Monitor Audio WT380-IDC
"Trimless 300" Series 3-way in-wall speaker with 8" woofer
Our take on the Monitor Audio WT380-IDC by Crutchfield's Kramer Crane
Unrivaled sound, invisible footprint
Looking for spectacular sound with zero footprint in your room? Then install a pair of Monitor Audio WT380-IDC in-wall speakers. This audiophile-quality speaker is packed with technology to get the most out of any audio source. It's the perfect choice for a high-end home theater, or a dedicated listening room.
High-tech drivers for better sound
One of Monitor Audio's hallmark technologies is their "C-CAM" driver material. It's a ceramic-coated aluminum/magnesium alloy originally developed by the aerospace industry for jet engine components. It's super-lightweight and strong, which allows the drivers to respond very quickly and precisely.
The WT380-IDC has three separate drivers, all made from this material: a 1" dome tweeter, a 4" midrange, and a beefy 8" woofer.
Aim your sound for better results
Monitor Audio mounted the tweeter and midrange driver together on a pivoting module. This lets you aim the mids and highs toward you for better clarity, detail, and spatial imaging. The tweeter is treated with an anodized layer of gold for smooth, extended high-frequency response.
Monitor Audio's rotating-cam design makes your in-wall installation go smoother. Once you have the WT380-IDC in place, simply use a screwdriver to tighten each cam for a secure grip against the back of the wall.

3-Way Speaker Design: The Monitor Audio WT380-IDC in-wall loudspeaker features an 8" C-CAM RST bass driver and a pivoting IDC module, housing a 4" C-CAM RST inverted midrange driver and a 1" C-CAM gold dome tweeter. This true 3-way design provide rich midrange detail, higher system output, greater power handling, and superior vocal intelligibility and sound localization.
IDC Module: The Monitor Audio WT380-IDC in-wall speaker employs a unique pivoting Inverted Dual Concentric (IDC) midrange/tweeter module which allows you to angle the midrange and tweeter up/down or left/right. This allows for the in-wall speaker 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, the in-wall speaker becomes a true 3-way design, 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 the clear acoustics 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 3" to 6" behind the speaker grille.
C-CAM Technology: C-CAM drivers are used throughout the WT380-IDC in-wall loudspeaker, providing coherent tonal balance and sonic signature across the entering audio frequency spectrum.
- C-CAM Gold-Dome Tweeter: The gold dome tweeter is formed from a ceramic-coated aluminum/magnesium alloy, gold anodized to a specific thickness for ideal stiffness and damping characteristics. Its new profile and surround geometry have been developed using advanced modeling 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.
- C-CAM Cone Midrange and Bass Driver: Ceramic-Coated Aluminum/Magnesium is a material originally developed by the aerospace industry for jet engine components. Its properties are ideal for loudspeaker cones being extremely rigid, yet light enough to yield high overall efficiency. In manufacture, aluminum/magnesium alloy undergoes a three-stage stress-relieving process to remove surface deformation and molecular weakness. Once formed, the alloy cone is subjected to a high temperature anodic coating process in which a layer of pure ceramic alumina is depleted onto its surfaces to a depth of 50 microns, producing a completely rigid sandwich of alloy and heat-dissipating ceramic material. Conventional cones are liable to flex or twist in operation, producing a significant level of audible distortion. C-CAM cones have a much higher resistance to bending stress and therefore exhibit much greater fidelity over their entire operating range.
RST (Rigid Surface Technology): The WT380-IDC in-wall speaker's inverted midrange driver and bass driver combine Rigid Surface Technology (RST) with C-CAM cone woofer design for a stronger, lighter weight cone. The Rigid Surface Technology (RST) cone profile was 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 it surface. Developed and perfect using sophisticated computer modeling (Finite Element Analysis), these drivers have been strengthened by a pattern of dimples. 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 Monitor Audio can use thinner, lighter and more responsive C-CM 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.
Controls: The WT380-IDC offers High Frequency, Mid Frequency, and Boundary Compensation controls on the front-baffle, hidden behind the grille.
- High Frequency Level Control: A HF (High Frequency) level adjustment also aids in high frequency performance. With the High Frequency Level Control set to "0", the in-wall speaker will give you a neutral sound. Switching to the "+3db" setting will give the high frequencies a boost, giving you more clarity and presence in the treble. If you want more prominence in the bass frequencies, switch to the "-3db" setting. The HF level adjustment switch is located on front of the baffle behind the grille.
- Mid Frequency Level Control: A MF (Mid Frequency) level adjustment also aids in midrange frequency performance. With the High Frequency Level Control set to "0", the in-wall speaker will give you a neutral sound. Switching to the "+3db" setting will give the high frequencies a boost, giving you more clarity and presence in the midrange. If you want more prominence in the high & low frequencies, switch to the "-3db" setting. The MF level adjustment switch is located on front of the baffle behind the grille.
- Boundary Compensation Control: The Boundary Compensation control reduces the speaker's bass output level to compensate for the greater reflection of bass energy when the speaker is placed near a wall. It can be set to "On" or "Off". The Boundary Compensation control is located on the front baffle and hidden behind the grille.
Spring-Post Terminals: The Monitor Audio WT380-IDC is outfitted with two gold-plated spring-post terminals to connect your speaker wire. The spring-post terminals which accept bare wire (up to 10AWG), banana plugs (sing/dual), and angled pin-connectors.
"Trimless" Magnetic Grille: The WT380-IDC in-wall speaker features a steel-mesh grille that is held in place by high strength Neodymium magnets covering the entire speaker for a true "trimless", stealth look. The grille is paintable to blend with the living environment; additional scrim material is provided for trouble free painting.
Tri-Grip Fixing System: Monitor Audio's innovative Tri-Grip fixing system is easier to install than conventional clamping schemes and provides 3x the surface area and a better surface seal, maximizing bass response and midrange clarity. The Tri-Grip fixings are made from a tough re-enforced polymer, giving a secure installation.
