In the KH Series, Wharfedale has carefully engineered the “crossover region” to produce a phase-consistent and linear response. This gives the KH series a pure, natural sound with unbelievable clarity…especially for live vocals (Karaoke). The KH also has a much higher than average sensitivity. This means, that for every Watt of music power fed into them, they are louder and more dynamic. This is combined with advanced overload protection to ensure that your speakers are powerful enough for even the loudest reproduction.
