At 4 inches, the lower midrange driver bridges the gap between the booming woofer and the vocals. This is often the "secret sauce" of the CS-787. Because the woofer handles up to 500Hz, this dedicated cone handles the critical upper-bass/lower-mid region (500Hz to 1.5kHz), ensuring male vocals and cello don't sound muddy. pioneer cs-787
