Sony HT-S40R review

A 5.1 soundbar system with real rear speakers, color-coded setup and dialogue enhancement.

In brief

A soundbar with real rear speakers and color-coded plugs — the only product here that is both complete and simple. Its catalog weight is one pound, for a four-piece 5.1 system. Key figures: 5.1 channel home theater soundbar system with a stated 600 W total power output, real rear surround speakers, color-coded connections, wireless music streaming, HDMI, optical and analog connections to the television, selectable sound modes and dialogue enhancement with a bass reduction option for nighttime viewing. Amazon.com had an offer at $248 on October 25, 2026.

What the maker puts in writing

  • “Feel every note with a 600W power output” and “Get the best seat in the house with 5.1ch real surround sound”
  • “Rear speakers deliver powerful surround sound to complete your home cinema experience”
  • “Effortless setup with easy color-coded connections”
  • “Connect to your TV via HDMI, Optical, or Analog connections”
  • “Select the sound or audio mode best suited to your entertainment with a push of a button”
  • “Fine-tune speech or reduce the bass for nighttime viewing with dialogue enhancement options”

It is the only product here that is both complete and simple

A soundbar system has no AV receiver and needs none. It connects straight to the television — HDMI, optical or analog, all three offered — and the amplification lives inside.

No separate box. No input switching. No setup menu.

And what makes this one unusual for a soundbar is that the surround is real: rear speakers deliver powerful surround sound. Two physical speakers behind the listener, rather than the psychoacoustic processing most bars use to imply surround from the front.

Against that, the rest of this shelf:

Speakers only, needing a receiver — Energy $275 · Klipsch Theater Pack $549.99 · Klipsch 5.1.4 $749.99 · R-620F pack $988.89 · R-625FA pack $1,298. The references show that receiver costing $474 to $502. Receiver included — Yamaha $499.99 · Energy+Denon $749 · Yamaha $749.95 · three Klipsch bundles from $1,299.98. Self-contained — this, and the Goldwood at $120.88.

Color-coded connections, which is the right kind of detail

Effortless setup with easy color-coded connections.

A 5.1 system has six leads to get right, and getting one wrong puts the center channel behind you or swaps the surrounds. Color coding is not a specification; it is the difference between a Saturday afternoon and a half-hour.

Worth setting beside the one other listing that thinks about installation: Yamaha’s YHT-5960U supplies “speaker wire perfectly matched for each speaker” — pre-cut to length per position, which solves the same problem the other way.

And the night mode addresses a real complaint twice

Fine-tune speech or reduce the bass for nighttime viewing with dialogue enhancement options.

Two halves of one problem.

Turn the volume down late at night and the first thing to go is dialogue — partly because quiet speech falls below the room’s noise floor, partly because human hearing is less sensitive to the extremes at low levels, so the balance shifts away from voices.

Enhancing dialogue lifts the band voices occupy. Reducing the bass stops explosions and music stings traveling through the floor to a sleeping household.

Nothing else on this shelf addresses listening level, apart from Yamaha’s YPAO room calibration, which is a different thing.

Six hundred watts, in context

Unqualified — neither RMS nor peak.

The shelf, read in order: Goldwood $120.88 claims 700 W · this $329 claims 600W · Yamaha YHT-5960U $749.95 claims 80-Watt · Onkyo TX-NR7100 claims 220W per channel at 6 ohms · Denon AVR-S670H claims 75W.

The eighty-watt figure is the honest one — a measured per-channel rating for a real AV receiver. Six hundred watts across a bar, a subwoofer and two rears is a system-total peak number.

And the weight cannot be right

454 g is exactly one pound, for a system of four separate pieces. A subwoofer alone — driver, magnet, cabinet, amplifier — runs several kilograms.

That is a placeholder, not a measurement. Expect something near ten kilograms.

What is not published

No driver sizes anywhere — not the bar, not the subwoofer, not the rears. Yamaha publishes every component’s dimensions; Goldwood publishes its satellite and subwoofer cabinet sizes.

No frequency response, where the Yamaha YHT-4950U publishes “28Hz/25kHz”.

No height channels. Four Klipsch products here have them, and the 5.1.4 at $749.99 has four — height from the front and the back.

No HDMI version or eARC, where the Yamaha YHT-5960U publishes “4K120AB and 8K60B HDMI 2.1 with HDCP 2.3 and eARC (4 in/1 out)”. On a bar that connects by HDMI, the version decides what a games console can do through it.

366 × 192 × 387 mm is published, evidently for one component.

In its favor, and against it

Strengths

  • Real rear speakers in a soundbar system, so the surround comes from behind rather than from processing
  • Color-coded connections and three ways to reach a television, which is the simplest setup here
  • A night mode that reduces bass as well as enhancing dialogue — two problems, one button

Compromises

  • Its catalog weight of 454 grams cannot describe a four-piece 5.1 system
  • Six hundred watts is unqualified, where the Yamaha YHT-5960U honestly publishes eighty
  • No driver sizes, no frequency response and no height channels

What gets asked most

How is this different from the other systems here?

It has no AV receiver and does not need one, and it is the only product on the shelf shaped that way. A soundbar system connects straight to the television — by HDMI, optical or analog, all three offered here — and the amplification lives inside. So there is no separate box, no input switching and no setup menu. What makes this one unusual for a soundbar is that the surround is real: "Rear speakers deliver powerful surround sound", which means two physical speakers behind the listener rather than the psychoacoustic processing most soundbars use to imply surround. Against that, five products on this shelf are speakers only and need a receiver costing $474 to $502 on top; four more include a receiver and all the wiring that implies. The only other self-contained system here is the Goldwood AA5170 at $120.88, which has an integrated amplifier in its subwoofer.

Can it weigh 454 grams?

No — that is exactly one pound, and it cannot describe this product. The system comprises a soundbar, a subwoofer and two rear speakers. A subwoofer alone, with a driver, a magnet, a cabinet and an amplifier, runs several kilograms; the bar adds more. Exactly 454 g (16 oz) is the signature of a placeholder rather than a measurement — a round imperial figure entered where a real one was missing. The other weights on this shelf read like measurements, with two exceptions of their own: Goldwood 20 lb (9.1 kg) (exactly 20.00 lb) · Klipsch Theater Pack 14,515 · Energy 18,053 · Yamaha 4950 23,496 · Yamaha 5960 24,494 · Energy+Denon 29,982 · Klipsch 5.1.4 66.1 lb (30 kg) (exactly 30 kg) · Klipsch+Denon 75,509 · R-620F pack 173.5 lb (78.7 kg). Expect something in the region of ten kilograms for a system of this kind.

What does the night mode actually do?

Two things at once, and the pairing is the clever part. The bullet publishes: "Fine-tune speech or reduce the bass for nighttime viewing with dialogue enhancement options." Those address the same complaint from opposite ends. Late at night you turn the volume down, and the first thing that becomes unintelligible is dialogue — partly because quiet speech falls below the room’s noise floor, and partly because human hearing is less sensitive to the low and high extremes at low levels, so the balance shifts. Enhancing dialogue lifts the band voices occupy. And reducing the bass stops the loud passages — explosions, music stings — from traveling through the floor to a sleeping household, which is the other half of watching something late. On this shelf only this listing and the Yamaha YHT-4950U’s YPAO system address the listening level at all.
