Paired with a sub provide well balanced sound with a bit of eq. Without the sub the bass are a bit weak… ### ⭐⭐⭐⭐⭐ Pair them with a good Amp and you’re in for a treat! *by on Reviewed in the United Kingdom 19 April 2026* 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! ### ⭐ Damaged on delivery *by on Reviewed in the United Arab Emirates 15 October 2022* Whilst the box was not damaged the speaker grill on 1 speaker had a big dent.Good sound but disappointed that it was damaged. ## Frequently Bought Together - Polk Audio Atrium 4 Outdoor Speakers with Powerful Bass (Pair, Black), All-Weather Durability, Broad Sound Coverage, Speed-Lock Mounting System - Fosi Audio BT20A Bluetooth Stereo Amplifier, 2 Channel Home Audio Component Amplifiers for Passive Speakers, Mini Class D Amp Receiver 200W for Indoor/Outdoor/Garage/Ceiling/Bookshelf Speaker - GearIT Outdoor Speaker Wire CCA 2x2.5mm≤ (60.96 Meters - Black) Copper Clad Aluminum - Hi-Fi Audio Cable for Direct Burial in Ground/in Wall / CL3 CL2 Rated / 2-Conductors - 14 Gauge AWG, 200 Feet --- ## 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.gr/products/113663985-polk-audio-atrium-4-80-watt-outdoor-speaker-black](https://www.desertcart.gr/products/113663985-polk-audio-atrium-4-80-watt-outdoor-speaker-black) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-19*
