    Like all Polk products, works flawlessly and does exactly what it’s designed to do. I love my outdoor deck system with these speakers.

    My home theater runs on all Polk speakers and I am very satisfied with their quality. My issue with these outdoor speakers is they lack bass. I didn't do a lot of research because I got a great deal on an open box. They have quality sound but if I was really serious about a "rockin" outdoor system, I would look at their mid price or high end offerings.
