Defiance subwoofers deliver pure power, unleashed by clean, efficient amplification in a mix of six models, from entry-level to ultimate performance. With app control and Anthem Room Correction (ARC®), you’ll have powerful, perfectly balanced bass at your fingertips.

Ultimate, Uncompromising Bass.
Everything is maximized with the new Defiance X10 / X12 / X15 subwoofers. Output is massive, thanks to heavy-duty, internally-braced cabinets, and Active Ridge Technology (ART™) for maximum driver-excursion. Massive SPL levels are coupled with precision control, intense detail and vanishingly low distortion. Completely Crafted in Canada, Defiance X outperforms every sub in their class.
