With eight individually powered drivers, Marantz Rise amplification technology, and proprietary Mirage DSP, Grand Horizon is designed to deliver the scale, dynamics, and detail of a sophisticated hi-fi system from a single enclosure.\u003c\/p\u003e\u003cp\u003eAs the flagship of the Marantz Horizon wireless speaker family, Grand Horizon brings together the company's audio engineering heritage and a striking contemporary design. Its sculptural form, seamless 360° fabric covering, and intuitive AuraControl interface make it as much a carefully considered piece of furniture as a serious audio component. With HEOS Built-in, Apple AirPlay 2, Bluetooth, Spotify Connect, HDMI eARC, and extensive wired connectivity, Grand Horizon can serve as a complete music and entertainment system without requiring separate amplification or loudspeakers.\u003c\/p\u003e\u003ch4\u003eMarantz Rise Amplification\u003c\/h4\u003e\u003cp\u003eAt the heart of Grand Horizon is Marantz Rise, a proprietary amplifier design employing gallium nitride field-effect transistors (GaN FETs). These devices can switch rapidly and efficiently, allowing the amplifier to deliver substantial power from a compact architecture while maintaining precise control of the loudspeaker drivers.\u003c\/p\u003e\u003cp\u003eGrand Horizon delivers 370 W of total amplifier power under the FTC rating standard, with an advertised peak output of 860 W. Marantz also specifies 1,400 W of peak raw amplifier power, a figure describing the amplifier's potential peak capability rather than continuous acoustic output. The two peak figures are not measured under the FTC standard.\u003c\/p\u003e\u003cp\u003eThis powerful amplification system provides the headroom needed for demanding musical passages, helping Grand Horizon reproduce dynamic contrasts and deep bass without the limitations commonly associated with smaller wireless speakers.\u003c\/p\u003e\u003cp\u003eMarantz's Sound Master tuning process further refines the speaker's performance through careful listening evaluations and adjustments to its amplification, driver integration, and digital processing. The result is intended to deliver the company's characteristic balance of musical detail, tonal richness, and spaciousness.\u003c\/p\u003e\u003ch4\u003eEight-Driver Acoustic Architecture\u003c\/h4\u003e\u003cp\u003eGrand Horizon incorporates an eight-driver array engineered to reproduce a wide frequency range with substantial output and controlled dispersion. At its foundation is a single 8\" Marantz Gravity bass driver, supported by four 3\" wideband drivers and three 1\" high-frequency drivers.\u003c\/p\u003e\u003cp\u003eThe Marantz Gravity drivers use powerful neodymium magnets to provide the magnetic force required for precise cone control. Their design is intended to combine strong dynamic performance with low distortion, even at elevated playback levels.\u003c\/p\u003e\u003cp\u003eThe 8\" bass driver provides the low-frequency foundation, while the four wideband drivers handle much of the musical information through the midrange. Three high-frequency drivers reproduce upper-frequency detail and contribute to the speaker's broad sound dispersion.\u003c\/p\u003e\u003cp\u003eThis arrangement allows Grand Horizon to achieve a specified frequency response of 28 Hz to 20 kHz (±3 dB), extending to 18 Hz at -10 dB. Maximum sound pressure level is rated at 111 dB at 1 m, with peak output reaching 122 dB at the same distance.\u003c\/p\u003e\u003cp\u003eThe combination of dedicated drivers, substantial amplification, and carefully optimized processing allows Grand Horizon to deliver full-range sound from a single enclosure without relying on an external subwoofer.\u003c\/p\u003e\u003ch4\u003eMarantz Mirage Digital Signal Processing\u003c\/h4\u003e\u003cp\u003eMarantz Mirage is a proprietary digital signal processing system developed specifically for the Horizon speaker family. Rather than treating the multiple drivers as a conventional pair of stereo loudspeakers, Mirage DSP coordinates their output to produce a cohesive soundstage extending beyond the physical boundaries of the enclosure.\u003c\/p\u003e\u003cp\u003eDigital processing manages the interaction between the bass, wideband, and high-frequency drivers, optimizing their contributions across the audible frequency range. This allows Grand Horizon to create a convincing sense of musical space while maintaining tonal balance and clarity.\u003c\/p\u003e\u003cp\u003eThe processing system also helps Grand Horizon maintain consistent performance across different listening levels and musical material, allowing the speaker to handle everything from intimate acoustic recordings to large-scale orchestral and electronic music.\u003c\/p\u003e\u003cp\u003eWith support for Dolby Atmos and other multichannel audio formats, Grand Horizon can also process immersive soundtracks and distribute their information across its eight-driver array. Although it remains a single-enclosure speaker rather than a discrete multichannel system, Mirage DSP is designed to create a more expansive presentation than its physical dimensions might suggest.\u003c\/p\u003e\u003ch4\u003eHigh-Resolution Music Streaming With HEOS\u003c\/h4\u003e\u003cp\u003eWith HEOS Built-in, Grand Horizon provides convenient access to music streaming services, internet radio, and locally stored digital music. The HEOS app allows listeners to browse music, select sources, adjust volume, and control playback from a smartphone or tablet.