Polk Audio presents speakers so tough that a desert war zone can't kill them. The Atrium 45 speakers feature stainless steel and brass hardware to eliminate rust worries even outside. These speakers meet or exceed various government standards for salt fog immersion salt and corrosion tests. The 5-way binding posts are gold plated to prevent corrosion. The speakers are a 5.25' mid/woofer with a mineral filled polymer cone and a 1.0' soft dome tweeter with a Neodymium magnet. The sculpted front baffle and round enclosure minimize diffraction and deliver a more open natural sound. The aluminum grill is 55% open for superior sound transmission without compromising the protection it gives the cones.Type: Indoor/Outdoor SpeakersDriver Units: Mid/Woofer: 1 - 5-1/4' Diameter (13.34cm) Dynamic Balance mineral filled Polymer with rubber surround Tweeter: 1 - 1' Diameter (2.54cm) Soft dome with Neodymium magnetPower Rating: 10 -100 w/channelFrequenc y Response: 60Hz - 20kHzNominal Impedance: 8 ohmsSensitivi
