A great system at a great price

I really like it. I needed a few extra steps to set it up, but that was due to the age of my TV. I have a small tweak to make, but the sound is excellent, and the design is simple and elegant.

Amazing sound quality

We are really enjoying this unit - especially the atmos feature. Our LG wireless base unit stopped working and after a bit of research we decided on the Polk unit. The sound is amazing. We have it hooked to our 65" LG smart TV in our master bedroom as we love to watch a movie before bed. I have found myself looking around the room to see where various sounds are coming from... and then realizing that they are coming entirely from the Polk S4 system. We are very pleased with this purchase.
