All Magnat subwoofers are designed to reproduce deep bass in a powerful way and up to the performance limit. To enable them to do this safely, we have equipped all the subwoofer power amps with a Real Time Limiter (RTL). The component protects the subwoofer against damage and, at the same time, provides for more gentle limitation of the signal in the borderline area. This prevents hard clipping of the signal, with the bass signals sounding harmonious and natural over the entire bass frequency range.
