The VIKING series is designed for those who truly seek powerful sound. In this line, we have some models that are highlights in major world-level championships. The Viking 8000 offers 8000Wrms in 1 channel at 1 Ohm, used for large projects because it's a high-performance amplifier, with a frequency response of (16Hz - 7kHz) and can be used to power various types of speakers. It also features a 100% aluminum chassis that offers better heat dissipation, resulting in low battery consumption and excellent performance.
