Description

The Monitor Audio Radius 45 is an ultra-compact cube speaker measuring just 100 × 100 × 100 mm, yet it delivers impressive sound quality far beyond what its size suggests. Equipped with a 3″ MMP II bass/mid driver and a rear-firing ¾” C-CAM Gold Dome tweeter, the Radius 45 offers wide sound dispersion, clear midrange performance, and detailed high frequencies. Its small footprint makes it perfect for discreet audio setups, and it can be wall-mounted using a single-point ¼” x 20 TPI fixing or paired with optional floor stands for a clean, wire-concealed look.

Despite its compact form, the Radius 45 features advanced engineering such as a single through-bolt driver fixing that enhances cabinet rigidity and reduces unwanted resonance. The sealed cabinet design ensures tighter bass control and more accurate acoustic performance. Ideal for use as surround speakers in small home theater systems or as stereo speakers when combined with a Radius 380 subwoofer, the Radius 45 delivers high-fidelity sound in a truly space-saving design.


Features at a Glance:

  • Compact 3″ MMP II mid‑bass driver for clear mid-range and tight low frequencies

  • Sealed cabinet design for controlled, distortion-free acoustics

  • Single through‑bolt driver fixing for enhanced cabinet rigidity and clarity

  • Single‑point ¼″ × 20 TPI wall fixing bolt for invisible wall mounting

  • Optional internal stand mount with concealed wiring for a clean look

  • Rear-ported configuration for balanced sound in small spaces
