These in-ceiling speakers feature a pivoting C-CAM® tweeter and a powerful 8” C-CAM bass driver featuring the Rigid Surface Technology cone surface used in Monitor Audios range-topping home audio speaker systems. A remarkable in ceiling speaker renowned for its clarity of treble.

  • Advanced in-ceiling speakers
  • Integrated fully-sealed back box
  • 8” C-CAM® RST® bass driver, 1” C-CAM pivoting tweeter
  • Tri-Grip® fixing system
  • Trim-less, low profile, paintable grille

Alongside a pivoting C-CAM® tweeter, the CP-CT380 model introduces a powerful 8” C-CAM bass driver featuring the Rigid Surface Technology (RST®) cone surface employed by our range-topping home audio speaker systems.

The flagship ‘Trimless’ 300 Series three-way loudspeakers provide the finest Monitor Audio in-wall and in-ceiling loudspeaker options for music and home theatre applications. They marry C-CAM® bass drivers with RST® cone profiles, and a cast-aluminum driver chassis with an IDC® driver module to provide deeper bass, higher system output, and greater power handling than the ‘Trimless’ 200 Series three-way models. Optimum imaging and set-up are established via the pivoting IDC, high-frequency (+3dB / 0dB / -3dB) level adjustment, and Boundary Compensation (on /off) controls.


Refined over many years by Monitor Audio, Ceramic-Coated Aluminium/Magnesium is used as a driver cone material for all our speaker designs from the mid-market models up. Originally developed by the aerospace industry for jet engine components, C-CAM's properties are ideal for loudspeaker cones being extremely rigid, yet light enough to yield high overall efficiency. C-CAM bass drivers are able to resist the bending distortion imposed by sudden and extreme bass excursions to reproduce very clean, deep and dynamic bass frequencies. Conventional cone materials are more likely to flex in operation, producing a significant level of audible distortion.


The Rigid Surface Technology (RST) cone profile is inspired by the Japanese art of Origami, which demonstrates how a very light material (like paper) can be strengthened and made more rigid by making small and precise folds on its surface. Monitor Audio has applied this principle in designing the CAM/RST cones for the GX and RX ranges. Developed and perfected using sophisticated computer modelling (Finite Element Analysis), the GX mid and bass driver cones have been strengthened by a series of radial ribs; the RX driver cones by a pattern of dimples. Our simulations have proved that RST significantly increases cone rigidity, allowing the radiating surfaces to resist mechanical bending forces, which can twist the shape of conventional driver cones to produce distorted sound. The strengthening effect of RST means that we can use thinner, lighter and more responsive C-CAM cones, which provide speed and accuracy while offering greatly reduced distortion. The RST patterns also help to displace standing waves that can propagate on the cone's surface.
