## Overview

The Polk Audio Atrium 8 SDI is a premium all-weather outdoor speaker featuring a 6.5-inch Dynamic Balance woofer and dual 1-inch anodized aluminum dome tweeters. Designed for durability, it withstands extreme weather conditions including heavy rain, UV exposure, and salt-fog. Its innovative 180° speed-lock mounting bracket enables quick, secure installation with flexible orientation. The speaker supports single or dual input modes for versatile stereo configurations and connects easily via gold-plated 5-way binding posts.

## Description

Atrium 8 SDI features a single/dual input switch and dual tweeter array that lets you work the speaker as a single high-performance stereo loudspeaker, or L/R speaker in a high-performance stereo pair. It’s time to get that indoor sound you love - all from an outdoor loudspeaker you can put anywhere around your home. All-Weather Certified and Water-Resistant—built to withstand the worst elements—salt-fog, UV, extreme temps or heavy rains, you name it. Equipped with a Dynamic Balance driver and two tweeters the speaker provides a more realistic sound reproduction at high and low volume levels, and delivers clean midrange and deep, accurate bass. Durable speaker cabinet design with aluminum grilles and bracket, stainless steel and brass hardware survives years of seasonal changes without compromising on premium outdoor sound.

Review: These are what outdoor speakers should sound like - For some background, I’ve had a pair of Polk Audio Atrium 8 SDI speakers on my deck for about five years now, powered by a Sonos Amp, and they have been fantastic. I do not take them in during harsh New England winters, but I do put covers on them (plastic garbage bags taped with duct tape - really classy). I’m writing this review now because I just went through the process of buying another set of outdoor speakers to mount on our pool house, and that experience made me appreciate these Polks even more. Instead of buying another pair of these right away, I first tried the Sonos-branded outdoor speakers. I figured they would be a high-quality match with the Sonos Amp, given the much higher price. That was not the case. Their sealed enclosure was very light on bass, and the high end was lackluster at best. There was no sparkle, no brightness, and they sounded more like speakers that should cost four or five times less. They played very loud, and the harder they were pushed, the better they sounded... but I need to stay on good terms with my neighbors. I then picked up a pair of PSB outdoor speakers on sale because I’m a fan of the brand and have a home theater setup built around their Imagine line, which sounds fantastic. The PSBs were also paired with a Sonos Amp, and while they did sound quite good, they had a very small optimal listening area. That would be fine for a screened-in porch or a more focused seating area, but for a pool area or a deck where people are moving around, they were not the right fit for my preference. I should also mention that the mounting systems on both the Sonos and PSB speakers were not well thought out. They were more difficult than they needed to be, and I’m not sure what they were thinking. I was not able to even get the set screw to line up on the PSBs, not good. Now, onto the Polks. These speakers are big. They have two tweeters, and their design allows them to be used as a single stereo left-and-right channel speaker. I have not tested them in that format, but I would expect them to sound pretty good, similar to how a Sonos speaker uses multiple tweeters to play left and right audio from one cabinet. What sets these speakers apart comes down to a few things. First, they are extremely easy to mount. The bracket uses two screws with a wire hole in the middle, and the mount is thin enough that it can fit between shingles without having to span multiple rows and create angle issues. The speaker then pops into the bracket and can hold itself in place while you screw in the end caps. These feel like they were designed by people who have gone through the process of mounting outdoor speakers before. They are also very easy to angle. They only move up and down or left and right, depending on how you orient them on the wall, but adjustments are simple. You just loosen the end caps slightly and tilt the speaker into position. The first thing you notice when listening to them is the wide soundstage. The sweet spot extends across a much larger area, which is exactly what I want from outdoor speakers. This is their biggest strength. For a deck, patio, or pool area, they fill the space beautifully instead of sounding good in one narrow location. The second thing is the bass extension. They are ported in the back with Polk’s PowerPort design, and it does a very good job. A pretty significant amount of bass comes from that 6.5-inch woofer, especially for an outdoor speaker. They are also easy to drive. The Sonos Amp does not break a sweat pushing these to high volume. Do they sound quite as musical and accurate as the PSB speakers, with that sparkly high end and excellent midrange? No. But do they work much better in a large outdoor setting like a pool area or deck? Absolutely, hands down, every time. They sound good, and if they hold up like my 5 year old pair, I know I'll get many years of enjoyment out of them. Excellent value and big sound from a very well thought out package. These are an incredible pair of outdoor speakers. Well done, Polk.
Review: Built like a time capsule and sound fantastic - These sound fantastic with deep base and crisp clear mids and highs. My last set were 15-years old and still going strong. My speaker wire had corroded upwards about 8-inches but the speakers themselves showed no sign of corrosion. I wanted a larger pair which is what drove the switch more than anything else. This time I used Sewell deadbolt banana plugs and dielectric grease to prevent corrosion this time.

## Questions & Answers

**Q: Are these original speakers?**
A: No, there were speakers long before these existed.

**Q: Does it need to be plugged in at all times?**
A: These speakers require speaker wire to be connected to them when being listened to. There is no power cable to be plugged in.

**Q: Is this a single speaker or a pair of speakers?**
A: Since this question was asked regarding the Atrium 8 version but Amazon shows it under both the 6 and 8 version, the Atrium 8 version is sold as a single speaker. The Atrium 6 version (and smaller) are sold as pairs.

**Q: What is the rms wattage per speaker? I cannot get a straight answer!**
A: Polk claims they will handle up to 125 watts per channel, but with a sensitivity of 91dB 《8 ohm) these speakers get very loud quickly. I have an older Technics H class receiver (100 watts p/ch) & have never pushed over half volume on my pair. Note: I do enjoy cranking it up. With a freq. response of 45 - 27,000Hz, I found a sub wasn't needed. Placement, area & environment ( walls, height, corner availability) make a big difference when installing them correctly, but wattage shouldn't be a concern. These speakers are a great buy for the price.
