    KO70 1. INTRODUCTION The K-array Ko40 and Ko70 are self-powered, Sub Bass speaker systems. They are best suited for high-power extended bass response applications in arenas, theatres, concert halls, churches, and outdoor events. The 21” speakers employ neodymium magnets and 6” voice coils driven by powerful D-class amplifiers. The large ports are designed toa be fully symmetrical to the speakers, which means the back loading on the drivers is consistent and even with no port air turbulence.
  • Page 5 KO70 It is important that loudspeaker systems are used in a safe manner. Avoiding Hearing Damage. Professional loudspeakers are capable of producing extremely high sound levels and should be used carefully. Never stand close to loudspeakers driven at high volume. Set the volume to a safe level.

  • Page 8: Amplifier

    Before applying AC to any K-array self-powered speaker, be sure that the voltage potential difference between neutral and earth ground is less than 5 VAC.

  • Page 9: Rear Panel

    For best performance, voltage drops should not exceed 10% at 115V or 5% at 230V. The minimum electrical service amperage required by a K-array loudspeakers system is the sum of their maximum continuous RMS current. We recommend allowing an additional 30% above the minimum amperage to prevent peak voltage drops at the service entry.
