Everything is maximized with the new Defiance 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 outperforms every sub in their class.

Using your mobile device or calibrated microphone (included with Defiance X models, sold separately on Defiance V models*), ARC measures your space, compares it to lab standard using proprietary advanced DSP algorithms, and instantly removes performance-robbing anomalies. The result is easy to hear: realistically blended, accurately rendered deep bass. Professional room correction at the touch of a button.

Tuned ports turn the floor into a tool for enhancing bass response, allowing more flexible placement options with no risk of turbulence or distortion.

Reinforced cabinet construction and vibration killing driver design delivers deep, detailed bass.

All X Series subwoofers are designed, engineered and manufactured in our state-of-the-art 225,000 ft2 Canadian facility.

Made in-house and overmolded directly onto each woofer cone. This design achieves greater excursion, for a 3dB gain in output and 50% reduction in distortion. Crafted from injection-molded thermoplastic elastomer, ART surrounds are more durable and more reliable than conventional surrounds, ensuring a lifetime of superior sound.
