I have been pairing a Sony SSCS8 center speaker with Polk S55 towers for a year. I was mostly happy with the Sony speaker. Since I liked my S55 towers, I chose the Polk S30 center channel. I've had him for about 2 months now. I mainly watch Netflix movies. And I was initially very disappointed with the Polk S30. Male voices (especially male bass voices) are unclear. The autocorrect software on my receiver has improved things but is still not satisfactory. Sony's center speaker handled the wider vocal range better. Then one day while watching Blu-ray movies I found that the Polk S30 sounded much better including bass male voices. So if you're using a high-quality audio source like a Blu-ray disc, you'll love the S30. . If you stream, save money and choose the Sony SSCS8 Center. The main reason I bought the S30 is because I've had S55s before. The shelves are powered by a Yamaha RX-V675 on my system. I would give 3.5 stars but I can't. Polk S55 gets 4 stars from me. But you can do better with direct internet companies for the same price. Hope that helps. Update March 24, 2020: I downgraded my rating to 3 stars after a few months of use due to the previously mentioned issues.
