ULTIMEA Poseidon M60 Review A Practical Look at the 51 Channel Dolby Atmos Sound Bar System
Why This Product Is Worth a Look
Built in TV speakers often struggle with quiet dialogue, bass, and room filling sound. The ULTIMEA Poseidon M60 is designed to address those problems with a compact 5.1 channel soundbar, Dolby Atmos processing, and a separate wired subwoofer. It is worth considering if you want a broader, more powerful presentation without placing speakers behind your sofa.
Product Overview
The ULTIMEA 5.1CH Surround Sound Bar System with Dolby Atmos, Poseidon M60 is a home theater system intended for small to medium size rooms. This review focuses on the U3721 version, which is rated for up to 300 watts of peak output.
The system combines five 2.25 inch full range drivers inside the soundbar with a 5.25 inch subwoofer in a tuned wooden cabinet. Two of the soundbar drivers fire toward the sides to create a wider soundstage. Since there are no physical rear speakers or upward firing drivers, surround and height effects are produced virtually.
Connectivity includes HDMI eARC, optical, USB, and Bluetooth 5.4. The Ultimea mobile app adds a 10 band equalizer, 121 sound profiles, several listening modes, adjustable surround levels, and firmware updates. VoiceMX is included to improve speech clarity, while BassMX provides control over the subwoofer response.
This system is primarily suited to television viewing, movies, casual gaming, sports, and everyday music playback. Its compact layout may be especially appealing to people who want stronger sound without running wires to rear speakers.
Design, Build, and Everyday Feel
The Poseidon M60 has a simple black finish with a fabric covered front and a low profile shape. At approximately 31.5 inches wide, 3.54 inches deep, and 2.76 inches tall, it should fit below many televisions without covering the lower part of the screen. Wall brackets and mounting hardware are also included.
To reduce the size of the packaging, the soundbar arrives in two sections. These pieces align and twist together during setup. The completed bar feels visually cohesive, although the dividing seam remains visible in the center. Controls are positioned on the top surface, while LED indicators on the front show input and operating status.
The separate subwoofer uses a wooden enclosure and has a narrow footprint. This should make it relatively easy to place beside a television stand, sofa, or table. However, it connects to the soundbar with a cable measuring approximately 9 feet 5 inches, so placement is less flexible than it would be with a wireless subwoofer.
The package includes the soundbar, wired subwoofer, power adapter, HDMI cable, remote control, wall brackets, and mounting hardware. Batteries for the remote are not included. The matte surfaces should be reasonably easy to maintain, but the system is not water resistant and should be kept away from moisture.
Key Features
Virtual 5.1 Channel Dolby Atmos Sound
Five drivers inside the main bar reproduce the left, center, right, left surround, and right surround channels. The side firing drivers spread effects beyond the television, while Dolby Atmos processing adds spatial information. This can produce a wider and more enveloping presentation than typical TV speakers. However, it cannot provide the same rear separation or overhead precision as physical rear and upward firing speakers.
VoiceMX Dialogue Enhancement
VoiceMX focuses on the vocal frequency range and uses digital processing to make speech easier to distinguish from music and sound effects. This can be useful for movies with quiet conversations, sports commentary, and online videos with uneven audio. Strong settings may make voices sound overly prominent or slightly processed, so moderate adjustment may provide a more natural result.
BassMX and Wired Wooden Subwoofer
The 5.25 inch subwoofer uses a tuned 5.3 liter wooden enclosure and a high excursion driver to add weight to explosions, engines, and music. BassMX allows the low frequency output to be adjusted for different rooms. The compact cabinet is convenient, but the wired connection limits placement, and the default bass level may be excessive in a small room or near a corner.
App Based Sound Customization
The Ultimea app provides a 10 band graphic equalizer, 121 sound profiles, and 13 surround level adjustments. It also offers Movie, Music, Voice, Sport, Game, and Night modes. These controls are valuable because the soundbar may sound somewhat thin through the lower midrange with its default settings. The app also handles over the air firmware updates, which should be completed only when the system has stable power.
HDMI eARC and Bluetooth 5.4
HDMI eARC is the preferred television connection because it supports Dolby Atmos, higher bandwidth audio, and HDMI CEC control. Bluetooth 5.4 provides a convenient option for streaming from a phone or tablet. Optical and USB are also available. The main limitation is that there is only one HDMI port, so consoles and media players must normally connect through the television.

What It May Be Like to Use
Based on the available product information and documented user experiences, assembly should be straightforward. The two soundbar sections need to be joined, the subwoofer connects to the dedicated SUB OUT port, and the included HDMI cable connects the soundbar to a television’s eARC port.
In typical daily use, the most immediate improvements over built in television speakers are likely to be clearer speech, stronger bass, and a soundstage that extends farther to the sides. The 300 watt figure is a peak rating rather than continuous output, but the system should still provide sufficient volume for many bedrooms and small to medium living rooms.
The surround presentation should be approached with realistic expectations. Effects may feel broader and more atmospheric, especially in Movie mode with XupMix enabled, but sounds intended to come from directly behind the listener will not be as precise as they would be with separate rear speakers. Dolby Atmos height effects are also likely to be subtle because there are no dedicated upward firing drivers.
Tonal balance may require adjustment. Available reports indicate that the soundbar can sound thin or hollow through the lower midrange, while the subwoofer may be too prominent in a small room. Spending a few minutes with the app equalizer can improve integration between the bar and subwoofer, although it may not completely remove the difference.
