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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***T on April 19, 2026* ### ⭐⭐⭐⭐⭐ Review *by F***Y on April 4, 2025* ### ⭐⭐⭐⭐⭐ Review *by R***B on September 1, 2022* ## Frequently Bought Together - Polk Audio Atrium 8 SDI Flagship Outdoor Speaker (Black) - Use as Single Unit or Stereo Pair, Powerful Bass & Broad Sound Coverage, Withstands Extreme Weather & Temperature - Sonos Amp - The Versatile Amplifier for Powering all your Entertainment - Black - Polk Audio RC80i 2-Way Premium in-Ceiling 8" Round Speakers, Set of 2 Perfect for Damp and Humid Indoor/Outdoor Placement - Bath, Kitchen, Covered Porches (White, Paintable-Grille) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/1159312-atrium-8-outdoor-speaker-with-powerful-bass-each-black-all](https://www.desertcart.us/products/1159312-atrium-8-outdoor-speaker-with-powerful-bass-each-black-all) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-16*
