    • They kick bass!
Color: Black Style: Atrium 4
I am a Polk fan having had those as my primary home theater speakers, but in my theater I have a large subwoofer and don't use the Polk speakers for bass. These outside speakers are about the same size and so I was doubtful of good low frequency (bass), but I was wrong, they have strong bass for such a small package. And also impressive they do that outside on my deck with no walls, which makes it easier for sound in general to get lost. If I crank it up I can hear music pretty well 100's of feet away. You may want to avoid that if you have close neighbors! As far as outdoor durability, seems good so far, I've had mine up for about 3 months and they look about the same other than a little dirty. Spend a little extra over the cheaper outdoor models and get these! ... show more

    • Excellent outdoor speakers
Color: White Style: Atrium 4
I purchased these outdoor speakers to replace an older set (connected to an indoor system) on my patio. They are mounted under 3 foot eaves that can cause muffled and overly-bass sound. These speakers are easy to install and can be positioned vertically or horizontally. I lowered the height equal to the bottom of my eaves and mounted them vertically, spaced at approx. 30 ft. The sound quality is impressive with clearer sound than my old ones. I don't notice distortion at higher volumes, but then I use these mostly for background music anyway. ... show more

Just recently installed these speakers with a Pyle PDA7BU Receiver. The sound quality is amazing. Very happy with my purchase. Would recommend And would buy again. I installed these in our bus garage and they project sound nicely and fill up the room with sound so you don’t have to have it as loud.

    • Sound is decent for their size.
Color: Black Style: Atrium 4
I got these for the cabin of my boat. They sound okay, but I've heard better sounding speakers for the same size. That said, I would say that I'm satisfied if not blown away.

    • Great sound!
Color: White Style: Atrium 4
The speakers mount and connect (wired) easily. They sound very good - - especially, for the price. I selected the Atrium 4 because I wanted a compact/smaller speaker that could be tucked in the soffit of our home.
