Maintaining Your Speakers
Cleaning the speakers
Wipe the grilles using a soft cloth dampened with a mild detergent, such as dish soap. When cleaning near the speakers with a hose, be careful to avoid forcing water behind the grille, onto the driver, or into the acoustic ports.
No other regular maintenance is required.
