Polk Audio presents speakers so tough that even a desert war zone can't kill them. The Atrium4 speakers feature stainless steel and brass hardware to eliminate rust worries, even when 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 4.5" mid/woofer with a mineral filled polymer cone and a 0.75" Anodized Aluminum dome tweeter with Neodymium motor structure. 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.

Exceptional Sound Quality The Polk Audio Atrium4 boasts a 4.5" Dynamic Balance, mineral filled polymer driver and a 0.75" Anodized Aluminum dome tweeter to deliver crisp highs and accurate lows for an immersive listening experience.
Military-Grade Waterproofing Built to military specifications for waterproofing, the Polk Audio Atrium4 is capable of withstanding water, salt and corrosion or any harsh environment for years of reliable performance anywhere in and around your home.
Dynamic Balance Technology The Polk Audio Atrium4 boasts exclusive Dynamic Balance Composite Material Technology to eliminate the performance-robbing resonance, so the sound is always clear and clean without any distortion.
