Polk Audio SR52505 Safe Limits Of Operation, For Technical Assistance Or Service, SR6500 SPECS

SAFE LIMITS

OF OPERATION

Your Polk Audio loudspeakers are made with the highest quality materials for years of trouble-free performance. However, damage to loudspeakers can occur when an amplifier, regardless of its wattage, is made to play at higher listening levels than its power can cleanly produce (usually beyond the “1 to 2 o’clock” position on the volume control). This results in very high levels of audible dis- tortion, originating in the amplifier, which adds a harsh, gritty sound to the music. Contrary to popular belief, a speaker is more likely to be damaged by trying to get too much volume from a low-powered amplifier than from a high-powered one.
