The new 2nd Wave in IN-8 and IN-5 features the latest technology developed by Kali. A new amplifier platform realizes a 12 dB reduction in self noise vs. the original IN-8, lower distortion, higher output, and better reliability. 12 dB reduction in amplifier self noise means IN-Series monitors are dead quiet when not being used. The only noise you'll hear is whatever you're playing in your mix. Natural finish driver cones allows for less material on the cone and increases driver efficiency. Improved cabinet construction helps for better cosmetic longevity.
