Assistrust KY2023 review

A 90 W soundbar with three equaliser presets and published checks on your television’s ports.

The closing call Sixty dollars and the only listing here that tells you what to check before buying — including that your television needs the dedicated ARC port, not any HDMI socket. It also lists wall mounting twice out of four placements.

What the maker puts in writing

  • “4 placing ways, 4 sound feels. Standing Tabletop: Stereo sound + Natural voice… Wall Mount: Heavy rumble for movie & game fun. Flat Tabletop: Balanced mid + Silky tone… Wall Mount: Clean bass + Sparkling treble”
  • “90W delivers Balanced bass + Clear crisp mid + Sparkling bright treble… Each volume press jumps 3 levels”
  • “Movie mode – Bold depth + Clear tone. Music mode – Lively vocal + Full melody. News mode – Natural speaking. 3 ready-to-use EQ presets”
  • “Important check before you buy: 1) Your TV must have ARC / OPT / AUX ports. 2) Use the dedicated ARC port, not regular HDMI. 3) Read full manual before first installation”
  • “Quick tip: Turn off Dolby or DTS audio in both your TV settings and the streaming app to ensure stable, clear audio output”

It is the only listing here that tells you what will go wrong

Two warnings, both correct, both absent from the other eleven listings on this shelf.

“Use the dedicated ARC port, not regular HDMI.” A television has three or four HDMI inputs and only one carries ARC — the Audio Return Channel, which sends sound out of the television back down the cable. It is marked “HDMI ARC” or “eARC” in small print beside the socket. Plug a soundbar into any other HDMI port and nothing happens, because ordinary inputs only receive.

“Turn off Dolby or DTS audio in both your TV settings and the streaming app.” Over ARC a television can send stereo PCM or a compressed bitstream. A bar that cannot decode the bitstream gets a stream it does not understand, and you get silence, static or dropouts.

Between them, those two paragraphs cover the great majority of soundbars that arrive and appear broken.

But the second warning is also an admission

If Dolby and DTS must be switched off, the bar decodes neither.

Which is fine at sixty dollars, and worth knowing against the alternative. Philips’s B5109 at $77.99 — eighteen dollars more — decodes Dolby Digital Plus and DTS Virtual:X, and publishes double the power.

Four placements, three positions

Standing Tabletop… Wall Mount… Flat Tabletop… Wall Mount.

Wall mounting is listed twice out of four, with two different sound descriptions and nothing said about what separates them.

The same slip is on its stablemate the KY-8000, which counts “horizontal” and “tabletop” as two of its four.

What is genuinely true underneath: a bar lying flat and a bar standing on edge do aim their drivers differently, and that honestly deserves two settings.

Ninety watts, and the number to distrust on this shelf

Ten of the twelve bars here publish a maximum or peak. This is one.

Only the Majority Sierra publishes RMS — 120 W continuous. Which means 120 W RMS is the more powerful bar than a “240 W peak” one, despite reading half as loud.

And Sony, Amazon and Bose publish no wattage at all.

What is not published

No subwoofer, so nothing below roughly 100 Hz. Hisense at $119.99 includes a wireless one; Suntrok at $81.21 a wired one.

No weight, and no driver count or size — where its own stablemate the KY-8000 states four drivers, and Suntrok publishes actual diameters (two 2.5-inch plus a 5.5-inch subwoofer).

No HDMI cable stated in the box, where Amazon, Hisense, Majority and Suntrok all include one.

Availability

At the check, the American Amazon store stood at roughly $60.

In its favor, and against it

Strengths

  • The only listing on this shelf that publishes what to check before buying, including the dedicated ARC port
  • Warns that Dolby and DTS must be switched off at the source, which is the commonest cause of silence
  • Bluetooth 5.3 and a three-level volume step, with paper and video instructions stated

Compromises

  • Lists wall mounting twice among four placements, with two different sound descriptions
  • Asking you to disable Dolby and DTS means it cannot decode either
  • No subwoofer, no weight and no driver size, where its own stablemate publishes four drivers

What gets asked most

Why does it tell me to switch Dolby and DTS off?

Because it cannot decode them, and saying so is more honest than most of this shelf. The bullet reads: "Turn off Dolby or DTS audio in both your TV settings and the streaming app to ensure stable, clear audio output." Here is the mechanism. Over HDMI ARC your television can send audio either as plain stereo PCM or as a compressed bitstream — Dolby Digital, DTS. A bar that cannot decode the bitstream receives a stream it does not understand and the result is silence, static or dropouts. Setting the television’s audio output to PCM or stereo fixes it. The listing publishing this is genuinely useful: it is the single commonest reason a new soundbar appears broken. Philips’s B5109 at $77.99 is the cheapest bar here that actually decodes Dolby Digital Plus and DTS Virtual:X.

What does the dedicated ARC port warning mean?

That not every HDMI socket on your television will work, and it is worth checking before the box arrives. The bullet is explicit: "1) Your TV must have ARC / OPT / AUX ports. 2) Use the dedicated ARC port, not regular HDMI." A television typically has three or four HDMI inputs and only one of them carries ARC — the Audio Return Channel, which sends sound *out* of the TV back down the cable to a soundbar. It is usually labeled "HDMI ARC" or "eARC" in small print beside the socket. Plug the bar into any other HDMI port and nothing happens, because ordinary HDMI inputs only receive. On older sets there may be no ARC port at all, in which case the optical output is the route. No other listing on this shelf mentions it.

Are there four placements or three?

The listing describes four and names three. Its words: "4 placing ways, 4 sound feels. Standing Tabletop: Stereo sound + Natural voice... Wall Mount: Heavy rumble for movie & game fun. Flat Tabletop: Balanced mid + Silky tone... Wall Mount: Clean bass + Sparkling treble, perfect for living room." Wall Mount appears twice, with two different descriptions of the sound, and the listing never says what distinguishes them — two orientations, two heights, nothing is stated. The same slip appears on its stablemate the KY-8000, which counts "horizontal" and "tabletop" as separate placements when they are the same position. What is real underneath: a bar lying flat and a bar standing on its edge do fire their drivers differently, and that is worth two settings.
