Onkyo added native Auro‑3D decoding via firmware updates in late 2023 to flagship models like the TX‑RZ70 and TX‑RZ50, enabling immersive height channels including the “Voice of God” layer. With robust Dirac Live room correction built-in (optional Bass Control), these units deliver precision-tuned 3D spatial sound in 11‑ or 13‑channel (e.g., 7.2.4/7.2.6) setups. Models like the TX‑RZ70 (THX‑certified, 140 W/ch, 11.2 channels) combine flagship performance, 8K HDMI 2.1, Atmos, DTS:X, IMAX Enhanced, and Auro‑3D. Auro‑Matic up‑mixing transforms stereo, 5.1, or 7.1 content into vertically immersive audio, though reviews note its performance varies room to room. The TX‑RZ70 is widely praised for offering “Auro‑3D + FREE Dirac Live” with leading measurements in its class—making Onkyo a strong choice for high-end immersive home theater.
