Clarion’s Z-Enhancer Plus lets you select from three performance patterns — Type1, Type2, and Type3. With a touch of the control keys, you can arrange the high-quality sound to better fit the genre of music you are listening to. While most loudness controls boost bass at 60 / 80 / 100 / 200Hz, the Magna Bass EX circuit boosts bass around 50 Hz. This creates a rich, deep, defined bass rather than the muddy, booming bass of a standard loudness control. The Magna Bass EX boost levels are dependent on the system volume, which results in balanced system response and dynamic bass reproduction.
