A built-in enclosure elevates your sound 

One of my favorite features of Monitor's Controlled Performance series is the back-box that's built onto each model. This carefully designed enclosure helps the speaker deliver consistently focused, well-balanced sound no matter what kind of space is behind it in your wall. It also keeps dust and dirt out of your speaker.

The speaker's built-in back-box keeps dust and dirt out, and helps deliver consistently balanced sound.

Monitor Audio's secret sauce

The 1" dome tweeter and dual 4" woofers are made from Monitor's high-tech ceramic-coated aluminum/magnesium alloy. This exceptionally stiff, lightweight material allows the drivers to respond swiftly and precisely to the audio signal for greater accuracy.

The tweeter also gets an anodized coating of gold that ensures smooth, extended highs. It also pivots, so you can aim it toward your preferred listening spot for more direct sound.

Awesome speaker. Using three as LRC for 5.1 system using CP-CT260 for in-ceiling surround. Matched with SVS SB-2000 and powered via Marantz 5012. The only caveat would be I think they could use more power (previously driven by a Rotel @ 80/wpc), but plenty loud for my 12 x 15 room.

Product Research


LCR Design: The Monitor Audio CP-WT240-LCR is a multi-purpose in-wall speaker that can be used as a center speaker, front left or right speaker, and surround left or right speaker. Its suitable for music and home theater applications, and can be mounted in a portrait or landscape orientation.

Two-Way Speaker Design: The Monitor Audio Custom Install series CP-WT240-LCR in-ceiling speaker features a two-way driver design with a 1" C-CAM gold dome pivoting tweeter and two 4" C-CAM midrange/midbass woofers. The two 4" woofers offer greater radiating area working in tandem than a single 6" bass driver.

  • 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 Woofers: 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.

Tweeter & Boundary Control: The 1" C-CAM tweeter is able to pivot (+/-15°) to direct the sound to your desired listening area. A tweeter level adjustment (+3/0/-3 dB) and boundary compensation control (On/Off) also aids in high frequency performance and optimum imaging.

Sealed Design: The Monitor Audio CP-WT240-LCR's airtight enclosure design protects each precision-engineered driver system against the accumulation of damaging dirt and dust.

Trimless Grille: The CP-WT240-LCR in-ceiling speaker features a round "Trimless" 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 but provides three times 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.

Note: This Custom Install series loudspeaker can only be fixed into drywall with a thickness of up to 1.75".

Spring-Post Terminals: The Monitor Audio CP-WT240-LCR is fitted with two spring-post terminals to connect your speaker wire. The spring-post terminals which accept bare wire (up to 10AWG) and angled pin-connectors.
