Internal Low-Frequency Transducer
The Sub Gen 3 relies on two drivers moving in perfect synchronization to cancel out cabinet vibration. If one driver's voice coil or suspension fails, the opposing force is lost, causing the cabinet to physically vibrate and the audio to sound muffled due to the loss of acoustic pressure and phase cancellation.

Acoustic Chamber Gasket Seal
This is a sealed (acoustic suspension) system. If the internal gaskets sealing the woofers or the cabinet halves fail, air escapes at high velocity (chuffing), which manifests as a 'noise' or rattling, while the loss of internal pressure prevents the drivers from reaching their intended low-frequency extension, resulting in a muffled sound.

Sonos S2 Firmware/DSP Calibration
Documented firmware regressions (e.g., v14.12) have historically caused the Sub to lose gain or shift its crossover frequency too high. This electronic profile change makes the sub sound muddy or muffled, and incorrect limiter settings can cause the drivers to bottom out or vibrate excessively against the housing.
