Speakers Ultimea Poseidon D80 Black 7.1 channels, 8 speakers, wired & wireless, active subwoofer

Ultimea Poseidon D80 Black delivers 7.1-channel surround sound with Dolby Atmos processing and 360° aural spatial localization to create a wide, immersive soundstage. The system includes eight finely tuned drivers and an active subwoofer with 16 mm diaphragm excursion, offering up to 33% more bass compared to the previous Poseidon D80. It supports 4K HDR passthrough, HDMI eARC/HDMI IN, wired and Bluetooth 5.3 wireless connectivity, and provides smart app control and multiple equalizer modes for flexible audio adjustment.

Advantages

Dolby Atmos and SurroundX algorithms expand the rear sound field and improve spatial accuracy for a more realistic listening experience. Eight high-density drivers ensure precise signal response suitable for high-sample-rate audio, while the active subwoofer and BassMX technology deliver deeper, clearer low frequencies. X-Upmix converts non-Dolby sources into multi-channel output, and 4K HDR passthrough with HDMI eARC preserves video and audio quality for home cinema setups.

Suitable for

• Home cinema systems requiring immersive 7.1 Dolby Atmos sound
• Gaming setups where positional audio and multiple EQ modes matter

How to use

Place the main units and surround speakers according to a standard 7.1 layout to achieve optimal spatial imaging; position the active subwoofer where bass response is balanced in the room. Use the smart app or on-device controls to select equalizer modes (Game, Movie, Music, Night, Sport, Voice) and adjust volume, bass, and surround levels.

Recommendations

For best surround performance, calibrate speaker positions and levels in your listening room, enable Dolby Atmos and X-Upmix when using stereo or non-Dolby sources, and allow a short break-in period for the drivers to reach their optimal response. Use HDMI eARC for highest-quality audio when connecting modern TVs and receivers.
