The K20 is the strongest model in the flagship K Series and probably the world’s most powerful amplifier at its size. Ideal for subwoofers and lowfrequency devices requiring relatively high continuous power and ample headroom, the K20 is the unique result of smart design, attention to sound quality, and extremely high efficiency with reliability, portability, and adaptability in mind. Like all K Series models, the K20 is designed for, and absolutely stable with, 2 Ω loads, further reducing the number of amps required to power a specific system. Such enormous power density in a single 19” rack unit weighing as little as 12 kg/26.5 lb and running off a single mains phase is only possible due to unique Powersoft technologies, resulting in a remarkably high efficiency exceeding 85%
