Description
Build & Sound Quality
The Polk Audio Atrium 4 is built to last. The housing is made from a very durable mineral-filled polypropylene, while the grille is made from coated aluminum. This keeps things very lightweight and ensures no rusting will occur.
The speaker bracket and fixings are included with this speaker, and the Speed Lock mounting system with keyhole slots makes installation easy and hassle-free. The speaker can be angled 45 degrees in either direction, to create the perfect positioning. Because of its compact size, the Atrium 4 is also very discrete and can be installed without any intrusion.
The Atrium 4 boasts Power Port Technology, allowing the speaker to smoothly transition air flow from the speaker into the listening area for deep, extended bass impact while minimizing turbulence and distortion.
Weather Resistance
The Atrium 4 is made from 'military-grade' components designed to withstand any weather condition. Lots of speakers state they are outdoor-rated, but they ideally still need to be covered under some form of shelter to reduce the risk of damage.
The Atrium 4 speakers can be installed in the open, exposed to the elements without this worry. This is because they have been built to withstand extreme temperature ranges - hot and cold, fog (includes salt-fog), heavy rain and UV.
