I think the important thing is if your speakers will play as loud as YOU want while still sounding good. I listen at levels between 70db and the low 80s, so it doesn't matter to me if my speakers fall apart at 100db. Someone who listens to rock music at concert levels will feel differently.
How much is "LOUD" still a reference point for some?
Do you feel that with speakers things are about the same as they were in the 1970s? In the early days of Magnepan, Advent, Dahlquist and more, much of the competition was in speakers that sounded like a Jukebox and played LOUD. Has this changed or is "LOUD" still the point of reference for many?
