ART Driver

The ART driver coupled with the powerful amp and Anthem room correction gives us a subwoofer that can fill the role of an audiophile sub matched to fast mini-monitors or provide room-filling bass for home theater use.

ARC On Board

Anthem Room Correction, ART drivers, powerful amps, and stoutly built cabinets combine to give us far more tech than you normally see in subwoofers in this price category. The Anthem Room Correction (ARC) will work wonders in most rooms.

Made in Canada

The Defiance X Series is engineered, prototyped, and fully manufactured at Paradigm's 225,000 square foot facility in Canada. The attention to detail and craftsmanship really shines through on the Defiance X models.

Defiance subwoofers deliver pure power, unleashed by clean, efficient amplification in a mix of six models, from entry-level to ultimate performance. With app control and Anthem Room Correction (ARC), you'll have powerful, perfectly balanced bass at your fingertips.

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.

All Performance. No Gimmicks.
For intense bass performance with no gimmicks, Defiance V8 / V10 / V12 subwoofers are an amazing value. Smaller footprints pack tons of technology into a compact powerhouse of low-frequency impact. Pound for ground-shaking pound, Defiance V delivers the best bass at an unbeatable value.

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.

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, 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.
