Compact, good-looks meet quality sound, with the Monitor Audio Radius 45.

The most discreet speaker

At just 10cm cubed, the Monitor Audio Radius 45 is one of the most discreet speakers around. The compact size makes it ideal for a wide range of uses, from desktop speakers, background music in a multi-room set-up to satellite speakers in a surround sound system. A choice of gloss black, satin white or walnut finishes means there's a style to suit your decor.

Flexible positioning
Compact enough to be placed on a mantelpiece, bookshelf, window ledge or desk, the Radius 45 can also be wall-mounted with the optional MASM mounts or stand-mounted via the optional Radius stands.

Spacious sound
The Radius 45 uses an unconventional speaker pattern to give a spacious sound quality. By placing the gold C-CAM tweeter at the rear of the speaker, the sound is dispersed over a much wider range giving the Radius 45 a much more enveloping sound than you'd expect from such a small speaker.

Monitor Audio quality
They may be small, but that doesn't stop the Radius 45s from using top-quality Monitor Audio speaker units. The gold C-CAM tweeter is similar to those used in full-size Monitor Audio speakers and gives a similar ideal balance of smoothness and detail. The main MMP (Metal Matrix Polymer) speaker unit offers a highly realistic mid-range and punchy upper-bass - just add a subwoofer for true bottom end rumble.

Whether its home cinema or hi-fi, multi-room or desk-top, the Radius 45 has all the qualities you could ask for in a compact speaker.

Rated 5 out of 5 by from So much from so little Fantastic little gems. The sound is amazing for something not much bigger than a Rubic Cube. So easy to mount on the wall with dedicated brackets.

Rated 5 out of 5 by from satellite rear Bedroom 5.1.2 set up, these are used for the rear satellites as I have a small bedroom and dont have room for bigger rear surrounds but these are better than expected for the size. Clarity is good and they look decent too. Tweeter in the back I found a bit odd but it does work...Very good if you need to save space

Rated 5 out of 5 by from Great sound and beautiful gloss black finish. I bought these as rear surround speakers in a 9.1 Monitor Audio system. Very happy with the sound and very easy to mount with the Monitor Audio brackets. Excellent service as usual from Richer Sounds.

Rated 5 out of 5 by from Great sound Very nice looking speaker perfect for if you have limited space and great sound look great mounted in the corners of a room

Rated 3 out of 5 by from Look good, but... Not convinced yet on the sound quality. Maybe because my front speakers (Bronze 2) are so good these get pushed, literally, into the background
