Sony HT-S40R
Score: 76/100
Polk Audio Signa S4
Score: 73/100Rankings

The Sony HT-S40R provides a solid 5.1 surround experience with wireless rear speakers and strong power, but its lack of HDMI inputs and object-based audio formats keep it from being a premium solution.

The Signa S4 is a low-profile 3.1.2-channel soundbar with a wireless subwoofer that brings Dolby Atmos immersion and clear dialogue to midsize rooms, while keeping setup simple and cost-effective.
