Making its European show debut at ISE 2009 is Radius HD, a new decor-matching ultra-compact sat/sub range of speakers, which replaces the very much original and acclaimed Radius series. Utilising many innovations developed for Monitor Audio’s award-winning high-end Platinum speakers and available in a range of smart real wood and lacquer finishes, the sleek new Radius HD designs benefit from flush mounted grilles to present a clean, elegantly contoured look.
