SAFE LIMITS
OF OPERAT I O N
Your Polk Audio loudspeakers are made with
the highest quality materials for years of
t ro u b l e - f ree perf o rmance. However, damage
to loudspeakers can occur when an amplifier,
re g a rdless 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 contro l ) .
This results in very high levels of audible dis-
t o r tion, originating in the amplifier, which
adds a harsh, gritty sound to the music.
C o n t r a r y 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.
