So I think I'm going to get a second PC-2000, but then I started thinking what if I just got 1 PC-4000 instead of a second PC-2000? I'm still in my 45 day return shipping window.
So my choices are:
1. Keep the PC-2000 and add a second one.
2. Return the PC-2000 for free and get a PC-4000.
I don't know if the performance of the PC-4000 is so much better that it's worth keeping just 1 of those for a year or two before upgrading to dual PC-4000s.
That's never an easy decision. I just reviewed the max output of the two subs, for comparison purposes, and to refresh my memory. The big difference between a pair of PC2000's versus a single PC4000 would be in the low-frequency extension. A single PC4000 would have a good bit more SPL, below 20Hz, than a pair of PC2000's. The advantage of the dual PC2000's would be primarily in the opportunity to achieve a smoother frequency response. I don't think you would notice the relatively modest increase in SPL that you might get with dual 2000's at and above 31.5Hz.
If you had a small room--let's say under 2000^3, I might gamble that you would have enough room gain for the dual PC2000's to satisfy you in the <20Hz frequencies. But, at 3000^3, you are into a room size where I believe that low-frequency SPL is more important. So, I would say that it's still a fairly close call. But, if it were my decision, I would go ahead and get the bigger subwoofer now, with a definite plan to add a second PC4000 at some point in the future.
Financially, the upgrade path from one PC4000 to dual PC4000's may also seem less shocking than the upgrade from dual PC2000's to dual PC4000's. I could be mistaken, but I think you will really enjoy the additional low-frequency extension of the PC4000. And, the new features are pretty cool, too. So, I would go with the PC4000.
