Stand-alone room correction kit for the best bass possible. Works with BalancedForce 212, BalancedForce 210, and Dynamo (600X, 800X, 1100X, 1500X, and 1600X). Even when a MartinLogan subwoofer is ideally placed, the dynamics of each listening environment present a unique challenge for bass performance. The Perfect Bass Kit (PBK) learns vital information about your unique space, transforming the subwoofer’s performance for perfect bass, every time. PBK Stands Alone in Optimizing Bass Performance The PBK system employs Anthem’s ARC Genesis software and your PC, connected via USB to a microphone and your MartinLogan subwoofer, to identify problem areas in your listening environment. ARC Genesis processes information from multiple data points and configures the optimal solution, achieving pinpoint-accurate room response. Multiple Microphone Measurements Ensure Accuracy Current room equalization systems are capable of taking a single measurement at the primary listening position. ARC Genesis software utilizes numerous measurement points, at least five—but up to ten—individual data positions, allowing ARC Genesis to learn the unique characteristics of your room. PBK is Audiophile-Accurate PBK employs Anthem’s ARC Genesis software and your PC's processor to calculate correction curves for each measurement point, substantially minimizing the rounding errors of less sophisticated "calculators," like those used in standard room equalization systems. Additionally, ARC Genesis software is capable of calibrating itself to the unique performance characteristics of your microphone.
