| Re: Dual PB10-NSD or one PB12-NSD/2
The key when mixing two different subs is to match the tuning points and also calibrate them so they reach their respective limits at the same time. There would be no sense in calibrating the NSD/2 and the PB10-NSD to the same level because the PB10 would be compressing when the NSD/2 was still coasting.
Dual PB12-NSD will have similar output as the Plus/2 (20 Hz tune) down to about 30 Hz. Below 30 Hz the dual NSD start to assert an advantage due to their combined enclosure volume advantage. The NSD is also tuned to about 18 Hz vs. ~21 Hz for the Plus/2 (20 Hz tune), so the dual NSD have a large advantage at 16 Hz.
The Plus/2 is going away because it has similar overall output capability as the PB13U and essentially creates redundancy in the line-up. If we introduce another dual driver subwoofer, it will likely be an Ultra and not a Plus.
