About this item

• Atrium series speakers exceed baseline industrial and military specifications for environmental endurance (ASTM D5894-UV Salt Fog, Mil Standard 810 Immersion, Mil Standard 883 Method 1009.8 for salt and corrosion)
• Anodized aluminum tweeter domes with rubber surrounds are absolutely immune to the elements, provide the smooth, broad high-end range you need for larger outdoor spaces
• Newly designed tweeter phase cap smoothest the frequency response from 12KHz up to 20kHz, the last audible octave
• Broad coverage baffle design adapted and applied from our current Atrium design but a more steeply-angled baffle design that maximizes critical mid and high-frequency dispersion over a large area
• Speed-lock mounting system for easy, safe one-handed installations even in difficult locations
