Introduction
The radiators aren't powered on their own, but are vibrated by small air pressure changes inside the speaker as the drivers vibrate. Radiators increase the volume of lower frequencies, slightly amplifying the bass. It may be hard to notice a malfunctioning radiator, but if your radiator has apparent physical damage (punctured, etc.), you may want to replace it.
This guide is for the left (when looking at the front) radiator, circled in the page's thumbnail.
