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. RST uses a pattern of surface dimples to stiffen the cone for higher output and reduced distortion. A wider overall response and greater power-handling are attenuated according to taste by in-room high frequency and boundary compensation controls.
C-CAM Bass Drivers
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.
