Sub Box 50 – Small and powerful

The Sub Box 50 delivers a dynamic sound that will fill your living room with powerfull basses. The multiple inputs let you connect many different sources. A special high level input can be used for power amplifiers, that makes an even more convincing sound possible. The crossover frequency can be set in nine steps, adjusting to your preference.

The high quality MDF chassis is rigid and robust, guaranteeing a long lasting life. The automatic amplifier mode turns the subwoofer on as soon as there is a signal at any input present. It will automatically put the subwoofer into stand-by mode if there hasn‘t been an active signal for 10 minutes. The high feature set and outstanding sound quality make Sub Box 50 a real high end solution.
