Transform the sound in any space.

Anthem Room Correction (ARC®) puts the sophistication and power of an advanced audio lab in your hands so that you can achieve perfect sound at home. Our PhDs did the hard work, so you don’t need an engineering degree to use it. ARC is sophisticated enough to produce real results that you can hear, easy enough to be used by anyone, advanced enough to allow you to customize the settings, and professional enough to give you the kind of results you’d expect from software and hardware costing thousands of dollars.



Why do your listening room and speakers need correction?

The most significant detriment to the sound of an audio system is almost always the room it resides within—especially true in the realm of bass. Even in a professionally treated sound room, bass can quickly become boomy or anemic. Anthem Room Correction helps audio systems sound their best in any space. ARC offers a robust suite of tools to tame your wild sonic frontier, whether you have a tricked-out home theater, a traditional living room with carpet and thick drapes, or a modern floor plan with large open spaces and acoustically reflective furniture and windows.

Your room affects the sound.

Have you ever tested the acoustics in an empty room by whistling or clapping? It brings to mind how sound is affected by a room’s size, structure, and contents. Even when using optimally positioned speakers of exceptional quality, the room negatively impacts sound quality considerably. Surfaces such as windows and furnishings and the geometry of the walls, floor, and ceiling add unwanted resonance and coloration, making the bass either boomy or less punchy, voices less natural, and the dialogue less intelligible. The effect on frequency response is typically ±6 dB in the midrange and ±10 dB at low frequencies.

ARC to the rescue.

To compensate for this and to optimize the in-room response of your speakers, Anthem Room Correction measures the output of each speaker relative to the listening area then, through a series of calculations, adjusts its output. Not only does ARC correct peaks and dips in a speaker’s frequency response, but it also preserves the beneficial acoustic attributes of a room—attributes based on proven psychoacoustic science (the study of how humans hear and experience sound).
