Paradigm Defiance X15 Ultimate Subwoofer

The Paradigm Defiance X15 Ultimate Subwoofer’s 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.

  • PARADIGM DEFIANCE X15 PORTED SUBWOOFER REVIEW – Paradigm has long understood the importance of subwoofers to modern sound systems and the impact that a good sub can have on the overall sound. The Defiance X15 continues Paradigm’s trend as one of the few major loudspeaker manufacturers who take subwoofers seriously.

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

Partnered with the NRC
Paradigm is partnered with Canada’s world-renowned NRC in ongoing research to reveal the true nature of sound and human hearing. Findings influence design and performance specs, resulting in a uniquely realistic listening experience, backed by sound science.
