Anthem STR - ANTHEM ROOM CORRECTION (ARC); How ARC Optimizes Sound

19
For anyone reading this, the experience of walking into a room and being struck by the dramatic change in its sound
after carpet and furnishings have been moved out is probably a familiar one. It may also bring to mind the varying sound
character from one room to the next according to its size and structural qualities.

speakers, Anthem Room Correction measures the output of each one relative to the listening area then through a
special series of calculations adjusts the output accordingly. Its target responses have a psychoacoustic basis from
research results, not just theoretically ideal curves.
While removing resonances and modal peaks common to the measurement positions, ARC also distinguishes and

in-room response, which normally includes this room gain to varying degree. It is one reason that a speaker sounds
