ULTIMEA Poseidon M60 vs LG S40TR: Which Setup Fits Your TV Room?

Choose first by where you can place speakers: ULTIMEA describes left and right surround speakers built into the M60 bar, while LG describes separate S40TR rear speakers that need a wire between them and AC power at one speaker. Then check your TV: LG’s one-remote and WOW Orchestra features are limited to select LG TV and soundbar models. The published feature lists do not establish which system sounds better.

The buying question

Should you choose the M60’s built-in left/right surround layout or the S40TR’s separate rear speakers, and does the S40TR’s limited LG-TV integration fit your setup?

The M60 puts its listed left and right surround speakers in the main bar; the S40TR uses separate rear units with a cable between them and AC at one unit, plus TV-linked features that only work with select LG models.

Quick verdict

Choose LG S40TR 4.1-channel Home Theater Soundbar if

  • You can place the S40TR rear units, connect the wire between them and supply AC power to one, and your exact LG TV is among the models that support the TV-linked features you want.

Choose ULTIMEA Poseidon M60 5.1 Soundbar if

  • You prefer the published M60 layout, with its left and right surround drivers built into the soundbar, instead of separately placed rear units.

When the recommendation changes
  • If the exact LG TV model is not on the compatibility list for the feature you want, remove that integration benefit from the S40TR decision.
  • If the M60’s separate subwoofer or exact package/setup requirements do not fit your room, reassess the layout choice before buying.

The differences that matter

Surround Speaker Layout And Rear Power Cabling For Room Fit

LG S40TR 4.1-channel Home Theater Soundbar

S40TR includes separate rear speakers; LG says they require a wired connection between them and one rear speaker requires AC power.[1]

ULTIMEA Poseidon M60 5.1 Soundbar

ULTIMEA describes one bar with built-in left/right surround speakers and separately lists a subwoofer.[2]

What this changes: The layout changes where speakers can be placed and which rear-unit cable/power connections a buyer must plan for; it does not establish a sound-quality advantage.[1, 2]

The better fit depends on your priorities

Tv Control And Supported Lg Tv Integration

LG S40TR 4.1-channel Home Theater Soundbar

LG lists one-remote control, WOW Orchestra and three-band equalizer customization; it limits the first two features to select LG TV and soundbar models.[1]

ULTIMEA Poseidon M60 5.1 Soundbar

ULTIMEA lists app control, HDMI eARC and CEC device sync for Poseidon M60.[2]

What this changes: The S40TR TV-linked benefits depend on exact model compatibility, while the M60 page lists app and eARC/CEC control routes. The listed features do not establish compatibility with every TV or whether the two control options offer the same functions.[1, 2]

The better fit depends on your priorities

Best for your routine

A room where separate rear-speaker placement and the listed inter-speaker wire/AC connection are practical

Best fit: LG S40TR 4.1-channel Home Theater Soundbar

Based on listed features, not comparative testing.

The S40TR is the option here with separate rear units; choose it for that layout only if the room can accommodate the stated wiring and power, and if any desired LG-TV integration is confirmed.

A room where the buyer prefers the left and right surround speakers built into the main bar

Best fit: ULTIMEA Poseidon M60 5.1 Soundbar

Based on listed features, not comparative testing.

ULTIMEA describes the M60 surround speakers as built into the soundbar. This favors that configuration for buyers who want those drivers at the bar; it does not prove a better listening result.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Price was not assessed for this comparison. Decide first whether the speaker placement and TV-control conditions fit your room; compare current offers separately.

Offers and price history were not assessed; no buy-timing guidance is provided.

Limitations

  • This comparison provides no comparative listening measurements for sound quality, dialogue clarity, surround localization, room coverage or latency.
  • The manufacturer page names Poseidon M60 but does not display a model code. Confirm the exact US package and setup requirements for your room; the details used here do not establish every cable or accessory in the retail box.
  • LG says one-remote control and WOW Orchestra are limited to select LG TV and soundbar models. Check the exact TV model and feature before purchase.
  • Confirm the exact M60 package and setup requirements for your room. Its product page lists a separate subwoofer; the available comparison does not establish every cable or accessory in the exact US retail box.

Questions shoppers ask

Does the LG S40TR rear-speaker setup have no wires?

No. LG describes the rear speakers as wireless in their connection to the soundbar, but its footnote says a wire is required between the rear units and one unit needs AC power. Plan for those connections.

Will WOW Orchestra or one-remote control work with any LG TV?

No. LG says these features are available only with select LG TV and soundbar models. Check the exact TV model’s compatibility before buying for those features.

Does the M60 use separate rear speakers?

ULTIMEA describes the M60 as one bar with built-in left and right surround speakers. The same product page lists a separate subwoofer, so the published layout is not a single-piece system.

Methodology and sources

Compared the named-model manufacturer pages for speaker placement, stated rear-speaker connection and power conditions, published app/eARC/CEC options, and LG’s select-model TV restriction. No controlled listening or room test was performed.
