The NS-IW470WH features a high quality crossover network to ensure maximum sound performance. The crossover circuit is designed to minimize distortion and prevent the deterioration of transients as they pass through the network. You can swivel the tweeter and midrange driver to aim the high frequency sound toward the main listening area. To do this, simply press on the edge of the tweeter or midrange and set the position. You can also adjust the level of the midrange by using the High-Level control to match your taste or the installation environment.
