The 150-Watt NEKKST K5 Studio MonitorÕs unparalleled, world-class performance is the result of a major collaboration between BEHRINGER audio engineers and loudspeaker master-designer/founder of KRK Ð Keith R. Klawitter. This incredible reference system is ideal for all critical listening environments thanks to the custom-engineered bi-amplification system that features separate amplifiers for the 5" glass-fiber woofer and 1" silk-dome tweeter. K5Õs long-throw woofer generates deep, tight bass and virtually smear-proof mids, while the ultra-high resolution tweeter provides sparkling highs Ð all enhanced by KeithÕs Advanced Waveguide Technology for an extremely generous sweet spot. ¥ Ultra-linear 150-Watt reference-class studio monitor ¥ Designed by renowned acoustic icon Keith Klawitter, founder of KRK* ¥ Advanced Waveguide technology creates ultimate acoustic dispersion and extremely large ''sweet zone'' ¥ True bi-amping mode with 2 separate amplifiers for ultimate sound reproduction ¥ Ultra-high resolution, 1Ó silk dome tweeter for ultimate sound reproduction ¥ Long-throw 5Ó woofer with deformation-resistant glass fiber cone ¥ Adjustable to a wide range of acoustic conditions and subwoofer operation ¥ Separately controlled limiter for low and high-frequency overload protection ¥ Servo-balanced inputs with XLR, TRS and unbalanced RCA connectors ¥ High-density composite enclosure for ultra-low diffraction and reduced low-frequency distortion ¥ ''Planet Earth'' power supply for maximum flexibility (100 - 240 V~), noise-free audio, superior transient response plus low power ¥ Designed and engineered in Germany
