Bought a couple outdoor speakers and they just didn’t have the mods and lows that I was looking for. These speakers are absolutely perfect. They have crisp voice clarity, while hitting the mods perfectly. Give these a shot if you are a perfectionist!

Very pleased with the full range sound quality. I upgraded from Yamaha NS150 speakers for a 5hz greater low frequency extension. The speakers are a bit larger than the Yamaha and seem to provide more realism, warmth, and fuller sound. I installed in the corners of my deck gazebo and use a powered sub for additional low frequency support.

Outstanding when run in a stereo pair. I have probably run my pair for about 100 hours, and they rich and responsive over the full audio range which is no mean feat for outdoor speakers. A great piece of engineering from Polk.

I purchased these in 2018, and they've been outside in the Arizona Sun for at least 6 years now and still working great. The sound quality is good; better than I would expect for an outdoor speaker and more importantly they have held up in some of the most brutal conditions. They have definitely earned five stars at this point.
