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.
