Marantz Cinema 70s Receiver & Wharfedale Diamond 12.1i 5.1 Package, Black Overview
The Marantz Cinema 70s Receiver & Wharfedale Diamond 12.1i 5.1 Package is designed for home cinema fans who want immersive surround sound without filling the room with bulky equipment.

Modern HDMI support makes it well-suited to current TVs, consoles, and fast-paced content, while automatic room calibration helps the system adapt to your space with minimal setup.

Full Description
View Full DescriptionSlim Design With Room To Grow
The Cinema 70s keeps a low profile at under 20cm tall, making it easy to fit into TV units or hi-fi racks without dominating your space. This slim design helps your setup look neat and intentional, especially in living rooms where space matters. Despite its compact size, you still get seven powered channels and support for speaker layouts from 2.1 up to 7.2. You can start with a simple system today and expand later, without needing to replace your receiver.
Immersive Surround Without Complexity
Support for Dolby Atmos and DTS:X helps create a surround sound experience that feels wider and more involving, even without dedicated height speakers. Sound effects are placed more clearly around the room, while dialogue and subtle details stay easy to follow. Audyssey MultEQ room correction simplifies setup by measuring your room and automatically adjusting speaker levels and distances. This reduces guesswork and manual tweaking, helping you achieve balanced sound more quickly so you can focus on enjoying films rather than fine tuning settings.
Built For Modern Entertainment
Multiple HDMI inputs support 8K and 4K at 120Hz, making the Cinema 70s a strong match for modern TVs, games consoles, and fast moving content. Low latency passthrough and variable refresh rate support help keep gameplay smooth and responsive. Built-in streaming allows wireless music playback through services like Spotify Connect and HEOS, reducing the need for extra boxes. A dedicated phono input also lets you connect a turntable, making it easy to switch between films, games, and vinyl listening.
Balanced Bookshelf Performance
The Diamond 12.1i bookshelf speakers form the core of the system, covering front and surround roles with consistent clarity. Their midrange focused tuning keeps effects, music, and ambience sounding natural, which reduces fatigue during longer sessions. Compact cabinets make placement simple on shelves or stands, even in tighter rooms. Bass output is deliberately controlled, helping the speakers blend smoothly with a subwoofer rather than overpowering it. This balance makes them well suited to mixed use, from film nights and gaming to everyday music listening without added complexity.
Clear And Focused Dialogue
The Diamond 12C centre speaker is designed to keep dialogue clear and intelligible, even when scenes become busy or action heavy. Its horizontal cabinet fits neatly below a television, making system layout easier and more flexible. Tuning focuses on vocal presence, so speech stays anchored to the screen rather than drifting into the room. This helps conversations sound natural and easy to follow, which is especially valuable for films and series where music and effects can otherwise mask voices during everyday viewing at realistic volume levels at home.
Controlled Low Frequency Impact
The Wharfedale SW-10 subwoofer brings weight and scale to the system by handling low frequencies beyond the reach of compact speakers. Its active design delivers impact for explosions, soundtracks, and atmospheric effects, helping scenes feel more physical. Bass remains controlled rather than boomy, so it supports the rest of the speakers without drawing attention to itself. Adjustable controls let you fine tune output to suit your room, ensuring added depth and presence without overwhelming the overall balance at sensible listening levels for films and music alike use.
