The Polk Audio Atrium 4 outdoor speakers are designed to withstand all weather conditions and are resistant to high humidity, temperature changes, water exposure, and direct UV rays. They are an excellent solution for providing high-quality sound on small outdoor spaces where a comfortable audio environment is required. Due to their compact size, the Polk Audio Atrium 4 speakers have limitations in the low-frequency range, so in some cases, it is advisable to use them together with weatherproof subwoofers. However, thanks to their rich and dynamic sound, the Polk Audio Atrium 4 speakers excel at background music playback without additional support.
The rounded ABS housing of the speakers not only looks pleasant but also has excellent acoustic characteristics, preventing the formation of resonances. The exterior design of the Polk Audio Atrium 4 speakers in white or black colors allows them to adapt to almost any setting. The speakers have a two-way configuration, with both drivers featuring the patented Dynamic Balance construction by Polk Audio. According to this construction, the speakers are optimized in terms of sound and mechanical characteristics, harmonized with the speaker cabinet, and provided with the necessary damping. As a result, Polk Audio speakers with Dynamic Balance technology sound fuller and more dynamic than speakers of similar size from other brands.
The Polk Audio Atrium 4 speakers feature a 4.5-inch low-frequency driver and a 0.75-inch dome tweeter. The speaker's crossover filter is made of high-quality components in a scheme that minimizes phase and frequency distortions, and a pair of reliable screw terminals is provided for connecting the input cable.
The convenience of the speaker system in installation is ensured by the presence of a U-shaped swivel bracket. Using this bracket, the Polk Audio Atrium 4 speakers can be mounted in horizontal or vertical positions, and then oriented towards the desired area for sound distribution. The protective grille and bracket in the speakers are made of aluminum, making them resistant to moisture.
The Atrium series speaker systems meet the requirements of US military standards for environmental durability: "ASTM D5894-UV Salt Fog" (resistance to salt fog exposure), "Mil standard 810 Immersion" (military standard for water immersion resistance), and "Mil standard 883 Method 10098 for salt and corrosion" (military standard for salt and corrosion resistance).
