Design and Build
The Ultimea U2620 system adopts a conventional soundbar-and-satellite design language with a matte black finish intended to blend discreetly into a home entertainment setup. The main soundbar unit houses the central and front channel drivers, while the system is completed with two front satellite speakers and two rear satellite speakers, all connecting via wired connections to their respective main units. The inclusion of physical speakers for all channels is a key differentiator from systems that use virtual processing to simulate rear and side audio.
Build materials are listed as Acrylonitrile Butadiene Styrene (ABS) plastic and metal, suggesting a focus on durability and minimizing resonance. The system is designed for wall mounting, and a comprehensive wall-mounted kit is included in the box alongside all necessary cables for setup. The 6.5-inch wireless subwoofer provides the low-frequency foundation and can be placed independently within its wireless range for optimal bass response in the room. The overall design prioritizes function and integration over standout aesthetics, aiming for a clean, installed look.
Performance and Features
Audio Performance and Dolby Atmos
The core appeal of the Ultimea U2620 is its claim to deliver true 7.1 channel surround sound. With eight high-performance drivers distributed across the soundbar, satellites, and subwoofer, it creates a multi-directional sound field. The system employs Dolby Atmos decoding technology alongside proprietary algorithms like the SurroundX System and 360° Aural Spatial Localization Technology. According to the manufacturer, these technologies work together to dynamically adapt audio, placing specific elements in a three-dimensional soundscape around the listener rather than simply copying stereo signals to the surround speakers. This is intended to provide a genuine sense of audio objects moving overhead and around the room, enhancing immersion for movies and games.
Connectivity and Compatibility
Connectivity is handled through a combination of modern and legacy ports to ensure broad compatibility. The primary audio/video interface is a 4K HDMI pass-through with Enhanced Audio Return Channel (eARC), allowing for high-bandwidth, high-fidelity audio from compatible sources like modern gaming consoles and Blu-ray players, and simplifying connection to newer televisions. For devices without HDMI ARC, the system provides optical and 3.5mm AUX inputs. Wireless connectivity is offered via Bluetooth for streaming audio directly from smartphones or tablets. It is important to note that the manufacturer specifies the system does not support DTS audio decoding, which may limit playback of some legacy Blu-ray or streaming content encoded in DTS formats.
Software and Customization
A significant feature set is unlocked through the companion ULTIMEA Smart App. This app provides extensive control over the audio profile, far beyond what is typically available on a remote. Users can select from 121 expert-curated equalizer presets spanning various music genres like Bass, Pop, Classical, and Rock. Furthermore, six tailored EQ modes are offered for specific content types: Movie, Music, Voice, Sport, Game, and Night. The app also includes a 10-band professional equalizer and a “Customize” feature for manual fine-tuning. The app also facilitates Over-the-Air (OTA) firmware updates, allowing the system to receive new features and improvements post-purchase.
Setup, Support and Ownership
Setup involves connecting the main soundbar to the TV via the preferred cable (HDMI, optical, or AUX), placing the wireless subwoofer, and routing the wires for the front and rear satellite speakers to their connection points on the soundbar and subwoofer respectively. The inclusion of all necessary cables—HDMI, optical, stereo RCA, and a 20-foot stereo RCA cable for the rear speakers—means everything needed for a basic installation is in the box. The wall mount kit provides an alternative to shelf placement. The wireless pairing process for the subwoofer is noted in user feedback as requiring a specific simultaneous button press on the remote and the subwoofer itself.
Ownership support includes a one-year warranty. The ULTIMEA Smart App’s OTA update functionality is designed to extend the product’s lifecycle by adding features and addressing issues. However, based on user review excerpts, some customers have reported challenges accessing customer support, citing difficulty reaching a live agent via phone. The manufacturer provides standard troubleshooting steps, but the availability of direct support appears to be a point of consideration for prospective buyers.
