RBH Sound S-10 - Manual (Page 4)

Break In Period
Allow several hours of listening time to adequately break-in the subwoofer. As
the subwoofer breaks-in, the driver suspensions will loosen. The result of break-in
will be an increase in low frequency response, improved definition, and increased
clarity and detail.

Care and Cleaning
2
To maintain your subwoofer’s appearance, we recommend wiping it down with
a clean damp soft cloth. To clean dust from the grille cloth, use a vacuum with a
brush attachment.
