I'm driving mine with a $20 (Parts Express, $30 on Amazon) Lepai amp and older dot w/audio out. It's a great setup that is part of a whole house system. With Alexa and Spotify, I can play music inside and out.
Generally speaking they are a solid set of speakers. They give a pretty balanced sound all around but lack a little fullness in the lower mid-range. This is particularly noticeable when playing orchestral type music like film scores or piano heavy music. Going from the lower mids to bass is where they really start to have trouble. For the size of the speaker I certainly wasn't expecting to really "feel" bass but these do drop off noticeably in the lower frequency ranges. If there's something to knock with the Atrium 4's, that's it. With other types of music (country, rock, etc...) those issues aren't as noticeable. With that said they offer a nice high end treble sound that is pleasing to the ear. Overall the tone is brighter than I generally prefer (all of my JBL's have a warmer tone) but it certainly isn't a deal breaker for me. They don't by any stretch of the imagination sound unpleasant. For our purposes, general entertaining...using them for music outside while we do yard work..., they fit the bill very nicely. For $100 I am overall satisfied with this purchase. If you can afford to, or if a flatter overall response is important, then I'd probably look at something a little more expensive. If you are comfortable giving up some sound quality or if budget is an issue then certainly gives these a serious look.
Installing these babies was an absolute breeze. The mounting hardware supplied by Polk is virtually idiot proof. It simply could not be any easier to mount these speakers. The installation deserves 5 stars. The fact that they are virtually weatherproof is also a plus, you can mount them just about anywhere without fear of damage from the elements. One other thing I really liked was the ability to swivel and aim the speakers to exactly where I wanted them (this could not be done with our JBL's these replaced).
Power handling has not been an issue for me. I've got them hooked up to a 120 watt receiver and they been flawless to this point even at high volumes. We have a relatively large back yard so it takes some juice to disperse the sound and the Atriums are more than capable of taking it.
I'll summarize this way; if you're looking for an inexpensive way to get good quality sound outdoors with something that is ridiculously easy to install then the Atrium 4 deserves strong consideration. If you can afford to get in to an upgraded version then I would probably look in that direction solely for a better bass-lower midrange performance.
