Not quite. I think regarding the 'pulse' it became pretty much clear, it's a personal thing. Some say it's a belief, some say it was imagination arcing from fancy pictures in magazines to a personal listening experience, but nobody still claims that there were explanatory models based on science (except psychology, maybe).
Regarding 'flat', it depends. If it was an original recording from the farther past, one would prefer a speaker that resembles the original monitor back in the day. If it was a remastered version, one might prefer a more contemporary speaker. In the first case the 'flat' is ruled out even for the 'flat FR' guy. The speaker has always to match the recording, not a standard. Having a standard means, one same speaker type for all recordings, that's all so convenient!
Same, basically, with the 'pulse'. But its hard to grasp. Because the industry is lying at You deliberately, as to keep You a) unsatisfied and b) confused. Are You?