What Owners Say
Owner feedback, reflected in the rating distribution, shows a largely positive reception, with the majority of reviews being highly favorable. Long-term users praise the system’s reliability and significant audio improvement over basic TV speakers and smaller soundbars, noting the clear and immersive surround effect and the powerful contribution of the subwoofer. Several reviews highlight that the system delivers performance exceeding expectations for its price point, offering a tangible step up from virtual surround systems.
Common points of praise include the impactful bass, the genuine sense of surround sound from the physical speakers, and the high maximum volume capabilities. Critical feedback from a minority of users centers on occasional connectivity issues between the soundbar and TV, the wired nature of the satellite speakers (which are not fully wireless), and the aforementioned challenges with customer support accessibility. A consistent theme in critical reviews is the acknowledgment of the product’s value but frustration when technical issues arise.

This system is not the best fit for users who demand a completely wireless, clutter-free setup, as the satellite speakers require physical wires. Those with extensive media libraries in DTS audio formats may find the lack of support limiting. Individuals who prioritize immediate and easily accessible phone support for troubleshooting may want to consider alternatives. Finally, if your primary need is crystal-clear dialogue enhancement, a soundbar specifically optimized for voice clarity might be a more targeted choice, as covered in our roundup of the best TV soundbars for voice clarity.
Final Verdict
The Ultimea U2620 makes a compelling case for itself in the crowded audio market by focusing on a tangible differentiator: real, physical surround sound channels paired with Dolby Atmos processing. It successfully creates an enveloping audio environment that virtual surround systems often struggle to match authentically. The powerful wireless subwoofer and the extensive customization offered by the smart app add significant value, allowing users to tailor the sound precisely for movies, music, or gaming. For its category, it represents a feature-rich package aimed at delivering a cinematic experience.
However, its value proposition comes with clear trade-offs. The wired satellite speakers demand a commitment to cable management, and the absence of DTS support is a notable omission for some media formats. Prospective buyers must weigh the impressive performance and customization against these limitations and the reported variability in customer support access. For those seeking an immersive, customizable, and powerful audio upgrade centered on true multi-channel sound without a premium price tag, the Ultimea U2620 is a noteworthy contender.

FAQs
Does the Ultimea U2620 have up-firing speakers for Dolby Atmos?
No, based on the manufacturer specifications and user reviews, the Ultimea U2620 (Poseidon D80) does not include dedicated upward-firing drivers. It creates its Dolby Atmos and three-dimensional sound effect through its array of front, center, and surround speakers combined with proprietary audio processing algorithms like the 360° Aural Spatial Localization Technology. The system aims to simulate overhead audio cues through this processing and speaker positioning rather than using physical upward-firing units.
Can the rear speakers connect wirelessly?
No, the rear satellite speakers are not wireless. According to the product details and user feedback, the two rear speakers connect to the wireless subwoofer unit via included wired cables (a 20-foot stereo RCA cable is provided). The subwoofer itself connects wirelessly to the main soundbar, but the satellite speakers require physical wire runs to the subwoofer’s location.
What is the difference between this and virtual surround sound systems?
The key difference is the use of physical speakers for each channel. A true 7.1 system like the Ultimea U2620 uses distinct speakers placed around the room (front left/right, center, surround left/right, rear left/right) to produce sound from specific directions. Virtual surround systems, often found in simpler soundbars, use fewer physical speakers and advanced digital signal processing to trick the ear into perceiving sound coming from around you. The U2620’s approach generally provides more precise and reliable directional audio cues.
How does the app enhance the experience compared to just using the remote?
The ULTIMEA Smart App provides a far greater level of control and customization than the included remote. While the remote offers basic functions like power, volume, and input selection, the app unlocks access to 121 genre-specific EQ presets, six tailored sound modes (Movie, Music, etc.), a 10-band professional equalizer for manual adjustment, and a custom mode for personal fine-tuning. The app is also the conduit for firmware updates, ensuring the system can gain new features over time.
