There is kipple measurements online for both the 805s and 126be. I will link them below. It has been a long time since I heard the 805s to comment but I have owned speakers from both brands. The revels tend to be smoother and more dynamic as a whole. You might feel like you are missing some highs with the Harmon curve which is a 5db drop in treble over the entire frequency range (just a downward sloping line).
I can’t speak to near field on revel. I always sat about 10’ from mine. The drivers are superbly integrated
