Review: recommended - Very good sound quality for the price. Paired with a sub provide well balanced sound with a bit of eq. Without the sub the bass are a bit weak… Review: Pair them with a good Amp and you’re in for a treat! - These really are quite a remarkable pair of speakers when paired with a good quality amplifier! I originally powered them with a Fosi HT4S and they sounded ok but pretty rough in the midrange. Then I tried a Wiim Amp and they sounded much better, nice and refined and balanced but I just had a feeling they could go further. Then I bit the bullet and got a second hand Arcam SA10 and that really brought them to life! Amazing clarity and such great warmth from the Arcam. They are lacking in bass but as they’re the smallest in the range that’s to be expected. I’ve already decided to upgrade to the Atrium 6 and move the 4s to a quieter part of the garden. All in all a fantastic pair of speakers! Great build quality, fantastic sound and easy to fit. Power them with a good quality amplifier and you’re in for a real treat! ## Technical Specifications | Specification | Value | |---------------|-------| | Audio Output Mode | Surround | | Brand | Polk Audio | | Connectivity Technology | wired | | Frequency Response | 25 | | Mounting Type | Tabletop Mount | | Speaker Maximum Output Power | 80 Watts | ## Product Details - **Audio Output Mode:** Surround - **Brand:** Polk Audio - **Connectivity Technology:** wired - **Frequency Response:** 25 - **Speaker Maximum Output Power:** 80 Watts ## Images ![Atrium 4 80 Watt Outdoor Speaker (Black) - Image 1](https://m.media-amazon.com/images/I/71KgV5mMghL.jpg) ![Atrium 4 80 Watt Outdoor Speaker (Black) - Image 2](https://m.media-amazon.com/images/I/41MoU6dsbtL.jpg) ![Atrium 4 80 Watt Outdoor Speaker (Black) - Image 3](https://m.media-amazon.com/images/I/61ZYDtjnLhL.jpg) ![Atrium 4 80 Watt Outdoor Speaker (Black) - Image 4](https://m.media-amazon.com/images/I/51g8hPxq0NL.jpg) ![Atrium 4 80 Watt Outdoor Speaker (Black) - Image 5](https://m.media-amazon.com/images/I/71TrQ6oQfSL.jpg) ## Questions & Answers **Q: Can it be connected to via bluetooth/ wifi?** A: No you need Amplifier for these passive speakers **Q: Which amplifier support atrium 4 speaker along with atrium sub100** A: Pls consider yamaha RS 202 or Yamaha R-N303 best Stereo Amplifiers **Q: Who provides warranty for Polk Audio's products in India?** A: PRO FX provides warranty in India. **Q: Is this speaker waterproof** A: Polk Atrium speakers can be installed in open spaces.
