Know before you buy
Active Ridge Technology (ART™) allows the 15-inch driver to move further than traditional surrounds. This increased excursion results in deeper bass extension and significantly reduced distortion, even when playing at high volumes.
ARC® measures your room's unique acoustics and adjusts the subwoofer's output to compensate for problematic reflections and standing waves. This ensures your bass sounds tight and accurate rather than boomy or muddy, regardless of your room's shape.
Yes, the Defiance X15 is compatible with the Paradigm Subwoofer Control App. This allows you to manage volume, low-pass filter settings, phase, and room correction directly from your smartphone.
It is designed to excel at both. The combination of high-output power and precise control means it can deliver the visceral impact required for movie explosions while maintaining the nuance and speed necessary for high-fidelity music playback.
The X15 features versatile connectivity, including both balanced XLR and standard RCA inputs. This makes it compatible with a wide range of home theater receivers and dedicated stereo pre-amplifiers.
Because this is a high-performance 15-inch subwoofer with a robust, internally-braced cabinet, it has a significant physical footprint. You should measure your intended placement area carefully to ensure the cabinet fits comfortably while allowing enough room for proper airflow and cable management.
