Transform the sound in any space.
Anthem Room Correction (ARC) is our proprietary acoustic calibration technology, engineered by the same team behind Anthem’s award-winning audio systems. ARC delivers the sophistication of a professional audio lab directly into your home, enabling your system to perform at its absolute best — regardless of room size, shape, or layout — without requiring an engineering degree.
ARC is more than correction; it’s a complete approach to sound, combining science, precision, and ease of use to help you hear music and movies exactly as the creators intended.
How ARC Works
ARC consists of two core components
ARC-Compatible Products
Select models from Anthem, MartinLogan, and Paradigm.
The ARC Measurement Kit
Includes a precision-calibrated microphone and software that measures your room, calculates correction curves, and uploads them directly to your system.
Our software suite includes ARC Genesis for Mac and Windows — free to download. ARC Genesis also features a full-function demo mode, allowing you to explore its capabilities before making any changes.
With ARC, the complex work is handled by our engineers, while you benefit from audible, measurable improvements. It’s powerful enough for professionals, fully customizable, and yet intuitive enough for anyone to use.
Using ARC
Setting up ARC is straightforward:
In minutes, ARC analyzes your speakers and subwoofers, applies room correction, and calculates optimized bass management, delivering accurate, balanced sound throughout your listening area.
Bass Management
Low-frequency content can challenge most speakers. Bass management directs deep bass to your subwoofer, relieving strain on your system’s woofers, crossovers, and amplifiers, while improving overall performance and impact.
ARC measures the full acoustic response of your speakers and subwoofers and provides recommended bass management settings. This ensures tight, controlled, and natural bass, seamlessly integrated with all channels, including LFE (.1%) tracks in home theater setups.
Room Gain
Room gain is the natural reinforcement of upper- and mid-bass frequencies caused by room boundaries — floors, ceilings, and walls. Our brains perceive this effect subconsciously; removing it entirely can make a system sound unnatural.
ARC preserves the beneficial effects of room gain while correcting unwanted acoustic anomalies, giving your system bass that feels both natural and controlled, and music that sounds as it was intended.
Room Correction & Standing Waves
Every room influences sound. Reflections, resonances, and standing waves — caused by walls, ceilings, floors, furniture, and windows — create peaks and dips that vary across listening positions. Even the best speakers are affected, resulting in boomy or weak bass, less natural voices, and reduced clarity in dialogue.
ARC measures the output of each speaker relative to your listening position and applies custom correction curves through advanced digital signal processing (DSP). This approach smooths frequency response, tames standing waves, and preserves beneficial acoustic characteristics, providing consistent, accurate sound throughout the room.
Equalization in the Modern Era
Once, equalization was feared. In the analog era, early room correction systems were rudimentary and often introduced distortion or uneven results. Today, ARC Genesis uses high-speed , advanced digital filters, and precise crossover technology to apply corrections safely and accurately. Modern equalization is essential for natural, balanced, and high-fidelity sound.
Speaker Safety
ARC is engineered to protect your speakers. Boosts are limited to +6 dB, preventing overdrive, while reductions on peaks are safe and risk-free. For rooms with severe dips, repositioning speakers before running ARC often yields the best results. In short, ARC corrects intelligently while ensuring your system operates safely and reliably.
Who Is ARC For?
ARC Genesis is designed for both consumers and professionals:
Auto Mode:
Simplifies setup — answer a few questions, run the measurements, and ARC automatically calculates and uploads room correction and bass management settings.
Professional mode:
Provides installers and enthusiasts full control over every parameter, allowing granular customization before uploading corrections.
From a straightforward 2-channel stereo to an elaborate 9.4.6-channel home theater, ARC adapts to your system and space, delivering exceptional, reliable performance for anyone who demands perfect sound.
Anthem Room Correction puts the power of a professional audio lab in your hands — so your system can sound its absolute best, anywhere.
