Key Features
The Monitor Audio Radius One system creates a unique twist on the traditional 5.1 speaker package. Instead of three separate speakers at the front for centre left and right duties, these are combined in the compact wall-mountable Radius One. Combine with the powerful 380 subwoofer and compact 45 satellite speakers for surrounds and you have a surround system which harbours Radius's famed sound quality but in a much reduced footprint.

The Monitor Audio Radius One system creates a unique twist on the traditional 5.1 speaker package. Instead of three separate speakers at the front for centre left and right duties, these are combined in the compact wall-mountable Radius One. Combine with the powerful 380 subwoofer and compact 45 satellite speakers for surrounds and you have a surround system which harbours Radius's famed sound quality but in a much reduced footprint.
The original Radius soundbar was a real winner but this updated version includes new upgraded drivers which feature Monitor Audio's C-CAM technology and has been slimmed down for a sleeker look which is also suitable for wall mounting. A dedicated wall bracket is included with the Radius One, along with mounting template for easy installation, although the speaker is equally at home on a cabinet or shelf.
The Radius 45 surround speakers are beautifully finished compact cubes which can be wall mounted with the optional Monitor Audio MASM wall bracket or any mount with a ¼" thread (20TPI), they can even be used with the Radius floor stands. The entire system is underpinned by the 380 subwoofer which utilises a dual driver design to generate a seismic bass foundation for films and music.
Part of the beauty of the Radius speaker system is that the various models can be combined in many different configurations, including colour variations, there's no reason you cannot have a black Radius One used with white Radius 45 speakers, or change the Radius One for three separate Radius 225 speakers, if you're looking for a slightly different than standard solution then call our sales team to discuss your requirements.
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.
