Speaking about the differences in the freq curves between the M3 and the M50s strikes a chord here in my room.
When we had a nice non-sucky smaller room in the old house, the M3s did a great job. In this larger house they just begged for replacement with M50s. In this larger sucky room the M50s bested the M3s in every area but total enjoyment. "Something" was missing. I could hear it specifically during pans from the M50s to the M3 center. To rid ourselves of the problem I did the unspeakable: I looked at the curves and added a couple db around 80 and the problem went away!!(ok...and a couple more down at 50.....I cross at 60) Now the M50s are a closer match to my beloved M3s!
....yeah....closer, but not exactly the same.
How much is the room, and how much is the speakers??
dunno.
.......I do know that after listening to the M50s with the Christmas decorations up, I have been very slow this year to take them down!! I just gotta make some permanent decorating changes!!
