Polk Audio Atrium 8 SDI Speaker Review

-

The Polk Atrium 8 SDI outdoor speaker is the flagship of this particular line, which over time, has become one of the best patio speakers on the market. Obviously, this means that it is the biggest and the most expensive one in the range, but it made a good impression on me.

Sound Quality

The SDI in the name of the speaker refers to the single/dual input switch, which basically means that this speaker can be used on its own as a high-performance stereo speaker. However, with the flip of a switch, two of these speakers can be paired together to function as separate left and right speakers.

Even though the Atrium 8 can be used as a single speaker, for the best stereo spread, I would still recommend using these speakers in pairs.

This speaker features enough mid and low range that music doesn’t end up sounding hollow like on some cheaper outdoor speakers. It features two 1-inch tweeters and a 6 1/2-inch driver capable of crisp sound quality without distortion at high volume levels. Anyone who appreciates good audio will love the Atrium 8 sounds like a proper speaker and a less outdoor version of one.

Design

While the Polk Atrium 8 is relatively compact for what you get, it is still a large speaker. The cabinet features a durable, mineral-filled polypropylene design, and the bracing is molded-in. I also appreciate that the speaker is designed for easy installation thanks to its speed-lock mounting system. Once installed, the speaker is also very solid since its baffle design is more steeply-angled it can maximize frequency dispersion over a larger area.

While this speaker is not recommended for small spaces as it is quite powerful, its ability to run both channels makes it a good choice if you want stereo sound but not two separate speakers.

Durability

Concerning durability, Polk Audio went above and beyond what is required from an outdoor speaker. Rust is not a problem with the Polk Atrium 8, and extreme temperature or heavy rain shouldn’t pose any issues for this speaker. However, consider installing this under some eaves protection just for the sake of caution.

Features

Tucked away in this speaker, you’ll find patented technologies for both dynamic balance and Klippel optimization to ensure you get a more realistic sound.

Pros and Cons

As you can see, the Atrium 8 definitely has more pros than cons, and I had to look really hard to find anything to fault it with.

Polk Audio Atrium 8 Speaker Pros

  • Anodized Aluminum Tweeter Domes
  • Easy installation thanks to the speed-lock mounting system
  • Very good bass and midrange
  • Functions alone as a single stereo speaker or can be combined with another for a stereo pair
  • The rugged, weatherproof design makes this speaker extremely durable

Polk Atrium 8 Speaker Cons

  • The speaker is quite large

Verdict

This is the speaker to get if you have a large outdoor space or don’t want to compromise on sound quality. Anyone looking for a quality speaker that offers good value for money, plenty of features as well as a recognizable brand can’t go wrong with the Polk Audio Atrium 8. The only problem is that this speaker performs so well you will probably be tempted to buy another one or two.

  1. Purchased Polk Audio Atrium8 SDI speakers. Got a pair of them & I am more than just satisfied. Fills my patio & backyard with clear, clean, crisp sound. From Siri radio, cds, vinyl, even old time cassettes, all sound quite good. My taste run from Blues to Rock, Folk to Country Swing, Motown to big brassy band music. They all come through great. Very easy to install. Can’t wait til the quarantine is lifted and we can gather again to enjoy music. We all need music more than ever now.
