Polk Audio Atrium 6 5-1/4" Outdoor Speakers (Pair, Black, Refurb)
The Polk Audio Atrium 6 is the workhorse of the outdoor speaker world, specifically engineered to deliver high-fidelity sound in wide-open spaces. Built to exceed military specifications for environmental endurance, these speakers are designed to withstand the harshest elements—from torrential rain and salt spray to extreme heat and freezing temperatures. Whether you are entertaining on a spacious patio or adding high-quality audio to a pool deck, the Atrium 6 provides a powerful, full-range performance with the deep bass and clear highs that Polk is famous for.
Installation is effortless thanks to the innovative Speed-Lock mounting system. This bracket allows for a one-handed, secure install and offers 180-degree rotation, so you can aim the sound exactly where you want it. Featuring a 5.25-inch mid-woofer with Dynamic Balance technology and a 1-inch aluminum dome tweeter, the Atrium 6 ensures a smooth, detailed response across the entire frequency spectrum. Housed in a durable, mineral-filled polypropylene cabinet with aluminum grilles and stainless steel hardware, these speakers are built to look and sound great for years to come.

Features:
- Heavy Bass Response: 5-1/4" long-throw aerated polypropylene cone driver with butyl rubber surround pumps out surprising bass response from a compact design.
- Aluminum Dome Tweeter: 1" anodized aluminum dome tweeter with rubber surround and neodymium magnet for better power handling and smoother response.
- Water-Resistant: Patented water-resistant PowerPort bass venting efficiently adds 3dB of big, realistic, musical bass output. No other outdoor speakers can touch the Atrium Series for deep bass you can feel from the ground up. And because it's Polk all-weather certified water-resistant, it can go practically anywhere with no worries about moisture impeding its performance.
- High-Frequency Dispersion: Broad coverage baffle design, adapted and applied from our current Atrium design but with subtle improvements in the new Atrium Series. A more steeply-angled baffle design that maximizes critical mid- and high-frequency dispersion over a large area, without sacrificing the detail.
- Durable, mineral-filled polypropylene cabinet design, with molded-in bracing, sounds like a real speaker (not "an outdoor speaker"), and survives years of seasonal changes, for truly great sound, no matter what the weather.
- Patented Dynamic Balance & Klippel Optimization Technologies: Ensures the perfect material performance, eliminating driver and tweeter "artifacts" for more realistic sound reproduction at high and low volume levels.
- Polk All-Weather Certified: Atrium Series speakers exceed baseline industrial and military specifications for environmental endurance (ASTM D5894-UV Salt Fog, Mil Standard 810 Immersion, Mil-Std 883 Method 1009.8 for salt and corrosion.) Certification means Atrium speakers can effortlessly withstand the worst Mother Nature can dish out, whether its extreme temps or heavy rains. With certification like this, your kitchen or bathroom installation is a cakewalk for Polk all-weather speakers.
- Rustproof Grilles: Aluminum grilles and bracket, with stainless steel and brass hardware: No rust. Ever.
