ULTIMEA Poseidon D80 U2620 7.1 Soundbar with Dolby Atmos and Wireless Subwoofer

Practical tips

The 7.1-channel format brings a soundbar, four wired surround speakers and a 6.5-inch wireless subwoofer together for home theatre audio. Place the two front and two rear speakers around your listening area to make use of the system’s multi-directional sound. For a room-based setup, ULTIMEA recommends the Poseidon D80 for spaces of 30–50 m².

Connect a compatible TV through HDMI eARC, or use the optical or AUX input with other equipment. The system also has Bluetooth, plus one HDMI input and one HDMI output with 4K support for a connected device setup. Wall-mounting hardware is included, giving you another way to arrange the soundbar and speakers in your room. The subwoofer connects wirelessly, while the four surround speakers are wired, so plan their placement around your seating and room layout.

What stands out

Dolby Atmos and ULTIMEA’s SurroundX system with 360° Aural Spatial Localization Technology are designed to position sound around the room, rather than keeping the experience focused at the front. That can add a more enveloping audio presentation for films and streaming shows, while the separate front and rear speakers help create a wider soundstage. The 460W maximum output and 6.5-inch subwoofer make this a full home theatre system, not just a bar for improving TV dialogue.

Control the system with buttons or the ULTIMEA app, where you can customize settings and receive over-the-air updates. For everyday use, that means you can adjust the system from your phone as well as from the unit itself. It also suits gaming setups: HDMI eARC and the HDMI input provide options for connecting a TV and gaming console, with optical and AUX available for other devices. Note that the Poseidon D80 does not support DTS decoding, which matters if DTS decoding is required for your audio setup.

Buyer feedback often praises the sound separation and straightforward setup, including the wall-mounting brackets. Some buyers also report units developing functional problems after a few months, so reliability is a point raised in customer feedback.

Key takeaways

Choose the Poseidon D80 if you want a multi-speaker surround arrangement with Dolby Atmos, app control and several ways to connect your home entertainment devices. It suits a different need from a simple stereo soundbar: the four wired surround speakers are intended to bring sound to the front and rear of the listening area, while the wireless subwoofer adds a separate low-frequency speaker to the system. For a practical example, connect a TV through eARC, position the four surround speakers around the seating area, then use the app to adjust your preferred settings for a movie or gaming session. Its recommended room size is 30–50 m², and the mounting kit supports a wall-mounted arrangement.
