 There is not much difference. And that is an intentional design goal.
They use the same driver and amp. The PB12-NSD is tuned a couple of Hz lower, while the 20-39PCi may be capable of a dB or two more output, but you are unlikely to be conscious of either in a real world situation. |
I've actually talked to Ed Mullen numerous times about the 20-39 PCi and PB12-NSD. The PB12 is both tuned a bit lower AND produces a little more output across its entire frequency response. The two subs do perform similarly, but Ed's recommendation to me was along the lines of "if you have the space, the PB12-NSD will give you a bit more performance for your $599".
