When you hear harsh sounding treble from any good loudspeaker indoors or outdoors turn the volume down immediately Those harsh sounds are masking some much more powerful ultra high frequency sound spikes which will quickly damage any fine loudspeaker Cleaning You can clean the OS loudspeakers with a dampened soft cloth or paper towel If the loudspeaker is mounted high up on a wall or ceiling use a broom to gently brush it off Hosing off the loudspeaker is not recommended as the tweeter is a precise mechanism which might be damaged by a high pressure stream of water Q m Z w r Q nu Q Z SPECIFICATIONS OS 7 5 Loudspeaker Recommended Amplifier Power 5W 150W Nominal Impedance 8 ohms Frequency Response 60Hz 23kHz 3dB Sensitivity 91dB for 2 83V pink noise Wiring Requirements Sixteen to eighteen gauge 2 conductor unshielded or shielded wire for runs up to eighty feet Fourteen gauge 2 conductor unshielded or shielded wire for runs up to two hundred feet Dimensions Loudspeaker with U Bracket 8 3 16 Wide x 13 5 16 High x 9 3 16 Deep Weight loudspeaker and Bracket 23 Ibs per pair 2 Year Limited Warranty OS 6 5 Loudspeaker Recommended Amplifier Power 5W 125W Nominal Impedance 8 ohms Frequency Response 70Hz 23kHz 3dB Sensitivity 90dB for 2 83V pink noise Wiring Requirements Sixteen to eighteen gauge 2 conductor
