Page 2 NEW MIDRANGE DRIVER The most important reason for the improved sonic performance of the CS3.7 is its new midrange driver. This driver was developed to solve two problems that otherwise exist in midrange performance – diaphragm resonances and tweeter interference. Before explaining the new solutions I will review the problems that have been addressed by the new design.
