Ultimate, Uncompromising Bass.

Everything is maximized with the new DefianceX10 / X12 / X15subwoofers. 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. CompletelyCrafted 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.

Anthem Room Correction (ARC)

Using your mobile device or optional calibrated microphone (included with Defiance X models, sold separately on Defiance V models*), ARCmeasures 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.
