The Cambridge Audio Minx X301 has a size of no more than 30 square centimeters, but it'll bring your movies and music to life without any effort. Thanks to its compact size and neutral design, you can give this subwoofer an unobtrusive place in your living room. The 200-mm driver's bass performance and passive radiator won't go unnoticed, though. Want to hear even more bass? Use the buttons on the back to adjust the volume and frequency settings.
