CARE OF YOUR SPEAKER SYSTEM

The QPS-1 cabinet does not require any routine maintenance. When cleaning is needed, first make sure power is off, and then use a soft cloth, pre-dampened with a solution of mild detergent and water, to remove any fingerprints or to wipe off dust. DO NOT USE ANY OTHER CLEANING PRODUCTS OR POLISHES.

The metal grille can be cleaned with gentle vacuuming.
