OUR VERDICT - Back in the days before anyone had ever heard of ‘designer’ products and home cinema came with wardrobe-like enclosures and racks of chunky boxes, Monitor Audio invented the Radius Series of stylish and versatile speaker systems. So radical was the idea that it changed expectations of home entertainment forever. Now, energised by their latest driver technologies, the next generation of Radius has arrived, complete with new models, greater versatility and higher, wider, deeper sound.
When most people think of home cinema they worry that this means they will have to have big dominant speakers that go against the Feng Shui of the chosen room. Thanks to the engineering prowess of the Monitor Audio designers you can have discrete room filling sound thanks to the Radius range.
The four Radius 90 satellite speakers ensure that you get an even tonal balance as sound effects pan around your room, whilst the Radius 200 centre channel speaker ensures that dialogue remains front and centre even when the action gets heavy. To reinforce the low end Monitor Audio have included the Radius 390 subwoofer complete with adjustable sound modes and assertive sound from a modest cabinet. All of this combines to make the R90 HT1 from Monitor Audio the go to lifestyle speaker package at this price point. - Thoroughly Recommended.
Designed for rack or shelf mounting in a home cinema or surround sound system. Placed front and centre in a serious AV system, twin 4" C-CAM mid/bass drivers astride a 1" C-CAM tweeter result in the compact Radius 200 anchoring the entire sound field with life-like fidelity. The Radius 200 features dual C-CAM bass drivers with a C-CAM tweeter in an MTM style configuration.
Radius bass drivers have concave cone profiles, introduced by our top-of-the-range Platinum speakers and applied subsequently to Gold GX. Extensive research and FEA modelling have allowed us to perfect the relationship between the radiating diaphragm and its motor design, introducing larger motor sizes and voice coils for increased excursion, higher power capability and reduced distortion.
C-CAM Gold Dome tweeter - optimised to deliver the finest and widest performance within the compact Radius cabinets. 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.
HiVe II port design - Straight from Platinum’s design blueprint, the HiVe reflex port makes its Radius debut. It’s 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.
Single through-bolt driver fixing provides mechanical de-coupling and enhanced mid-band clarity and resolution. The through-bolts also act as rigid cross bracing to give a very solid non-resonant cabinet.
Radius 90 - Single point ¼” x 20TPI wall fixing. Use the optional Monitor Audio speaker mount or any standard wall bracket. Optional floor-stand with internal (pre-wired) cable management system.
Radius 390 subwoofer comprises of colour-coded 10" C-CAM active/ABR drivers, powered by a 200 W Class D amplifier. Enjoy rapid EQ optimisation from Impact, Music and Movie settings, and system automation via the 12 V trigger.
