Monitor Audio Radius 45 Overview
You can also use a pair of R45s with the R360 Series 2 powered subwoofer to create a surround-sound home cinema system. Together they provide powerful dynamics and a smooth, revealing midrange, but the system's highest treble frequencies can become overly prominent, disrupting imaging and making fast-rising transient sounds edgy or harsh.
However, this is a problem that can be mitigated with proper break-ins and a good room EQ. It's also worth pointing out that the low bass in this system can sometimes sound loose and diffuse, so those who like their low-frequency effects to be crisp and punchy may not find this as pleasing. Still, for those who like their high-frequency details to be rendered with a bit of larger-than-life drama, the Radius 45 is an excellent choice.
Monitor Audio Radius 45 Features
They come with cast metal wall-mounting brackets, which are a nice touch. And they leverage innovative floor-level connections for a luxury wire-free look, too.
A 3" MMP II mid-bass driver and rear-firing 3/4" C-CAM tweeter deliver excellent bass and midrange response. The combination is perfect for surround sound duties in a small room or partnered with the R360 Series 2 powered subwoofer for explosive stereo in an ultra-compact system.
This little speaker's size-defying performance comes from a rear-firing gold C-CAM tweeter, which spreads and magnifies the sound around the room to create a huge encompassing surround effect. It's similar to Monitor's full-size C-CAM tweeters, and it offers a great balance of smoothness and detail.
The Radius 45 is an ideal option for home theatre systems and music fans alike. Its small size makes it an easy addition to any setup, and it delivers a wide range of music genres.
It's designed to work with a wide range of audio sources thanks to its gold-plated binding post terminals, which accept banana plugs, spade connectors, and bare wire. Its compact size also allows it to fit into smaller spaces, making it an ideal choice for apartments and homes.
The single through-bolt driver fixing is an excellent feature of the Radius 45, which helps to ensure that it provides consistent and accurate performance. It also provides mechanical de-coupling properties that enhance mid-band clarity and resolution.
