Sound Blaster Roar SR20A White Paper – Evolution, Concept and Tech Overview
TeraBass
What is it?
TeraBass is a feature that intelligently compensates the loss of perceived loudness in bass
during low level playback without artificially over accentuating bass levels. TeraBass
processing will intelligently increase the loudness of bass at low to medium levels and
this processing will decrease as master volume level increases until near or at maximum
output where no processing will be applied.
Why the need for TeraBass?
Because of the dynamic nature of use. Outdoor? Bedroom? Nearfield? Midfield? or
simply personal preference.
Like our in-house reference systems, the Roar is tuned to be accurate, balanced, and well
defined while delivering full spectral output at maximum levels with minimal or no
compression. (NOT common in many battery operated portables).
Like a professional loudspeaker, the SR20A is designed to go low and accurate. Most
loudspeakers in this class tend to artificially boost low frequencies making the playback
boomy and lacking midrange. Bass from the SR20A is tight, deep and uncolored.
Midrange is neutral and full bodied.
The SR20A is designed for use just about anywhere. However, when it is played back at
low to medium levels for Eg late night listening, the listener may not perceive bass that
well and needs that improved subjective musicality. TeraBass will help add excitement
to the playback.
TeraBass will also compensate for the loss in bass when the loudspeaker is placed in-less-
than ideal acoustical environments.
Our research has shown that due to these dynamic usage conditions, the need to be able
to turn ON and OFF TeraBass is critical.
