Polk vs JBL: value Atmos bar with a wireless sub against a full 7.1.4 system with detachable surrounds.
Updated 2026
Verdict
Buy the JBL Bar 1000 if you want real rear surround speakers (detachable, battery-powered) and a 10-inch wireless subwoofer in a 7.1.4 Dolby Atmos and DTS:X system. Buy the Polk Signa S4 for a slimmer, simpler Atmos bar with a 5.9-inch wireless sub and VoiceAdjust at a lower price.

The table compares format, surrounds, subwoofer, output and streaming; the split is slim value against a bigger, true-surround system.
You want an Atmos soundbar that fits under a TV in a small or medium room, sets up with one cable in minutes and offers adjustable voice levels.
You have a larger room, want real rear speakers and a bigger sub, and care about streaming support such as AirPlay and Chromecast.
You are building a full home theater with a receiver. A soundbar of either type cannot match separates for placement and power.
If you want actual rear speakers and a larger sub, yes. If your room is small and you want a simple, slim bar, the Polk is enough.
Yes. The JBL also supports DTS:X.
They are detachable and battery-powered, so they need charging but no speaker cable.
Use an HDMI eARC (ARC) port on the TV for best format support.
