LG S70TR — A Budget 5.1 Soundbar System With Rear Speakers
The LG S70TR packages a soundbar, wireless subwoofer, and two wireless rear speakers for approximately $500 — half the price of the S90TR while still providing physical rear channel speakers. It lacks the S90TR''s Atmos up-firing drivers and has fewer total channels (5.1 vs 7.1.3), but the inclusion of actual rear speakers at this price separates it from soundbar-only systems that simulate surround effects.
Sound Configuration
The soundbar handles front left, center, and right channels. No up-firing Atmos drivers — the S70TR processes Dolby Atmos content but virtualizes the height channels through the front-firing speakers rather than bouncing sound off the ceiling. Virtual Atmos is audible as a slight expansion of the sound field but doesn''t create convincing overhead effects. If Atmos height channels are important, the S90TR or a dedicated Atmos soundbar is necessary.
The wireless rear speakers provide genuine surround from behind the listening position. This is the S70TR''s main selling point — even budget rear speakers dramatically improve movie immersion compared to any soundbar alone. The rears handle ambient surround effects, environmental sounds, and directional audio panning from front to back.
The wireless subwoofer produces bass down to approximately 40Hz. Adequate for most movie content but lacks the sub-30Hz extension that dedicated home theater subwoofers achieve. Explosions have impact; the deepest rumble in bass-heavy music doesn''t fully register.
LG TV Integration
Same seamless LG TV integration as the S90TR: TV remote volume control, WOW Orchestra mode, and automatic sound mode switching. eARC connection supports lossless audio formats including Dolby TrueHD and DTS-HD Master Audio.
At $500
- Physical rear speakers create genuine surround at a budget price point.
- Wireless subwoofer and rears — no speaker cable routing needed.
- Seamless LG TV integration with WOW Orchestra mode.
- eARC HDMI supports lossless audio passthrough.
- No true Atmos height channels — virtual processing only.
- Subwoofer bass extension is limited compared to dedicated subs.
- Rear speakers still need power outlet access — wireless audio, wired power.
- Dialogue clarity in the center channel can be thin compared to soundbars with dedicated center drivers.
The S70TR is the cheapest path to a complete soundbar system with physical rear speakers from a major brand. The surround improvement over a soundbar-only setup is substantial. For LG TV owners who want better-than-soundbar surround without a receiver, the S70TR hits the practical sweet spot of performance and simplicity at $500.
