# Monitor Audio Radius On-Wall 4G Speaker (Each)

The Monitor Audio Radius On-Wall 4G is a slim on-wall speaker designed to integrate seamlessly around a TV screen.

It transforms TV and film sound with immersive, lifelike performance that adds real clarity, scale and impact to every scene.

Inside, the same C-CAM RST III driver and C-CAM Gold Dome tweeter technology found across the Radius 4G Series delivers precise high-frequency detail, controlled dispersion and coherent sound staging.

Its slim, low-profile form and clean contemporary aesthetic support both horizontal and vertical placement, with a removable MA roundel logo ensuring a clean, uninterrupted finish in either orientation.

-   **Dual Bass-Mid Driver Layout:** Two 4.5-inch RST III bass-mid drivers flank a 25 mm C-CAM Gold Dome tweeter for wide, immersive TV and film sound.
-   **New Crossover Design:** Precision-engineered for the 4G generation to improve integration across the driver array.
-   **Through-Bolt Driver Bracing:** Reinforces the driver mounting for a more rigid, resonance-free cabinet.
-   **HiVe II Ports:** Reduce turbulence and port noise for cleaner, more controlled bass.
-   **Flexible Orientation:** Horizontal or vertical placement is supported, with a removable roundel logo for a clean finish either way.
-   **Simple Installation:** Supplied with a wall bracket and fixing template for straightforward fitting.
-   **Subwoofer Ready:** Add a Monitor Audio subwoofer to unlock genuinely full-range, cinematic performance.
