Paradigm Defiance subwoofers deliver pure power, unleashed by clean, efficient amplification in a mix of six models, from entry-level to ultimate performance. The Defiance X12 Subwoofer features a 650-watt power amplifier with a dynamic peak of 1300 watts for quick bursts of bass punch. With app control and Anthem Room Correction (ARC®), you’ll have powerful, perfectly balanced bass at your fingertips. The Defiance X series of subwoofers is crafted in Canada.
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.
Patented Active Ridge Technology (ART™)
The farther the driver can freely move, the deeper the bass it can generate. Patented* ART driver design “overmolds” durable driver surrounds to allow the farthest possible throw without distortion or destruction. Greater excursion results in a measured 3dB gain in output, with a 50% reduction in audible distortion compared to drivers held back by standard surrounds.
* US patents: D654,4795 and 8,340,340B2.
Only available on Defiance X15, X12, and X10.
Subwoofer Control App
Simplify setup & tuning with the free Paradigm Subwoofer Control App*, available for iOS and Android devices. The app controls volume, low-pass filter, phase, deep bass and much more from the comfort of your listening chair. It features three preset listening modes and a built-in shortcut to the Anthem Room Correction (ARC®) app.
Anthem Room Correction (ARC®)
Using your mobile device or optional 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.
* Not available on Defiance V8
