Promising even more style, practicality and performance, RadiusHD is a décor-matching series of ultra-compact satellite speakers that replaces the original and radical Radius range. Brilliantly conceived and beautifully crafted, Monitor Audio's wholly innovative Radius concept miniaturised the virtues of elite hi-fi engineering without shrinking sound quality. By harmonising elegant, ultra-compact design and great sound, Radius systems rendered a generation of cheap plastic systems obsolete.
With improved styling, finishes and even better performance, RadiusHD marks a comprehensive upgrade of a classic lifestyle design. Tuned and optimised by the latest computer modelling techniques, the nine-strong HD range blends better dynamics with wider bandwidth to add explosive force and detailed subtlety to film sound and music. Radius HD offers improved dynamic performance and extended bandwidth by virtue of a further refinement of MA's Metal Matrix Polymer (MMP® II) for the bass drivers and Ceramic-Coated Aluminium Magnesium (C-CAM®) technologies for the tweeters. The five Radius HD satellites are designed to operate perfectly in LCR positions; there’s also an ultra-slender floor standing model, two active subwoofers (8" and 10") and a combined three-channel A/V speaker the 'Radius One HD', which is perfect for ultra-discreet applications.
By offering a wide choice of compact lifestyle speakers in as many as five décor-enhancing lacquer and real-wood finishes, complete with versatile easy-install bracket systems and floor stands (model specific), the RadiusHD series makes it easier to custom fit high quality sound to every room in your home.

"...And oh those tweeters! Monitor Audio have a had a lot of experience with metal domes, and these were a joy to listen to...the MA’s had speed, grip and insight in spades – without a hint of harshness. It’s safe to say that I can’t remember hearing a better treble performance from a pair of £300 loudspeakers..."

Rich Sound in a Small, Elegant Speaker System
"...the finely polished real wood veneer, gold-plated binding post speaker connectors and excellent fit and finish, the mini Monitor system exudes quality...the Monitor Audio R90HD speakers sound like a larger bookshelf speaker and comfortably blend into almost any room decor...the subwoofer sounded full and deep...the mini-Monitors easily reproduced the wide dynamics...the R90HD mini Monitors will decieve the eyes, but not the ears. They're small enough to be virtually invisible but with their fine finish, you'll want to place them where they can be seen and appreciated...with sound that matches and exceeds many bookshelf speakers...I heartily recommend them!
