the speakers are 6 month old already broke inI've been keeping track of progress on my Focal Grande EM since the day they arrived. Weekdays they play from 7:15 AM until 6:30 and several hours with movies on the weekend it's taken seven months to accumulate 1487 hours.
Focal suggest break in is 1500 hours or more. My speakers have continued to improve, mostly at first but important changes to deep bass and driver integration occurred as recently as a few weeks ago.
Unless you keep a written record day by day, it's easy to think you are done.
