That suggests that all good hi-fi speakers have the same tonality. I suspect that there is as much subjective variation in speakers as headphones.
Yes it is true speakers vary a lot, I guess I should have clarified I'm talking about speakers that have the least deviation from flat when measured correctly in a well treated listening room. Now whether or not that subjectively sounds good to the listener is a whole other story, to my ears it does. Also, most good speakers tend to have less dips and spikes than headphones, in general not always.
