I have had my M40's now for about 3 months. They replaced a 15 year old pair of JVC 3-way speakers that were part of a rack system(remember those). I have put many hrs. on these speakers with all types of music. I really like the clear and crisp sound, but I am finding it hard to get used to the sibilance (hard s's and f's) associated with these speakers. The sibilance is also associated with my VP100 center. On some recordings it is hardly noticeable, while on others it is unbelievable prevalent. It is also there with cable TV. I have read many posts reguarding sibilance with metal drivers, poor recordings and room characteristics. Do any of you feel sibilance to be pronounced in your speakers? Is there anything to be done?
