    Overview

    Much like their Roman namesake filled the home with light and fresh air, the Polk Atrium 8 SDI Outdoor Speakers have been designed to fill the outdoor spaces of your home with high-quality sound. The Atrium Series exceeds baseline and military standards when it comes to weather resistance, certified to withstand heavy rain, UV, and salt-fog, or harsh sunlight. Featuring 6.5 inch drivers and 1 inch tweeters, the Atrium 8 speakers can deliver high-fidelity sound for the faithful recreation of your favourite audio.

    Using the patented Dynamic Balance System, material performance within the speakers are enhanced, delivering greater sound realism at high and low volumes. With the PowerPort bass venting, your audio will be imbued with three decibels of impactful bass output. Using the single/dual input switch, you can use the Atrium 8 SDI as an individual loudspeaker or as L/R speaker in a high-performance stereo pair.
    Dynamic Balance

    Proprietary Polk Audio technology, Dynamic Balance serves to eliminate driver and system resonances that cause distortion. This leads to tight, controlled audio.

    Power Port Technology

    Reducing turbulence or 'port noise' at the mouth of the bass port, Power Port technology provides deeper, more impactful bass, with less distortion.

    Polypropylene Cabinet Design

    The durable, mineral-filled cabinet design features molded bracing to reduce internal resonance, while the resistant exterior thrives across seasonal and weather changes, delivering high-quality sound all year round.

    Five Year Warranty

    Confident in the high-quality make and functionality, this vacuum is backed by a five year manufacturer's warranty, for additional peace of mind.
