The Cambridge Audio Minx X301 is only 30 square centimeters in size, but brings your movies and music to life effortlessly. This active subwoofer is discreetly concealed in your room due to its compact size and neutral design. What does attract attention is the bass performance of the 200 mm driver and the passive radiator. Do you want to hear the bass better? Then adjust the volume and frequency settings with the buttons on the back.
