Optional Wireless Module
Place your subwoofer anywhere in your room, with no inconvenient cabling, and without sacrificing speed or performance. The Defiance WT Wireless Module* (sold separately)features fast and clear 2.4 GHz dynamic frequency selection with instant error correction and a 50ft range. * Not available on Defiance V8

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
