What customers say
Audiophiles overwhelmingly praise the ARC Calibration Microphone Kit as essential for unlocking the full potential of MartinLogan and Anthem systems. The core theme is the dramatic improvement in sound quality achieved through the Anthem Room Correction system. Users report superior bass integration, elimination of room anomalies, and a significantly clearer soundstage after calibration. While the process involves detailed measurement, the powerful ARC Genesis software offers precise control, leading to professional results. Despite the proprietary nature limiting its use to compatible components, the consensus is that the tangible, audible fidelity gains strongly justify the investment. This kit is viewed as a high-value necessity for achieving reference level audio performance.
Know before you buy
This kit is designed specifically for MartinLogan subwoofers that feature built-in Anthem Room Correction (ARC) technology. You should check your subwoofer's user manual or the product page on the MartinLogan website to confirm that your specific model supports ARC calibration.
The ARC system measures the acoustic response of your room and identifies frequency peaks and dips caused by your walls and furniture. It then applies digital signal processing to smooth out these deviations, resulting in tighter, more accurate bass that is free from the 'boominess' often caused by room reflections.
Yes, you will need to download the ARC software from the official MartinLogan or Anthem website to your computer. The microphone connects to your computer, which then communicates with your subwoofer to perform the measurements and upload the correction profile.
No, this specific kit is designed exclusively for calibrating compatible MartinLogan subwoofers. It is not intended for full-range speaker calibration, which typically requires a different microphone and receiver-based ARC setup.
For the most accurate results, you should use a tripod or the included desktop stand to keep the microphone perfectly still at ear level in your primary listening position. Holding the microphone by hand can introduce vibrations and movement that will compromise the measurement accuracy.
