Quick Take
The TX-RZ30 is a home-theater heavy hitter: big, room-filling sound with true 3D immersion (Dolby Atmos), smart room tuning (Dirac Live), and easy multiroom tie-in with Sonos. It’s made for people who want “wow” from movies, music, and games in a medium-to-large room. The trade-offs? Setup takes patience (Dirac measurements aren’t a 5-minute job), the chassis is on the chunky side, and the deep feature set comes with a learning curve. If you’re willing to spend an evening dialing it in, the payoff is absolutely worth it.

9.2-Channel Surround with Serious Power
The TX-RZ30 drives nine amplified channels and supports two independent subwoofer outputs (9.2). Power is rated 100 W/ch into 8 Ω (20 Hz–20 kHz, 0.08% THD, 2 channels driven), with 170 W/ch into 6 Ω (1 kHz, 1% THD, 1 ch IEC) for headroom. That’s plenty for medium-to-large rooms with properly matched speakers.
Dirac Live Room Correction — Out of the Box
Dirac Live (Full Bandwidth) measures your room and corrects frequency and timing issues so your speakers and subs play cleanly in your space. Dirac Live Bass Control is available as an optional upgrade for more precise multi-sub integration.
Dolby Atmos, DTS:X & IMAX Enhanced
Object-based formats place effects above and around you (think 5.2.4 or 7.2.2 layouts). IMAX Enhanced certification aligns performance to IMAX’s standards for compatible content.
Works with Sonos
“Works with Sonos” enables integration with a Sonos Port (sold separately) including volume passthrough, so your AVR joins a multi-room Sonos system while retaining Onkyo’s amplification and processing.
Modern HDMI & Gaming Features
You get 6 HDMI inputs / 2 outputs (eARC) with 8K/4K Ultra HD support and HDMI 2.1a features including VRR, ALLM, QFT, and SBTM—great for next-gen consoles and PCs. HDR formats include Dolby Vision and HDR10+.
Built-In Streaming & Ecosystem
Roon Tested, Chromecast built-in, AirPlay 2, Spotify, Amazon Music HD, TIDAL, Deezer, and TuneIn are supported—so music is covered right out of the box.
Sound Quality and Usability: What Customers Say
The Onkyo TX-RZ30’s sound quality has received raving reviews from a broad base of users. Customers applaud the clear, dynamic audio and the receiver’s ability to deliver detailed highs without sounding shrill, alongside bass that’s powerful but never overwhelming. Many highlight how well Dirac Live works to smooth out room imperfections—though some note that the setup process requires patience and a bit of technical know-how.
The inclusion of Dolby Atmos and IMAX Enhanced certifications has been widely praised for transforming the home theater experience. Viewers feel genuinely immersed, often citing the three-dimensional soundstage as a game-changer compared to traditional surround sound systems.
On the practical side, the usability of the TX-RZ30 has a mixed bag of feedback. While tech-savvy users appreciate the depth of customization options, beginners sometimes find the menus and calibration process a bit overwhelming. The bulkier chassis also demands more space than some compact setups can offer.
Connectivity and integration with Sonos Certified devices are frequently praised for bringing modern convenience to a serious AV receiver, creating a bridge between classic high-end audio setups and sleek wireless streaming.
