Monitor Audio Radius 45 Ultra-Compact Satellite Speakers

Monitor Audio Radius 45 satellite speaker

The Monitor Audio Radius 45 satellite speaker is engineered to deliver high-quality audio performance from an ultra-compact enclosure suitable for discreet stereo, surround sound, and multi-room installations. Designed for flexible placement around the home, the Radius 45 combines advanced driver technology, wide sound dispersion, and precision cabinet engineering to produce clear, balanced sound from a remarkably small footprint.

Configured as a two-way sealed speaker system, the Radius 45 features a rear-firing ¾-inch C-CAM Gold Dome tweeter and a front-firing 3-inch MMP II bass/mid driver. The rear-firing tweeter design improves sound dispersion characteristics, creating a wider and more immersive soundstage while maintaining detailed and accurate high-frequency reproduction. The gold dome tweeter utilizes ceramic-coated aluminum magnesium construction for low distortion, improved rigidity, and extended high-frequency performance.

The 3-inch MMP II bass/mid driver incorporates Metal Matrix Polymer cone technology, combining lightweight construction with excellent rigidity for responsive midrange clarity and controlled bass output. Advanced cone geometry and high-pressure injection molding improve consistency and sonic precision across the frequency range.

Its sealed acoustic suspension cabinet design enhances transient accuracy while minimizing unwanted resonance, making the Radius 45 suitable for compact listening spaces and wall-mounted applications. A single through-bolt driver mounting system increases cabinet rigidity and reduces vibration for improved midrange detail and overall clarity.

The compact cabinet is finished with rounded edges, metal mesh grille detailing, and premium lacquer finishes for seamless integration into modern interiors. Flexible placement options include shelf positioning, stand mounting, or optional wall-mount installation using the integrated threaded fixing point.
