Ultimate, Uncompromising Bass.
Everything is maximized with the new Defiance X12 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 X12 outperforms every sub in their class.
