Radius HD 5.1 System Review
“The degree to which the slender R270HD towers and compact sub opened up my room was astonishing. I saw portions of my walls I haven’t seen in two years.”
“I was immediately struck by the clarity and crispness of the Radius HD’s tweeters. Delicate high frequency sounds like the glass breaking as the Comedian goes through the window in the opening scene and the water rushing off Nite Owl’s Owlship were extremely detailed, without being overbearing, sharp or piercing.”
“The R225HD centre channel in particular impressed me, delivering true, natural sounding dialogue, without any of the characters sounding boxed-in or tinny.”
“…very even, consistent sound field, with panning sounds being extremely consistent and not changing in tone as they moved around the room.”
“The level of detail the Radius HDs displayed, especially in the high frequencies, really brought the award-winning mix of music and effects present in this album to life.”
“…if I had been wearing a blindfold during testing, not once in a million years would I have guessed that these speakers were as small as they actually were. I found their performance to be impressive both with music and film.”
