Getting Started
Please inspect your loudspeaker(s) carefully. Notify your Polk Audio dealer if you notice any
damage or missing items. Keep the carton and packing material; this will do the best job of
protecting your speaker(s) if they must be transported.
Safe Limits of Operation
Your Polk Audio Loudspeakers are constructed of 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 clearly
produce. This is usually beyond the "noon or 1 o'clock" position on the volume control.
Operation at this level can result in very high levels of audible distortion originating in
the amplifier, which can add a harsh, gritty sound to your listening material. If you hear
distortion—turn it down! Contrary to popular belief, a speaker is more likely to be damaged by trying to get too much volume from a low-powered amplifier or receiver than
from a high-powered one.
Technical Assistance or Service
If, after following the hookup directions, you experience difficulty, please double-check all
wire connections. Should you isolate the problem to the speaker, contact the authorized
Polk Audio dealer where you made your purchase, or contact Polk Audio Customer Service
800-377-7655 (M-F, 9-6 EST, US only) or via email polkcs@polkaudio.com. Outside the US,
call 410-358-3600.
