The Paradigm Subwoofer Control App uses a Bluetooth connection to simplify setup and configuration of compatible MartinLogan subwoofers. App based controls include volume level, low-pass filter (frequency and order), phase, deep bass level, three preset listening modes, and control of Anthem Room Correction. A unique tone sweep feature assists users in locating areas in listening rooms where troublesome rattles or resonances may occur. A single press of a button allows listeners to initiate a tone sweep from 20–120Hz. If a rattle or resonance occurs in the room any frequency can be held, allowing the listener to investigate and identify the source of the unwanted noise. Supported Devices: • Paradigm Defiance V10 • Paradigm Defiance V12 • Paradigm Defiance X10 • Paradigm Defiance X12 • Paradigm Defiance X15
