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
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.
