Questions and Answers
How do The Radia Series components solve specific acoustical problems?
Conventional point-source speakers radiate sound in a spherical pattern, thereby directing substantial
acoustical energy outside of the immediate listening area and causing undesirable ceiling and floor reflections.
•
Because of their line-source operating principle, the ribbon component in each Radia Series speaker
directs sound only into the listening area, eliminating ceiling and floor reflections. This substantial
advantage is made possible without the use of multiple tweeters or other controversial techniques.
•
The Radia Series systems guarantee high power handling to above 500 watts per channel, making them
very useful for full-sized home theater installations. High output capability means that The Radia Series
speaker systems also eliminate inadequate image size and inadequate playback volume distortions.
•
Conventional speaker systems attenuate (reduce volume) at a rate of -6 decibels (a measured
reduction of acoustic power of 4 times) every time the distance to the speaker is doubled. The Radia
Series line-source ribbons attenuate their volume over distance at half this rate, or -3 decibels per
doubling of distance. This allows for much more consistent coverage and a significant reduction of
listener fatigue due to both excessive volume close to the speaker and insufficient volume farther
back in the audience. Conventional speakers cannot deliver the resulting sonic realism.
•
The Radia Series line-source speakers also operate as one-way speakers above their bass crossover
point, thereby achieving the ideal of coherent, consistent amplitude (loudness) and phase response.
