Verdict

The Marantz Grand Horizon is a luxury wireless speaker featuring a circular design wrapped in eco-fiber fabric on a marble base, though it lacks battery power for true portable portability due to its substantial 46.9 lb weight. It is engineered with an 8-driver array consisting of one 8-inch subwoofer, four 3-inch midrange drivers, and three 1-inch silk dome tweeters, delivering a frequency response of 28 Hz to 20 kHz and a maximum SPL of 111 dB. Driven by 370W RMS of proprietary Marantz Rise GaN FET amplification and managed by Mirage DSP, its core performance pros include immersive virtual Dolby Atmos playback, high-res audio streaming up to 24-bit/192kHz via the HEOS platform, and rich physical inputs like HDMI eARC, optical, and RCA. Key drawbacks include its extremely high price tag, high power consumption, and the lack of advanced Bluetooth codecs as it only supports standard SBC format.

Third-party reviews

What customers like about Marantz Grand Horizon?

  • Stunning high-end luxury design featuring premium materials like a natural marble plinth and eco-fiber fabric made from recycled ocean plastics.
  • Powerful, room-filling sound with a massive 370W output that easily compensates for the lack of separate speakers.
  • Excellent acoustic performance with clear treble, refined detail, and incredibly deep, tight bass response.
  • Versatile multi-source connectivity, including robust streaming platform support via HEOS, AirPlay 2, Bluetooth 5.4, and an HDMI eARC input for TVs.
  • Innovative and fun AuraControl interface featuring a 100-LED capacitive touch volume ring and proximity sensors that auto-wake the device.
  • Convenient, highly adjustable sound profile customisation using the built-in Mirage DSP settings in the app.

What customers dislike about Marantz Grand Horizon?

  • Extremely high, luxury-tier pricing that sits out of reach for casual listeners.
  • Lacks the wide stereo separation and broad physical soundstage of a traditional dual-speaker hi-fi system setup.
  • The speaker is exceptionally heavy (upwards of 25 kg), making it difficult to move around without help.
  • The HEOS companion app interface can feel non-intuitive, dated, and lacking a premium luxury feel.
  • Occasional software-related limitations, such as a reported lip-sync lag when connected to a TV due to DSP processing overhead.
  • A few users noted that it can sound slightly dull or lack depth when playing older, less compressed classic tracks compared to modern music.
