. Despite a thorough testing of the synthetics used by us, we cannot rule out the possibility of staining . Do not place the KH 805 on delicate surfaces . The bottom of the subwoofer features rubber feet which reduce the risk of scratching the sur- face and the subwoofer cabinet, and acoustically isolate the subwoofer from the surface . -
