Best for Affordable multi-channel surround in small to mid-sized rooms
This system provides physical rear satellite speakers and a dedicated subwoofer, resolving the spatial flat spots common to single-chassis soundbars. While Atmos decoding is supported, height effects are virtualized and will not match true overhead physical drivers. Nevertheless, it represents an effective entry path to real multi-channel surround at a competitive price.

Side-firing drivers cannot match the positional accuracy of physical satellite units
The Ultimea Poseidon M60 centers on a compact soundbar housing five full-range drivers, augmented by an external wired subwoofer. The main bar is configured for tabletop or wall-mounted placement beneath a television, while the subwoofer utilizes a 5.3-liter wooden cabinet to minimize cabinet resonance. The specification sheet presents a conflict regarding the low-frequency driver, listing both an 18-millimeter figure and a 5.25-inch woofer diameter; buyers should treat 5.25 inches as the cone diameter and 18 millimeters as the excursion depth. Build materials rely primarily on matte plastics for the bar enclosure and dense MDF for the subwoofer housing. Connecting the subwoofer requires a physical tether to the soundbar, which restricts placement options compared to 2.4 GHz wireless alternatives. However, the wired design eliminates synchronization dropouts. At this price point, the integration of five forward and side-firing drivers within a rigid wooden-subwoofer pairing represents a structured approach to entry-level acoustic packaging.
Real-world performance
Acoustically, the system is rated for 300 watts peak power across an operating range of 45 Hz to 18 kHz, achieving a maximum sound pressure level of 99 dB. Processing handles Dolby Atmos streams via HDMI eARC, relying on two side-firing transducers rather than physical overhead or satellite speakers to widen the soundstage. While lateral reflections expand the field beyond the TV frame, they cannot replicate the precise spatial localization of discrete surround hardware. Vocal clarity is reinforced by the VoiceMX DSP algorithm, which separates mid-band speech frequencies from low-frequency effects. Dialogue remains intelligible during dynamic film scoring without forcing excessive volume shifts. The wired subwoofer fills out lower octaves down toward its 45 Hz threshold, providing adequate percussive impact for television content, though it lacks the sub-bass extension required for deep cinematic rumble. Latency remains below 0.5 milliseconds, avoiding lip-sync drift during high-bitrate playback.
Value for money
Priced at $158.58, the Poseidon M60 operates in an entry-tier bracket where compromises are routine. However, Ultimea equips the unit with features rarely standard at this cost, notably an HDMI eARC port capable of 37 Mbps bandwidth and Bluetooth 5.4. Most soundbars under $200 limit users to optical or basic HDMI ARC, truncating lossless audio pass-through. Furthermore, the accompanying mobile application supplies a ten-band graphic equalizer, 121 preset configurations, and 13 surround intensity steps, offering significant parametric control over the factory acoustic profile. With an aggregate rating of 4.4 out of 5 across 2,693 customer evaluations, the market reception reflects high satisfaction relative to expenditure. While the system does not produce true discrete 5.1 spatialization due to its all-in-one bar chassis, the inclusion of eARC, solid amplification levels, and extensive EQ compensation delivers strong measurable utility per dollar spent.
Who should skip it
Prospective buyers seeking an uncompromised multi-channel home theater should look elsewhere. Because the system simulates a 5.1-channel Dolby Atmos environment using only the central soundbar and a subwoofer, it cannot match physical satellite speakers for rear directional effects. Viewers in large rooms with open floor plans or vaulted ceilings will experience diminished surround cues, as the side-firing drivers require adjacent boundary walls to bounce acoustic energy effectively. Dedicated home theater builders demanding sub-30 Hz infrasonic bass will also find the 5.25-inch, 45 Hz floor insufficient for tactile cinematic weight. Furthermore, users who require a completely wire-free floor setup will be frustrated by the tethered cable linking the subwoofer to the soundbar. If your living space cannot accommodate boundary-dependent reflection or if you require genuine height channels, an AV receiver with discrete passive speakers remains the necessary, albeit more expensive, pathway.

Common questions
Does the Ultimea Poseidon M60 include physical rear surround speakers?
No. The Poseidon M60 achieves its 5.1-channel Dolby Atmos reproduction using five drivers positioned entirely within the main soundbar alongside the wired subwoofer. Two side-firing drivers bounce sound off side walls to create lateral breadth, but no separate physical speakers are placed behind the seating position.
What explains the contradictory 18 mm and 5.25-inch woofer specifications?
The specification sheet lists both dimensions due to a common labeling ambiguity. The 5.25-inch measurement represents the actual cone diameter of the low-frequency driver, whereas the 18 mm figure refers to driver excursion depth or voice coil dimensions. Bass output corresponds to a conventional 5.25-inch wooden subwoofer unit.
How should the system be connected to achieve Dolby Atmos playback?
Dolby Atmos requires connecting the soundbar to your television via the supplied HDMI eARC port using a high-speed HDMI cable. While optical and Bluetooth 5.4 connections are supported for general audio, they lack the data throughput required to decode uncompressed Dolby Atmos multi-channel bitstreams.
Can the subwoofer be placed anywhere in the room wirelessly?
No. The subwoofer connects to the primary soundbar via a physical audio cable. Placement is constrained by the length of this supplied wire. While this guarantees zero wireless interference or latency, buyers must ensure an unobstructed pathway between the soundbar and the intended subwoofer location.
How we judge projectors & home theater
Rule 01
ANSI lumens are comparable; 'light source lumens' are not.
Rule 02
Contrast and black level matter far more than resolution claims.
Rule 03
Match screen gain and ambient-light rejection to projector throw and room lighting; there is no universal improvement multiplier.
