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 black, 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.

Speaker Enclosure Type
Infinite baffle (sealed)
Type of speaker enclosure. Infinite baffle cabinets are sealed and so are often less fussy about placement. Usually they do require a little more power to drive, though. Bass reflex speakers are usually more efficient than infinite baffle designs but may require more care in terms of placement. Rear port designs, in particular, usually need at least 15-30cm (6 - 12 inches) between them and the wall behind, for a balanced bass response.
