With proper placement, you will get double the output(5-6 db), and a much smoother response. How do you ensure proper placement? Measure your room. Without doing that, its a crapshoot. How do you measure your room?
Download REW(free) onto, preferably, an HDMI laptop. Purchase umik-1 mic. Buy a long HDMI cable, long enough to go from your laptop to your AVR. Measure your subs and adjust placement, phase, gain, delay, etc to get the smoothest frequency response possible before applying any EQ(such as Audysey). If you do not have capable subwoofer eq capability, included with some AVR's, you can get a miniDSP. This will be the largest improvement anyone is likely to ever make for the quality of bass in your system.
One sub, two subs with no eq, two subs with eq(the FR you see of the single PB2000 was basically the same for the three subs I have had...PB2000, XS30, and XV15se) Dual subs filled the horrible null in the FR but left peaks. Eq pulls the peaks down, and I put in about a 5 dB house curve to make the bottom end hit harder for movies at moderate volume.
