I don't have any experience with the PB2000, but I do have a lot of experience with the PC2000, which will have identical performance to the PB2000. The VTF2 and PC2000 are terrific subwoofers. You will be happy with either one. The VTF2 has more mid bass power and the PC2000 has more deep bass power. You might also consider the VTF3 mk5 which is a beast that will match the deep bass performance of the PC2000 and far exceed the mid bass performance of the VTF2.
