The lowest frequencies will travel the longest distance, so if you are concerned about this, that might be another reason to get a pair of 2000's. The PB/PC 4000's will have more low-frequency SPL than the 2000's, and the 16's will have even more than the 4000's. As noted in my previous post, I believe that dual PB16's might have a little more low-bass SPL than you will need anyway, as you should be getting pretty good room gain under about 20Hz.
As you correctly observed from my previous post, it would be better not to mix two different models in a small room. Two matching models (the shapes don't matter) will make level-matching the volume of the subwoofers much easier.

Just want to be considerate...
Unfortunately, as Mike said, very few things can stop Bass from traveling, just one of those law of physics
My Cats, always go hiding before a storm, since their hearing is very accurate, and know it is coming, before we do.
While I do believe in acoustic/sound proofing, for speakers. Bass Trap can only deal with mid Bass frequencies.
The lower ones will travel a lot, and everything
To me, my personal opinion. Is setting the subs at 20Hz, and not chasing the very low frequencies, and use some TT instead for this purpose;
Shakers - Simple/Cheap Hookup - Visual Guide
And also trying this option;
III-C: Cascading Crossovers:
As a back ground about my-self, I use to be a purist, and still believe to get all the bases done right, for proper calibration.
Getting, the ULF from my subs, created too many problem for my room, as unwanted vibration and rattling
The TT link, I have provide, took care of this problem
Also, after trying the Cascading Crossover link, even the purist in me, did like the results better
And now because of this, I will try increasing my 4 ceiling speakers to an extra 0.5dB, and the rear one to +1dB. Just to see if I like it better, and very close to proper calibration, just a preference thing, for been more excited when watching a movie. And if I do not like the results, I can always switch back.
