Sub 50 delivers a dynamic sound that will fill your living room with powerful bass. Multiple inputs allow for several sources. A special high-level input can be used with power amplifiers to make even more convincing sonics attainable. The crossover frequency can be set in nine steps, adjusted by ear to your liking. The high quality MDF chassis is rigid and robust, guaranteeing beauty with longevity. Automatic amplifier mode engages the subwoofer with the presence of signal from any input. It will automatically revert to stand-by if idle for 10 minutes.
