I am going to make a list of a few specific areas that I hope the DAM gang will freely comment on as individual areas of performance and the mids and treble are two of them.
WS, I hope we can give you helpful info on your question. When all is said and done, I am sure the whole of both speakers will be greater than the some of their parts and, as always, if a glaring problem exists or shows up as a room interaction, it will get the most attention.
Funny, in life a bad trait, if serious, can destroy a person's repution in the eyes of others regardless of other fine qualities. We focus on that which is most important to us. Too much treble energy-too little treble energy, the person listening next to you may care less. To them, sounstaging is the summa bonum of speaker design.
Of course, I'm the last person to talk to about the break point; I've been married to the same woman for 35 years.
