    The EX6 is a 2-way high output, active, compact, full-range speaker system. Design objectives for the EX6 were focused on the expansion of KV2 Audio's primary philosophy of speakers systems with increased dynamic range, very high output and a consistent sound character no matter what the output level. The EX6 sets new levels of performance for compact cabinets achieved through the integration of new amplifier, transducer and electronic control technologies that are closely tied to a passion for taking performance to the next level.
  • Page 5 EX6 · Overview Acoustic Components KV2 Audio has developed a revolutionary woofer technology called Trans-Coil™. The woofer has two coils, a standard voice coilassembly and a second coil placed directly onthe neodymium magnetic circuit's pole piece.This technology eliminates voice coil inductance resulting in a flat impedance response above the resonance point and achieves faster transient response through increased force and control of the moving mass.

  • Page 6: Ac Power Requirements

    EX6 · AC Power Requirements AC Power The EX6 uses a PowerCon 3-pole AC main system with locking connectors to prevent accidental disconnection. The main AC connector (blue) serves as the power input. The EX6 operates in either 115V or 230V modes. Althoug pre-configured at the factory, the unit's operating voltage mode can bechanged in the field.
  • Page 7 EX6 · AC Power Requirements Current Requirements Each EX6 requires approximately 2.5 Amps max at 115V AC for proper operation. This allows up to six EX6's to be powered from one 15 A breaker at 115V and up to twelve EX6's at 230V. The EX6 presents a dynamic load to the AC mains, which causes the amount of current to fluctuate depending on quiet or loud operating levels.

    This very defined phase accuracy comes into play when trying to stack the speakers. It is very important not to use KV2 Audio Mid-High boxes directly side by side. (Fig. A) This will produce a poor quality sound cancelling out perfectly, which reduces overall output. Defined by the way our ears work, their position on our heads and the brain's understanding of the signals they produce, each ear will hear two sources in the horizontal plane very close together, but very slightly misaligned in arrival time.
