Recently, I read that this center speaker is tuned to 70Hz as read on Audioholics.com. Furthermore, my matching towers are tuned to 50Hz. I had been using 80Hz all around. I made the change after my receiver’s room correction software co-signed on my findings. I’m glad I did. The sound is very, very nice. The center is dead simple.
