POLK AUDIO Atrium 4 OUTDOOR LOUDSPEAKERS 10-80W PAIR

• 4 1/2-inch (11.43cm) long-throw mineral-filled polypropylene cone driver with butyl rubber surround pumps out surprising bass response from a compact design.
• 3/4-inch (19mm) anodized aluminum dome tweeter with neodymium magnet for better power handling and smoother response.
• Broad coverage baffle design, adapted and applied from our current Atrium design but with subtle improvements in the new Atrium Series. You want to fill a large open outdoor space with big, full-range sound. The new Atrium Series has a more steeply-angled baffle design that maximizes critical mid- and high-frequency dispersion over a large area, without sacrificing the detail.
• 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.
• Speed-Lock™ mounting system, for easy, safe one-handed installations even in difficult locations. The greatly simplified mounting procedure means fewer parts to "juggle." Simply mount the bracket and click the speaker into place. Aim it and tighten it down, and fini! Outdoor convenience, indoor sound quality!
• 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® and Klippel optimization technologies ensure the perfect material performance, eliminating driver and tweeter "artifacts" for more realistic sound reproduction at high and low volume levels.
• Aluminum grilles and bracket, with stainless steel and brass hardware: No rust. Ever.
• Gold-plated 5-way binding posts for the most secure, dependable hookups.
• Available in durable, weatherproof black or white paintable finishes.

2-way multi-functional speakers for shelf and wall mounting

This loudspeaker´s wall-fitting option means that it may be universally employed, it also doesn´t require much space because of its small size. Anything is possible – be it under the ceiling, for music or home cinema, at home or in studios!

The extremely compact two-way bass-reflex system accommodates a 160 mm low/mid-range loudspeaker and a high-resolution dome tweeter. The magnetically shielded case means that the Symbol Pro 160 may be excellently used as a near-field loudspeaker in direct proximity to a monitor.
