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.

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), 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.
