Audio T Verdict
The Bronze AMS 7G provides a particularly neat way of adding Dolby Atmos height channels to a Monitor Audio Bronze 7G home cinema system. It is compact, purpose-built and designed to sit directly on top of either the Bronze 50 7G or Bronze 300 7G.
Importantly, this is more than simply a small speaker in an angled cabinet. Monitor Audio uses a dedicated two-way design with a 4-inch C-CAM driver, 25mm C-CAM Gold Dome tweeter, sealed enclosure and its own newly developed crossover.
If you are already building a Bronze 7G surround system and want to add Dolby Atmos without cutting speakers into the ceiling, the Bronze AMS 7G is the obvious place to start.
Monitor Audio Bronze AMS 7G
The Bronze AMS 7G is the dedicated Dolby Atmos-enabled speaker in Monitor Audio's seventh-generation Bronze Series.
Its compact two-way design combines a 4-inch C-CAM driver with the latest 25mm C-CAM Gold Dome tweeter and UD waveguide, all housed within a sealed cabinet designed specifically for height-channel duties.

Dolby Atmos Height Effects
Dolby Atmos adds a vertical dimension to a conventional surround-sound system, allowing compatible soundtracks to place effects above the listening position as well as around it.
The Bronze AMS 7G is designed as an upward-firing Dolby Atmos module. Rather than mounting a loudspeaker directly into the ceiling, the AMS directs its output upwards so that the reflected sound contributes to the impression of sound arriving from overhead.
This can make effects such as weather, aircraft, ambience and movement through a film soundtrack feel more convincing while expanding the overall sense of space within a home cinema system.
Dolby Atmos Setup
The Bronze AMS 7G requires a compatible Dolby Atmos AV amplifier or receiver with sufficient amplified channels for your chosen speaker configuration. Room calibration should then be carried out with the AMS speakers assigned as Dolby Atmos-enabled height channels.
Designed for Bronze 50 and Bronze 300
Monitor Audio has designed the Bronze AMS 7G specifically to sit on top of either the Bronze 50 7G bookshelf speaker or the Bronze 300 7G floorstanding speaker.
The 185mm width of the AMS cabinet also complements the proportions of the main Bronze loudspeaker cabinets, helping the Atmos module look like an integrated part of the system rather than an unrelated speaker placed on top.
Matching Walnut, Black and White finishes are available across the range, allowing a complete Bronze 7G home cinema system to maintain a consistent appearance.
Latest C-CAM Gold Dome Tweeter
High frequencies are reproduced by Monitor Audio's latest 25mm C-CAM Gold Dome tweeter.
The tweeter is partnered with an optimised waveguide that helps control dispersion and integrate its output with the larger C-CAM driver.
For an Atmos speaker, controlled dispersion is particularly important because the output needs to be directed appropriately into the room rather than behaving like a conventional forward-firing loudspeaker.
4-Inch C-CAM Driver
A dedicated 4-inch C-CAM driver handles the lower part of the Bronze AMS 7G's operating range.
C-CAM stands for Ceramic-Coated Aluminium Magnesium and is Monitor Audio's long-established rigid, lightweight diaphragm technology.
In the Bronze AMS 7G, the compact driver allows Monitor Audio to keep the enclosure relatively small while still providing the output and control required for convincing surround and height effects.
83Hz to 30kHz In-Room Response
Monitor Audio specifies an in-room -6dB frequency response of 83Hz to 30kHz.
The Bronze AMS 7G is not intended to reproduce the deepest bass within a cinema system. Low-frequency information is normally handled by the main speakers and subwoofer, allowing the AMS to concentrate on the height information for which it has been designed.
Sealed Cabinet Design
Unlike the ported Bronze 50 and Bronze 300, the Bronze AMS 7G uses a sealed enclosure.
This removes the need for a bass-reflex port and suits the compact dimensions and specialised operating role of an upward-firing Atmos speaker.
The cabinet measures just 173mm high, 185mm wide and 302mm deep with all standard accessories fitted.
New Bronze 7G Crossover
The Bronze AMS 7G uses a newly developed crossover designed specifically around its 4-inch C-CAM driver and Gold Dome tweeter.
The crossover frequency is set at 4.8kHz, dividing the operating range between the two drive units.
This dedicated crossover allows the AMS to be engineered around its particular height-channel role rather than simply adapting the crossover network from one of the conventional Bronze loudspeakers.
86dB Sensitivity
The Bronze AMS 7G has a free-field sensitivity of 86dB at 2.83V/1m.
Nominal impedance is 8 ohms, with Monitor Audio specifying a minimum impedance of 3.7 ohms at 10kHz.
These figures make it suitable for use with a broad range of modern AV amplifiers and receivers, provided the amplifier is correctly matched and configured for the complete speaker system.
Amplifier Matching
Monitor Audio publishes separate amplifier recommendations according to the amplifier's rated load:
- Into 8 ohms: 10 to 60W RMS
- Into 4 ohms: 30 to 120W RMS
The Bronze AMS 7G itself has a continuous power-handling specification of 60W under the CTA 426-B measurement standard.
When planning a multi-channel system, amplifier choice should be considered across the complete speaker package rather than looking at the AMS modules in isolation.
110dB Maximum Peak SPL
Monitor Audio specifies a maximum peak sound pressure level of 110dB using the AES75 Z-weighted measurement method.
This gives the compact Bronze AMS useful headroom for reproducing the short, dynamic effects and spatial information encountered within modern film and television soundtracks.
Compact Dimensions
With all standard accessories fitted, each Bronze AMS 7G measures:
- Height: 173mm
- Width: 185mm
- Depth: 302mm
- Weight: 3.1kg each
The compact footprint allows the AMS to sit neatly on its matching Bronze loudspeaker without making the complete installation unnecessarily bulky.
Bronze 50 or Bronze 300 Installation
The same Bronze AMS 7G can be partnered with either of Monitor Audio's main stereo speakers in the Bronze Series 7G.
Bronze 50 7G with AMS
- Compact bookshelf speaker system
- Ideal where floor space is more limited
- AMS sits directly on top of Bronze 50
- Matching 185mm cabinet width
- Suitable for compact Bronze 7G cinema systems
Bronze 300 7G with AMS
- Full-size floorstanding speaker system
- Greater bass extension from the main speakers
- AMS sits directly on top of Bronze 300
- Integrated visual appearance
- Suitable for larger Bronze 7G cinema systems
Three Finishes
The Bronze AMS 7G is available in three current finishes:
The finishes coordinate with the rest of the Bronze Series 7G, making it easier to build a visually consistent multi-channel speaker package.
Supplied as a Pair
The Bronze AMS 7G is supplied as a pair.
One pair can therefore provide two Dolby Atmos height channels within a compatible AV system. More complex Atmos layouts may require additional height speakers and corresponding amplifier channels.
Part of the Complete Bronze 7G Range
The Bronze AMS 7G forms part of a complete family of matching Monitor Audio speakers designed for both stereo and home cinema installations.
Matching Bronze 7G models include:
- Bronze 50 7G bookshelf speakers
- Bronze 300 7G floorstanding speakers
- Bronze Centre 7G centre speaker
- Bronze On-Wall 7G speaker
This allows a complete Bronze Series home cinema system to be assembled using speakers designed to work together both visually and acoustically.