\u003c\/p\u003e\u003cp\u003eSupported streaming services include Amazon Music, TIDAL, Spotify, Pandora, Deezer, SiriusXM, iHeartRadio, TuneIn, SoundCloud, and others, with availability varying by region. HEOS also provides access to music stored on compatible network-attached storage devices and computers connected to the same network.\u003c\/p\u003e\u003cp\u003eFor listeners with their own digital music libraries, Grand Horizon supports high-resolution PCM playback up to 24-bit\/192 kHz and DSD files at 2.8 MHz and 5.6 MHz. Supported formats include FLAC, ALAC, WAV, MP3, AAC, WMA, and DSD.\u003c\/p\u003e\u003cp\u003eApple AirPlay 2 makes it easy to stream directly from an iPhone, iPad, or Mac, while Bluetooth 5.4 provides a convenient wireless connection for compatible devices. Spotify Connect offers direct control of Spotify playback from the Spotify app.\u003c\/p\u003e\u003cp\u003eUSB-C storage playback provides another way to enjoy locally stored music without requiring a computer or network connection. Compatible FAT32- and NTFS-formatted storage devices can be connected directly to the speaker.\u003c\/p\u003e\u003ch4\u003eMultiroom Audio Made Simple\u003c\/h4\u003e\u003cp\u003eGrand Horizon can also be part of a larger HEOS multiroom audio system. Connect additional HEOS-enabled Marantz or Denon components throughout the home, and use the HEOS app to play different music in different rooms or synchronize playback across multiple listening areas.\u003c\/p\u003e\u003cp\u003eThis allows Grand Horizon to serve as the primary music system in a living room or other large space while smaller HEOS speakers provide music in bedrooms, offices, kitchens, or secondary listening areas.\u003c\/p\u003e\u003cp\u003eEach zone can be controlled independently, with separate source selection and volume adjustment. Alternatively, multiple HEOS devices can be grouped together for synchronized music playback throughout the home.\u003c\/p\u003e\u003ch4\u003eBetter TV Sound With HDMI eARC\u003c\/h4\u003e\u003cp\u003eGrand Horizon is equally capable as the centerpiece of a television audio system. Its HDMI eARC connection allows audio from a compatible television to be reproduced through the speaker, providing an alternative to a conventional soundbar or separate AV receiver and loudspeaker system.\u003c\/p\u003e\u003cp\u003eBuilt-in decoding supports Dolby Atmos, Dolby TrueHD, Dolby Digital Plus, Dolby Digital, and multichannel LPCM, allowing Grand Horizon to handle audio from television broadcasts, movies, games, and streaming video services.\u003c\/p\u003e\u003cp\u003eThe HDMI connection supports enhanced Audio Return Channel (eARC) and conventional ARC operation, allowing compatible televisions to send audio to the speaker through a single HDMI cable.\u003c\/p\u003e\u003cp\u003eFor multichannel sources, Grand Horizon supports PCM signals up to 24-bit\/192 kHz across as many as 7.1 channels. Marantz Mirage processing then adapts the incoming material for reproduction through the speaker's integrated driver array.\u003c\/p\u003e\u003cp\u003eAn optical digital input provides an additional connection for compatible televisions, CD players, and other digital audio components.\u003c\/p\u003e\u003ch4\u003eMarantz AuraControl Interface\u003c\/h4\u003e\u003cp\u003eGrand Horizon features Marantz AuraControl, an integrated user interface designed to make everyday operation intuitive without compromising the speaker's appearance. Touch-sensitive controls provide convenient access to volume adjustment and playback functions, with multicolored LED illumination communicating operating status.\u003c\/p\u003e\u003cp\u003eThe controls are integrated into the speaker's distinctive design, avoiding the visual clutter of a conventional control panel. Volume adjustment, play\/pause operation, and source control can also be managed through the HEOS app.\u003c\/p\u003e\u003cp\u003eDedicated connection and Bluetooth buttons on the rear panel simplify initial setup and wireless pairing.\u003c\/p\u003e\u003cp\u003eThis combination of onboard controls and app-based operation makes Grand Horizon suitable for both casual listening and more elaborate network audio systems.\u003c\/p\u003e\u003ch4\u003eMarantz Radiance 360° Seamless Fabric\u003c\/h4\u003e\u003cp\u003eThe exterior of Grand Horizon features Marantz Radiance, a specially developed 360° seamless fabric covering. Designed to balance visual appearance, tactile quality, durability, and acoustic transparency, the material wraps around the speaker's sculptural enclosure without the conventional grille seams found on many loudspeakers.\u003c\/p\u003e\u003cp\u003eThe fabric is engineered to allow sound from the internal drivers to pass through with minimal obstruction while maintaining a consistent appearance from different viewing angles.\u003c\/p\u003e\u003cp\u003eMarantz has also incorporated design elements inspired by its traditional hi-fi components, translating the company's recognizable visual identity into a new form intended for prominent placement within a living space.\u003c\/p\u003e\u003cp\u003eGrand Horizon is available in three finishes: Midnight Sky, Moon Ray, and Marantz Champagne. Each finish presents a different interpretation of the speaker's combination of textured fabric, refined detailing, and sculptural form.\u003c\/p\u003e\u003ch4\u003eFlexible Connectivity and System Integration\u003c\/h4\u003e\u003cp\u003eAlong with its extensive wireless capabilities, Grand Horizon provides a stereo RCA analog input for connecting conventional audio sources, an optical digital input, HDMI eARC\/ARC, and a USB-C port for compatible storage devices.\u003c\/p\u003e\u003cp\u003eWired Ethernet and dual-band Wi-Fi provide flexible network connectivity.
