Paradigm X-300 Ultra-Class-D Subwoofer Amplifier


**Trade-in Subwoofer Amplifier as is, No Packaging Provided. Pick Up Only**

The Digital Signal Processor design, or DSP design, on the X-Series contains sophisticated algorithms that shape frequency response. This ensures accurate, consistent and musical bass performance without audible distortion, even when the subs play at the loudest levels.

Easy-to-adjust front-panel controls are also a feature on the X-series. Once you’ve adjusted and set your controls to the desired settings a glass cover attaches magnetically which not only keeps the X-300 looking sleek but also stops prying hands meddling.
