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.

Using your mobile device or optional calibrated microphone (included), 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.

"There’s no lethargy here. No boom. No bloat. And a surprising lack of distortion. Those factors, combined with the X15’s colossal output above 40Hz, make it a beast to contend with."
