Monitor Audio's secret sauce 

The Radius 225's dual 4" woofer cones and 1" dome tweeter 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. And the drivers are configured to provide optimal performance whether you mount the speaker vertically or horizontally with the included bracket. 

Instead of using conventional screws, Monitor mounts each driver firmly into the cabinet using a single bolt that threads into its backplate, then attaches to the back of the enclosure. This mechanically decouples the driver and front baffle to enhance clarity and resolution, while acting as rigid cross bracing for a more solid, non-resonant cabinet.

Gorgeous build quality and design

Monitor Audio speakers have long been known for their sturdy, vault-like cabinet construction. The 225's enclosure feels solid and substantial, with an exterior that's beautifully finished in your choice of real walnut wood veneer, high-gloss black, or high-gloss white.

Monitor Audio Radius 225

Guest from Surrey, BC on 12/4/2018

I have two houses with a few 5.1 system of various pedigrees in each. I just installed a new 5.1 system with all Monitor Audio speakers except the REL 9i sub. The Radius 225 is paired with the silver 300 as fronts and two in ceiling CW180 for the rears. The 225 is an amazing compliment to this system. I was worried as it was smaller in stature and cheaper than the bigger units but thus turned out sounding just great.

Pros:

Cons:

Fabulous as a center channel.

Tom from Kansas City, MO on 10/6/2018

Crutchfield Customer Review (What's this?)

I am using this as a center, hanging under my TV on a MantelMount. I chose it for its size and based on my past experience with Monitor Audio. I couldn't be happier. This speaker presents dialog much more clearly than others I have tried, revealing the true nature of each actor's voice. I paired this with Monitor Bronze 1 for the left/right channels, and they blend well. If there is one thing I would change it is the wall mounting system. The attachment to the speaker is 2 simple keyholes. These are functional and would be fine on a fixed wall. However on a moving mount I would appreciate if it were something more secure. It has not been a problem yet but I fear the day that someone grabs or bumps the speaker while moving the TV, as it would not be difficult to lift and knock off of the keyhole.

Pros: Fabulous vocal and dialog representation.

Cons: Wall mount could be more secure.

Amazingly loud, crisp, clean sound

Crutchfield Customer Review (What's this?)

These are my favorite speakers. They sound incredible and are very stylish which is hard to find. The nicer setups are usually very big and bulky and you want to hidden them as much as possible. These you will not. Perfect mix between high end sound and overall clean appearance.

Pros: Very Loud Smaller in size (shallow) Clean crisp sound Bright white color Stylish design - makes you want to showcase it versus make it hidden Versitile speaker can be center channel or fronts Pairs very well with rest of Monitors line (sub, book shelf speakers)

Cons: $$, but was worth it. Couldn't find anything else in white that I could match my whole home theatre system with.

Amazing sound out of such a small speaker!

Mike from Syracuse, NY on 6/4/2018

Crutchfield Customer Review (What's this?)

Amazing sound out of such a small speaker! I was very limited with the amount of space I had available and was concerned I would not be able to find a Center Channel with full rich sound. I'm happy to say Monitor Audio delivered with a speaker that not only sounds incredible, but also has the added bonus of looking fantastic.

Pros: Sound Looks Size

Cons: Semi-difficult to remove the grill???

Features

Applications: The Monitor Audio Radius 225 LCR loudspeaker can be used as a front, center, surround, or surround back speaker in your home theater system.

Two-Way Speaker Design: The Monitor Audio Radius 225 LCR loudspeaker features a two-way speaker design with one 1" C-CAM gold dome tweeter and two 4" C-CAM cone woofers. The 1" C-CAM gold dome tweeter is optimized to deliver the fines and widest performance within the compact speaker cabinet. It benefits from a more efficient rear-venting design, releasing air trapped and compressed at the back of the tweeter dome, and guiding it around the drive assembly to a rear-loading chamber. The 4" C-CAM woofers feature a large motor and voice coil for increased excursion, high power capability and reduced distortion. The C-CAM tweeter and woofers share an audible consistency producing a smooth transition of frequencies and a sense of realism and cohesion in the soundstage.

C-CAM Technology:  The 1" tweeter and two 4" woofers of the Radius 225 LCR loudspeaker utilize Monitor Audio's proprietary C-CAM speaker technology.

  • 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 Woofer: 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.

Single Through-Bolt Mount: The tweeter and woofers are fixed to the cabinet with a single through-bolt driver fixing mount. This single-through-bolt mount design provides mechanical de-coupling and enhanced midband clarity and resolution. The through-bolts also act as rigid cross bracing to give a very solid non-resonant cabinet.

HiVe II Bass Reflex Port: The Radius 225 uses a bass reflex cabinet with Monitor Audio's HiVe II port design for greater efficiency and bigger bass response from a smaller speaker. The HiVe II bass reflex port is shaped to have the same effect on airflow as a gun-barrel on a bullet. Rifled grooves inside the port help to accelerate the flow and reduce turbulence, so air moves in and out of the port more efficiently, for a faster more dynamic bass response.

Stylish Cabinet: The Monitor Audio Radius 225 features a beautiful precision cabinet in a gloss black, gloss white, or walnut lacquer finish. The cabinet's smooth rounded edges, silver trim, and metal mesh grille add to the style and look of the speaker.

Gold-Plate Binding Posts: The Radius 225 is fitted with gold-plated binding post speaker terminals that will accept bare wire (up 12AWG), pin-connectors, spade connectors, and banana plugs (single or dual).

Mounting Options: The Monitor Audio Radius 225 LCR loudspeaker can be positioned horizontally or vertically (the Monitor Audio badge on the grille can be rotated to suit orientation). Self adhesive rubber feet are provided to prevent movement due to vibration when using the Radius 225 loudspeaker on a table, shelf, or stand. The Radius 225 LCR can also be wall-mounted using the included bracket. A horizontal and vertical wall-mount template are provided to aid with installation.

  • Horizontal Dimensions: 24.0625" (w) x 5.5625" (h) x 2.9375" (d)
  • Vertical Dimensions: 5.5625" (w) x 24.0625" (h) x 2.9375" (d)
Note: The included wall-mount bracket adds 0.3125" of depth to the LCR speaker.
