Pb-2000 pb12-nsd sb2000
I am also thinking about trading up to a pair of PB-2000s. I've owned a pair of PB-1000's for about 4 months now, and I think they are great. However the thought of dual PB-2000 is on my mind. So I posed some questions to Ed over at SVS. I wanted to get his take on the differences between the PB12-NSD, and the new PB-2000, SB-2000 and even the SB13 ultra. Below are my question(s) and Ed's answer.
Me: "Other than power differences in the amplifier section how does the new PB-2000 differ from the PB12-NSD? Both use 12 inch drivers but aren't the drivers basically made of the same material, and play the same? As for the SB-2000 does it really go as low as the PB-1000 which I already own (duals). I don't have any experience with sealed designs. How do these compare to the SB13 Ultra? Any information you can give me is much appreciated."
ED: "Hi Ben -
Compared to the PB12-NSD, the PB-2000 has a different cabinet and finish, a new more powerful amp, and a new driver. In terms of actual performance difference, it has slightly deeper extension and 40% more max output from 25 Hz on-up.
The SB-2000 does indeed extend very deep, but it won't play as loud at the deepest frequencies as a larger ported subwoofer like the PB-1000, PB12-NSD or PB-2000. It's easy to confuse deep extension with max output at the deepest frequencies, but they are two different performance variables.
Dual PB-1000 is a very potent package! The SB13U would outgun a pair of PB-1000 in the mid/upper bass ranges, but would not exceed them in the 18-36 Hz octave (again the physics advantage of the much larger combined cabinet volume and dual 3.5" porting is very hard to beat). If you are looking for an upgrade across the board in terms of dynamic output capability, I recommend a pair of PB-2000. They will extend somewhat deeper and will have almost twice the max output of a pair of PB-1000 at all frequencies from 18-80 Hz."
