Bose Smart Soundbar 600
Score: 82/100Rankings
The Polk Signa S4 is a slim 3.1.2-channel soundbar with Dolby Atmos and a powerful wireless subwoofer, delivering strong bass and clear dialogue. Its lack of a standard HDMI input and occasional Bluetooth hiccups limit connectivity flexibility. Ideal for budget-conscious TV owners seeking immersive sound in small to medium rooms.
The Bose Smart Soundbar 600 is a compact 3.0.2-channel bar that delivers immersive Dolby Atmos sound and built-in Alexa. Its main trade-off is the absence of a separate subwoofer, which limits bass depth. Ideal for small-to-medium rooms where space and voice control are priorities.

Professional reviewers commend the Signa S4 for its impressive bass output, clear dialogue thanks to VoiceAdjust, and effective Atmos height effects, noting it offers strong value in the entry-level Atmos segment.

Everyday users love the easy wireless sub setup, the room-shaking bass, and the clear speech reproduction, especially for movies and sports.

“huge soundstage”
“powerful bass that rumbles behind couch”
Professional reviewers commend the Soundbar 600 for packing Dolby Atmos, clear dialogue and a well-engineered five-speaker layout into a compact chassis, with TrueSpace upmixing praised as a differentiator. However, they caution that its modest width and lack of a dedicated subwoofer prevent it from delivering the same cinematic breadth and bass impact as Bose's larger, premium models such as the Soundbar 900 or Ultra.
Everyday users appreciate the Soundbar 600's small footprint, clear speech reproduction, and the convenience of built-in Alexa, noting that it creates an immersive soundstage despite its size. Common complaints focus on limited bass without a subwoofer, reduced soundstage width compared to bigger units, and the need to purchase a wall-mount bracket separately.
