MARSHALL EMBERTON II General Troubleshooting

2-inch Full Range Transducer

The active driver is the primary source of mechanical vibration. Rattling often indicates a failure of the spider suspension or a deformed voice coil that is physically striking the magnet's pole piece during high-excursion playback, known as 'coil rub.' Replacing the driver restores the linear path of the cone and eliminates the percussive noise.

Passive Radiator Assembly

The Emberton II utilizes dual passive radiators which lack a motor structure but move in response to internal air pressure. If the silicone surround delaminates from the radiator's central mass, the mass will wobble and strike the speaker's internal frame, creating a distinct low-frequency rattle or buzzing sound.

Speaker Grill Mounting Kit

The metal mesh grills are held in place by internal clips and adhesive gaskets. If the speaker has been subjected to thermal cycles or physical impact, these gaskets can compress or fail, allowing the metal grill to vibrate against the plastic housing at specific resonant frequencies.
