Behringer Nekkst K8 Active 8" Studio Monitor (Single) The 150-Watt Behringer Nekkst K8 Active 8" Studio Monitor (Single)’s unparalleled, world-class performance is the result of a major collaboration between BEHRINGER audio engineers and loudspeaker master-designer/founder of KRK – 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 8? glass-fiber woofer and 1? silk-dome tweeter. K8’s long-throw woofer generates deep, tight bass and virtually smear-proof mids, while the ultra-high resolution tweeter provides sparkling highs – all enhanced by Keith’s Advanced Waveguide Technology for an extremely generous sweet spot.
