the CEA-2010 measurements presented here are taken at 2 meters outdoor groundplane and are "rms" not peak values. This is equivalent roughly to a 1 meter anechoic (free space) SPL measurement.
The indoor SPL levels are considered to be a corner loaded subwoofer which puts the sub in 1 meter 1/8th space which adds +18dB over a 1m anechoic (free space) measurement. We are considering the listening distance from the subwoofer as being roughly 4 meters in most cases which drops the spl by 12dB (18-12= +6dB at this point.) A peak SPL report of the same signal reported via an rms calculation method will produce about 3dB higher numbers. (Add 3+6= +9dB) So that is why we are adding 9dB to the reported CEA-2010 numbers to compare them with the indoor peak SPL numbers required.
Note that if a sub just barely misses in one frequency band by a single dB or less, for example falling short by 0.7dB at 31.5Hz only, we will go ahead and give it the benefit of the doubt as long as it meets the other criteria since it is a drastic 6dB drop back to the next smaller room size.
I'm sorry but now I'm a little confused on this issue as well.
From what I understand, the sb12 scored a raw score of 96.3db at 25hz. From there, are you adding in the +12db from putting it in the corner as well as adjusting it +6dB for the conversion?
Is its total score 102.3 or 104.3?
