AMPLIFIER POWER REQUIREMENTS

Your new EX3 Loudspeaker will work well with a variety of electronic components. As little as 10 watts per channel will deliver adequate listening levels in most cars. If you have a noisy car or intend to play your system at loud listening levels, more power will be necessary to achieve the best performance.

Consult your Polk Audio dealer for specific amplifier recommendations.

SAFE LIMITS OF OPERATION

Your new EX3 Loudspeakers are made with the highest quality materials for years of durable, trouble- free performance. However, damage can occur to loudspeakers 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 “1 to 2 o’clock” position on the volume control. This results in very high levels of audible distortion, originating in the amplifier, which add a harsh, gritty sound to your music. Contrary to popular belief, a speaker is more likely to be damaged by trying to get too much volume from a low- powered amp than from a high-powered one.

TECHNICAL ASSISTANCE OR SERVICE

If, after following these hookup and installation directions, you experience difficulty, please double- check all wire connections.

Make certain your electronic equipment is operating correctly by hooking up another speaker to the speaker output. For example, if you are not getting sound from the left channel speaker, connect the right channel speaker to the left output. If you still get no sound from that side, the problem is in your amp or source electronics. Should you isolate the problem to the speaker, contact the authorized Polk Audio dealer where you bought your speakers. Authorized Polk Audio dealers are the best source for advice and assistance.

Polk Audio’s Customer Service Department is available from 9am–6pm, EST, Monday through Friday, at 800-377-7655, or via email polkcs@polkaudio.com. Please do not hesitate to contact us if you have questions about your speaker system.
