Swivel Tweeter and Midrange Driver, High-Level Adjustment

You can swivel the tweeter and midrange driver to " aim" the high frequency sounds toward the main listening position. To do so, simply press on the edge of the tweeter to change the direction it faces. You can also change the high frequency level of the tweeter by using a "High-Level" adjustor to suit the customer's taste or installation environment.

Low Distortion, High Capacity Customized Crossover Network

The NS-IW660 features a customized 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.
