Monitor Audio Silver RXFX Surround Speaker Review

The Monitor Audio Silver RXFX (also styled RX-FX) is a dedicated surround/effects speaker from the Silver RX series, introduced around 2009–2010 as a successor to the earlier Silver RS models. Designed specifically for home theater use, it prioritizes discreet wall mounting and flexible dispersion while matching the sonic character of the rest of the Silver RX range. It was typically sold in pairs and formed part of highly regarded 5.1 systems alongside models such as the RX6/RX8 floorstanders, RX Centre, and RXW-12 subwoofer.

Design and Build

The RXFX is a compact, sealed (closed-box) two-way design optimized for wall placement. It measures approximately 300 × 120 × 250 mm (roughly 11.8″ high × 4.75″ wide × 9.8″ deep) and weighs about 4.7 kg (10.4 lbs) each. The slim profile allows it to sit close to the wall with minimal intrusion into the room.

Driver complement:

• One 6-inch (152 mm) RST C-CAM mid/bass driver (front-firing)
• Two 1-inch (25 mm) C-CAM gold-dome tweeters (side-firing, one on each side)

The cabinet uses Monitor Audio’s bolt-through driver mounting for improved rigidity and reduced vibration. A rear switch selects between bipole and dipole operation, allowing users to choose more direct or more diffuse surround effects depending on room layout and preference. Recessed terminals and wall-mounting hardware are included for clean installation. Finishes matched the rest of the Silver RX series (various real-wood veneers and high-gloss options).

Key Specifications

• Type: 2-way sealed surround speaker (bipole/dipole switchable)
• Frequency response: 60 Hz – 35 kHz
• Sensitivity: 89 dB (1 W/1 m)
• Nominal impedance: 6 ohms
• Power handling: 80 W RMS
• Recommended amplifier power: 10–80 W (some sources list 25–100 W)
• Crossover frequency: Approximately 2.1–2.5 kHz
• Dimensions: ~300 × 120 × 250 mm
• Weight: ~4.7 kg each

Sound Quality

In system reviews, the RXFX is consistently praised for its excellent timbre matching with the main Silver RX speakers and its ability to create an enveloping, immersive surround field.

• Dispersion and immersion: The dual side-firing tweeters and bipole/dipole switch deliver a convincing sense of space. In dipole mode the sound is more diffuse and atmospheric; in bipole mode it is more directional. Reviewers noted effective recreation of moving effects (such as swords whooshing or vehicles passing) with good consistency as sounds transitioned from front to rear.
• Tonal balance: Smooth and coherent with the rest of the range. The C-CAM gold-dome tweeters provide clear, detailed highs that extend well, while the RST mid/bass driver offers clean midrange and adequate upper-bass support for a compact sealed design.
• Dynamics and detail: Capable of conveying the energy and detail of movie soundtracks without strain when properly driven. The sealed cabinet contributes to tight, controlled performance even when mounted close to walls.
• Limitations: Bass extension is limited (rolling off around 60 Hz), which is expected for a small sealed surround. It relies on a subwoofer for deep low-frequency effects. Output capability is moderate, so very large rooms or extreme volume levels may benefit from additional surrounds or more powerful models.

Overall, the RXFX prioritizes seamless integration and spatial realism over raw bass or high SPLs, making it an effective partner in a matched Silver RX home theater system.

Pros

• Excellent timbre matching with Silver RX main speakers
• Flexible bipole/dipole operation
• Discreet, wall-hugging design with included mounting hardware
• Clear, detailed highs and coherent midrange
• Solid build quality and attractive finishes
• Effective immersion for movies and multichannel music

Cons

• Limited bass extension (requires a subwoofer for full-range effects)
• Moderate maximum output — not ideal for very large rooms at high volumes
• Sealed design and compact size constrain low-end authority
• Older model (succeeded by later Silver FX designs)

Verdict

The Monitor Audio Silver RXFX is a well-executed dedicated surround speaker that delivers convincing immersion and excellent system matching within the Silver RX range. Its slim wall-mountable form, switchable dispersion modes, and coherent sonic character make it a strong choice for home theater setups where discreet placement and seamless effects are priorities.

While its bass output is naturally limited by size and the sealed enclosure, it performs its intended role effectively when paired with a capable subwoofer and matching front speakers. On the used market it remains a worthwhile option for those building or completing a Silver RX-based system. Recommended for listeners seeking refined, atmospheric surrounds rather than high-output direct-radiating alternatives.
