## Description

These Polk audio outdoor speakers deliver exceptional sound anywhere. The compact Atrium 5 Outdoor Loudspeaker meets or exceeds military specs for environmental endurance. Its small size fits tight spots by the pool, on the deck, around the kitchen or filling the backyard with great sound. Easy-mount hardware lets you enjoy high-performance audio in every season, and durable, weatherproof black or white paintable finishes. For homeowners interested in outdoor entertaining, these outdoor pool speakers couple a 5" Dynamic Balance long-throw mineral-filled polypropylene cone with butyl rubber surround pumps out surprising bass, and a 3/4" anodized aluminum dome tweeter with neodymium magnet for smooth response. A steeply angled baffle maximizes mid- and high-frequency dispersion over large areas without sacrificing detail. As wired speakers for stereo or multi-zone setups, Atrium 5 uses the proprietary Speed-Lock system for one-handed installation; simply click, aim, and tighten. Polk All-Weather Certification means Atrium Speakers can effortlessly withstand the worst mother nature can dish out, whether it's extreme temps or heavy rains. Compact yet powerful, Atrium 5 offers award-winning Polk Audio sound, four-season durability and effortless placement—ideal for any music lover’s patio, garage or backyard.

Review: Great outdoor sound with an easy mounting system - Why I ordered this item: I've got a covered patio and my old bookshelf speakers were rusting out from humidity. Wanted something built for outside that could get loud enough over the pool pump. Likes: * Sound is crazy good for outdoor speakers. Bass punches through even with the pool pump running. * The mounting bracket is snazzy. You click the speaker onto the wall plate and it locks in, no separate screws once the bracket's up. * I can angle these up or down after they're mounted. Useful since my wall isn't at ear height. * Build feels tough, the finish shows no rust or fading spots. * They're not huge. Tucked into the corner of my patio they kind of disappear. No likes: * The included wire leads are short. I had to splice in more speaker wire to reach my receiver. * Volume knob (well, the whole thing) has no on-board control. You're stuck adjusting from whatever amp you've got them wired to. Would I pay full price for this product: Yes Final thoughts: These are made for a covered outdoor space where you want real speaker sound and not a bluetooth puck. The bracket system is the best part, mounting took me maybe twenty minutes total. If you don't already have an amp or receiver to power them, factor that into the cost.

## Questions & Answers

**Q: Is it two packs of pairs being a total of 4 speakers?**
A: No the 4 is for the size and model, there is only 2 speakers in the box!
These are Great Speakers!!!

**Q: Is it easy to be operated? I hope it will be not too hard to do that...**
A: …Were very easy to set up, and I just connected to the amplifier and then to the record player.…You can buy this amplifier if you are a lack of it.https://www.amazon.com/Bluetooth-Amplifier-Receiver-Integrated-Audio/dp/B07L3F5QQ7

**Q: How would these hold up to a Minnesotan winter ? I would place under a 2.5ft eve, but it would be exposed to the harsh winters.**
A: I'm on the north coast of Ohio. Mine are in the overhead of a covered porch Just as a precaution, I always bring mine back in for the winter.

**Q: What size amp do I need to run these with a car stereo? 2 channel, 100W?**
A: I actually just did a portable system using a car amplifier vs a stereo and used rca to head phone jack to plug in a phone or iPad.
I bought the  cheapest 2 channel on Amazon, not even a brand name, it was a power acoustic rated at 1400w. Which is way over kill, but only cost 58 dollars. And it was way lounder then what I needed it to do.  Don't forget about ohms on the speaker and the amp, being briged also, there is a lot of power available
