The ULTIMEA Skywave F40 Boom 5.1.2 Channel Soundbar with Dolby Atmos delivers an immersive home theater experience with up-firing drivers, dual surround speakers, and a powerful subwoofer. SurroundX™ 360° Audio creates a realistic 3D sound field, while BassMX technology delivers deep, precise bass down to 40Hz. HDMI eARC ensures lossless audio transmission, and the Ultimea App allows full control with a 10-band EQ, level adjustment, and OTA updates.

  • 5.1.2ch Surround Sound System: A 5.1.2-channel system featuring up-firing speakers, surround sound, and a powerful subwoofer creates lifelike, multidimensional audio. Feel the Sky Around You—raindrops falling from above, helicopters circling overhead, thunder rumbling in all directions. Sound isn’t just around you, it engulfs you, as if the ceiling disappeared. This is Dolby Atmos: not just heard, but felt.
  • Up-Firing Drivers with Neodymium Core: The up-firing channels use neodymium internal magnets and 18-core large voice coils to enhance height precision and vertical throw. This aerospace-grade configuration ensures better high-frequency dynamics, delivering focused and elevated sound images that unlock the true potential of Dolby Atmos.
  • 360° SurroundX Audio: SurroundX technology combines two rear surround speakers and dual up-firing Atmos drivers to build a true 360° sound field. Powered by intelligent spatial algorithms, the system precisely positions audio around and above you—enhancing Dolby Atmos with a more natural, three-dimensional soundstage.
  • Lossless Audio Transmission: Unlock full Dolby Atmos performance with HDMI eARC, supporting up to 37Mbps bandwidth for lossless 5.1.2-channel audio. Compared to regular ARC, eARC delivers richer detail and better surround effects with no compression. With CEC, your TV and soundbar work as one—power, volume, and input sync automatically for effortless control.
  • Advanced App Control: Customize every detail of your audio experience with the Ultimea App. Fine-tune your surround sound with 13-step level adjustment (-6 to +6), optimize with a 10-band graphic EQ, and choose from 121 preset sound settings. Enjoy seamless OTA updates that unlock new features and keep your system performing at its peak.
