loft) so you should be getting pretty good low-bass TR. But, the flip side of all that is that, if you are hesitating because you do kind of want to try a PC4000, I'm not sure that you won't regret it if you don't go ahead and upgrade.
Part of the reason that most of the people on the various subwoofer threads advise others to go bigger to start with, is that most of us have been through multiple upgrades ourselves. And, I believe that most people upgrade in order to obtain more low-frequency performance, and not simply for more SPL. (Having dual subwoofers for enhanced frequency response is a slightly separate issue from that of upgrading for more performance.)
If you really feel the pull of a PC4000, I think that I would do it if I were you. (I already know
that I would do it if I were myself.
) If necessary, you could always run it in the Standard 20Hz mode, and you would still have a lower frequency response than you do now with your PC2000. That has about a 22Hz port tune. At times, though, you might want to cut loose with the Extended 16Hz mode, and that could be very exciting. I would still plan on eventually adding a second PC4000, but I agree with you that the upgrade path is a little easier if you start with the right model, and then just add a second one when you can.
I hope this helps!
(Note: In most cases, I don't think that it would hurt to do an Audyssey calibration with a sub in the Standard mode, and then at times to run the sub in the Extended mode. I have seen people experiment successfully with that, measuring the FR with REW to determine the effect. What that generally does is to allow more room gain, for a larger low-bass house curve. Since your loft volume is pretty large, I think that might work well when you really want to cut loose.)