What Works Well
Dialogue clarity is a major strength. VoiceMX can help speech remain understandable during busy action scenes and at lower listening levels.
The compact subwoofer adds meaningful low frequency impact without requiring a large amount of floor space.
The side firing drivers create a noticeably wider presentation than most built in television speakers.
The app provides unusually extensive adjustment for this type of compact system. The 10 band equalizer and multiple presets make it easier to adapt the sound to different rooms and content.
HDMI eARC supports Dolby Atmos and can allow the television remote to control volume through HDMI CEC.
Bluetooth 5.4 is useful for convenient music streaming from compatible phones and tablets.
The included HDMI cable and wall mounting hardware reduce the number of accessories needed for a basic installation.
Things to Consider
This is virtual surround rather than a traditional system with speakers behind the listening position. Rear effects will have limited directional separation.
There are no upward firing drivers, so overhead Dolby Atmos effects may not sound distinctly above the listener.
The subwoofer is wired. Its cable provides some positioning range, but it is less flexible than a wireless design.
The Poseidon M60 does not natively decode DTS. DTS sources must be converted to Dolby or PCM by the television, console, disc player, or media device.
There is only one HDMI eARC port, and it is intended for the television connection. The soundbar cannot serve as a multi-input HDMI switch.
There is no 3.5 millimeter analog input. Desktop computers without optical output or compatible Bluetooth may require an adapter or another connection method.
Some voices and instruments may lack warmth because of the system’s lower midrange balance. Equalizer adjustments can help, but listeners who prefer a naturally full sound may want to consider alternatives.
Firmware and HDMI CEC behavior can vary depending on the television and software version. Reports of power cycling and update related startup problems suggest that updates should be performed carefully.
Who Is This Product For?
The Poseidon M60 is a reasonable option for someone using a television in a bedroom, apartment, gaming area, or small to medium living room. It is particularly relevant for viewers who prioritize clear dialogue, adjustable bass, simple installation, and a wider soundstage without rear speaker clutter.
It may also work well for people who enjoy changing sound settings for movies, games, sports, and late night viewing. The app offers more control than many basic soundbars.
It may not be the right choice for home theater enthusiasts who want precise rear effects, convincing overhead sound, native DTS decoding, multiple HDMI inputs, or wireless subwoofer placement. Listeners who want warm, balanced sound without using an equalizer should also keep the reported midrange character in mind.
Helpful Tips Before You Buy
Confirm that the listing is for the U3721 Poseidon M60 rated at 300 watts peak. ULTIMEA also offers related versions with different model numbers and power ratings.
Check whether your television has HDMI eARC or ARC. For the best available Dolby Atmos support, use eARC and set the television audio output to Passthrough or Auto.
Connect gaming consoles and media players to the television because the soundbar does not include additional HDMI inputs.
If a movie or disc uses DTS, configure the source device to convert it to Dolby or PCM. The M60 will not decode DTS directly.
Allow enough space for the subwoofer cable and keep the cabinet’s driver and vents unobstructed. Placing it close to a corner may increase bass substantially.
Start with moderate VoiceMX and bass settings. Excessive voice enhancement can sound unnatural, while too much bass can overwhelm a small room.
Use the 10 band equalizer to add some midrange presence and reduce excessive low frequencies if the default sound feels unbalanced.
Make sure the system has stable power before beginning an app based firmware update. Do not disconnect the soundbar while an update is running.
If unexpected power cycling occurs, try disabling Auto Standby in the app or adjusting the television’s Quick Start and HDMI CEC settings.
Common Questions
Does the Poseidon M60 include rear speakers?
No. All five main channels are built into the soundbar. Two side firing drivers help create virtual surround effects, but there are no physical speakers behind the listener.
Does it support real Dolby Atmos?
It can receive and process Dolby Atmos through HDMI eARC. However, because it lacks upward firing speakers, the height effect is virtual and may be subtle.
Is the subwoofer wireless?
No. The subwoofer connects to the soundbar through a dedicated cable. This avoids wireless pairing but reduces placement flexibility.
Can it play DTS audio?
It does not natively decode DTS. The source device or television must convert DTS content to Dolby or PCM.
Can the Poseidon M60 connect to a computer?
It can connect through Bluetooth or optical when supported. There is no 3.5 millimeter analog input, so some desktop setups may require an adapter.
Can the television remote control the volume?
In many compatible setups, yes. HDMI CEC through the eARC connection can provide unified volume and power control, although behavior depends on the television.
Final Thoughts
The ULTIMEA Poseidon M60 offers a practical upgrade over basic television speakers, especially when dialogue clarity, stronger bass, and a wider soundstage are the main priorities. Its compact two piece bar, narrow wooden subwoofer, HDMI eARC support, and detailed app controls make it adaptable to many smaller entertainment spaces.
Its limitations are equally important. Surround effects are virtual, overhead positioning is modest, the subwoofer is wired, and DTS is not supported. The soundbar may also need equalizer adjustment to address a thin lower midrange and strong default bass.
For a small or medium room where simplicity matters more than precise rear and height effects, the Poseidon M60 is a capable and flexible option. It will be most rewarding when connected through HDMI eARC, configured for passthrough audio, and tuned through the Ultimea app to match the room.
