With push-pull you are looking at -3db so actually 87db/w.
The 12s are 93db/w and 8 ohms, 23Hz. So sealed p-p gives around 90db/watt.
The big rb Sub is an old design but IIRC is about 90db/w, 8 ohms, and ran happily off a 100 watt amp with hard use.
Its partner will use a newish Canton 26cm woofer which is 3.5 ohms and 91db/w, and can handle 100watts. Similar box size and port.
I'm hoping that the Rbs will get down to their Fbs without needing heaps of power and that's why I will use the HK 870 for them.
