The Monitor Audio WT380-IDC is part of their flagship 300 series of custom installation speakers, providing the best in-wall loudspeaker option for music and home theatre applications. The drivers are timbre-matched with the Monitor Audio Gold series, making them ideal to combine with the cabinet speaker range in a surround sound set-up.
At the heart of the Monitor Audio WT380-IDC is a unique Inverted Dual Concentric pivoting mid-range/tweeter module providing up to 18 degrees of play. The WT380-IDC can be discreetly positioned, and then the sound can be directed into the desired listening zone by pivoting the IDC driver module to maximize performance. The WT380-IDC is a true 3-way main speaker featuring a pivoting IDC 4-inch mid-range/1-inch tweeter module, and an 8 inch C-CAM bass driver with RST, providing higher power handling and output, and deeper bass response than the C280-IDC.
The gold dome tweeter is formed from a ceramic-coated aluminium/magnesium alloy, gold anodised to a specific thickness for ideal stiffness and damping characteristics. Its new profile and surround geometry have been developed using advanced modelling tools, to provide the optimum qualities for accurate sound reproduction. The new design moves the first order of breakup to beyond 35kHz, producing a linear response way beyond audibility, which matches the wide frequency bandwidth available from HD music and cinema sound formats. The gold dome is thinner, lighter, more rigid and therefore more efficient than domes made from other materials which are prone to distortion in the audio band.
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.
The in-ceiling and in-wall LCR models employ a unique pivoting Inverted Dual Concentric midrange/tweeter module offering up to 18 degrees of play. This allows for the speakers to be discreetly positioned and the sound to be directed toward the listening zone by pivoting the IDC driver module to maximize performance. With the IDC module installed, these architectural speakers become true 3-way designs, offering superior performance and flexibility over typical 2-way or fixed angle speakers. Within the proprietary IDC module an inverted 4" midrange driver provides superior dispersion while enabling the midrange cone and tweeter dome assembly to be set as far forward as possible, allowing a clear acoustic 'sighting' of the desired listening zone and reducing undesirable diffraction effects. It's impossible to avoid diffraction effects from conventional two-way designs, which locate the bass driver 75mm (3") to 150mm (6") behind the speaker grille.
