Blending compact size with great sound and seductive styling, the Radius R90HT1 system will add explosive audio dynamics and glamour to your home cinema, punctuating the action on screen with pin-point imaging and enveloping surround effects.
Product Ref: 206582
"it’s beautifully made, offers powerful, polished sound quality and looks stunning - pretty much everything we look for in a speaker system. If you’re looking for a speaker system on a £1,500 budget then stick the R90HT1 on your shopping list pronto. We’ve heard some pretty special speaker systems of late ... but the Radius trumps them all"
"This system mixes both eager dynamism and impressive scale with poise and insight. Detailed soundtracks are treated with respect, while dialogue from the Radius 200 centre enclosure is full-bodied"
"if you yearn for a discrete 5.1 set-up, this should be on your radar, because it’s a remarkable success…integration between fronts, rears and the sub is seamless. The surround field is gapless, effects flow between channels effortlessly and you’re immersed in the action"
Blending compact size with great sound and seductive styling, the Radius R90HT1 system will add explosive audio dynamics and glamour to your home cinema, punctuating the action on screen with pin-point imaging and enveloping surround effects.
It combines all the virtues of Monitor Audio design in a beautifully space-efficient system, precision engineered in a choice of finishes and with stand and wall-mount options to accommodate a range of installation possibilities and room colours.
From four bijou Radius 90 satellites and a Radius 200 centre channel speaker, you’ll experience the life-like accuracy of multiple, matched C-CAM driver systems, underpinned by the prodigious bass output of the miraculous Radius 390 sub. Equipped with twin 10” C-CAM active/ABR drivers of cool Class D power, the low-profile Radius 390 cube is optimised by the latest DSP technology to generate an extraordinary size-defying blend of bass depth and slam.
Expertly tuned to deliver the full-frequency impact of today’s high definition soundtracks, the R90HT1 gives you luxury lifestyle design, easy-to-install versatility, exceptional room-friendly aesthetics and the immersive audio quality that all home cinema enthusiasts crave.
In MTM style configuration - Radius features all new bass drivers with 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 new radiating diaphragm and its motor design, introducing larger motor sizes and voice coils for increased excursion, higher power capability and reduced distortion.
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.
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.
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.
For open environments sound quality can be further enhanced through the use of a sealed ABR (Auxiliary Bass Radiator). The ABR works like a piston moving back and forth generated by the movement of the air via the motion of the mid/bass driver inside the sealed cabinet. This makes the ABR ultimately act like a conventional port resulting in superior low frequency punch and extra penetration whilst keeping the elements at bay.
