Our take on the Monitor Audio CWT180

Sure, we've got custom-install speakers from Monitor Audio that are packed with even more high-end technologies than the CWT180, but this slim, stealthy model delivers what we think many people will find to be a really useful combination of installation convenience and performance features.

The "sweet spot" of performance and convenience

Sure, we've got custom-install speakers from Monitor Audio that are packed with even more high-end technologies than the CWT180, but this slim, stealthy model delivers what we think many people will find to be a really useful combination of installation convenience and performance features.

Discreet, easy-to-install design

Monitor Audio CWT180

Choose the CWT180 with a round or square grille to match your application and preference.

All the models in Monitor's CWT (Ceiling/Wall Trimless) Series measure less than 4" deep and come with your choice of round or square paintable grilles. Add to that a splash- and humidity-proof design, and that means you can use these speakers in just about any application around your home. Monitor's Tri-Grip® mounts make it easier to fasten the speaker in your ceiling or wall and ensure a tight seal.

Great sound for your custom-installed system

The CWT180 offers impressive performance thanks to Monitor's ingenious driver designs. Take, for example, the advanced gold dome tweeter. It's the same one that Monitor uses in many of its traditional cabinet-style speakers, crafted from a high-tech aluminum/magnesium alloy and treated with an anodized layer of gold for even smoother sound. The tweeter pivots, so you can aim the highs toward your favorite listening spot. You also get a sizeable 8" polymer woofer for clear mids and punchy bass.

Love that sound.

Pros: All the above

Cons: None,

Crutchfield Customer Review (What's this?)

Installed outside under lanaii. They do sound very good for playing music outside. Booming bass was not expected, but the sound is full and clear. These were chosen for the humidity and weather feature. They appear to be solidly made but time will tell how they hold up with the lake weather. Magnetic grills work perfectly and look great. Install is straight forward - holding speaker over head while pinching wire clamp to insert speaker wire is the trickiest part. Don't see a star rating - I'd give between 4.5 and 5. I do recommend.

Pros: Very nice sound. Weather feature. Great sealing grills.

Cons: Seems a wire attachment to connect to beam in attic would be a benefit at least as a safety precaution. These are not light-weight speakers.

Product Research


Two-Way Speaker Design: The Monitor Audio Custom Install series CWT 180 (Round) in-ceiling speaker features a two-way driver design with a 1" C-CAM gold dome pivoting tweeter and a 8" MMP II midrange/midbass woofer.

  • 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.
  • MMP II Midrange/Midbass Woofer: The Metal Matrix Polymer (MMP II) driver cone has a polypropylene base loaded with metallic particles to offer a rigid and responsive structure. They are manufactured using a sophisticated high-pressure injection process, which modulates cone thickness at critical points to optimise stiffness and consistency, resulting in a superior sonic performance.

Trimless Grille: The CWT 180 (Round) 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 CWT 180 (Round) 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.

Protective Covers: The CWT 180 (Round) features dust protection covers that are designed to prevent the ingress of dirt or dust into the driver and crossover.

Moisture & Fire Resistant: The Custom Install series in-ceiling speaker is splash and humidity proof for installation in shower rooms or pool areas. It also uses fire retardant materials specified to UL-94 VO rating.

Q & A

Customer Q&A

Crutchfield asked  
Why did you buy this?

I ordered these based on comparison shopping with similar sized speakers for their sensitivity, freq response, the 13x22 room I'm going to put them in and a conversation with a Crutchfield Advisor, which was very informative and helpful.[ David  Dec 17, 2016 ]
I prefer coaxial speakers.[ Chris  Mar 12, 2017 ]
