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,
r
egardless 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-
tor
tion, 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.
