Featuring a sleek, modern design with a low-profile white finish, the Arc Ultra fits elegantly in most living rooms, although it is quite large at over 46 inches wide and weighs 12.7 pounds. It is intended for indoor use only, as it is not water-resistant. While it includes built-in microphones for voice control, adding a subwoofer or rear speakers (sold separately) can enhance the surround sound experience. This soundbar is ideal for those seeking a high-end, easy-to-use device with excellent spatial audio performance, especially if size and quality are priorities over compactness or budget.

This setup ensures clear and immersive sound, making it a great choice for home entertainment. The sound bar also features Polk's Voice Adjust Technology and Dolby Digital 5.1 decoding, which enhances dialogue clarity and overall sound quality.

Connectivity is versatile with options for HDMI ARC, optical input, and a 3.5mm audio jack, allowing easy integration with 4K and 8K HD TVs. Additionally, the built-in Chromecast and Bluetooth support enable seamless wireless streaming from various devices, and Google Assistant integration adds convenient voice control functionality. The ultra-slim design at just 2 inches tall allows it to fit comfortably in front of most TVs without obstructing the view or the remote sensor, and it can also be wall-mounted if preferred.

Despite its numerous strengths, some users might find the lack of more advanced sound customization options a limitation. However, the setup process is user-friendly, with included HDMI and optical cables for quick and hassle-free connection. For those looking to enhance their home theater experience with quality sound, easy streaming, and smart assistant features, the Polk Audio Signa S3 is a valuable option.

It excels in audio quality, delivering clear, immersive surround sound that adapts to your room thanks to its Sound Field Optimization feature. This makes it a great choice if you want rich, room-filling sound for movies, games, and music.

While the product brief does not explicitly confirm built-in Google Assistant support, the soundbar offers multiple connectivity options including Wi-Fi, Bluetooth 5.2, Spotify Connect, and Apple AirPlay 2, making streaming music straightforward and flexible. The soundbar’s size is quite large (over 51 inches wide), so it works best in medium to large living rooms and may require careful placement, either wall-mounted or on a table. Its sleek, modern design with a metal build looks premium but could be bulky for smaller spaces. Setup and daily use are user-friendly, with included accessories like a remote and HDMI cable to get started easily.

Additional features like 360 Spatial Sound Mapping and expandability with optional subwoofers and rear speakers allow for a more immersive and customizable home theater setup.
