The Frequency Shaping Module, or "FSM" was designed to be used in conjunction with the E39 Passive Crossover Network to provide a more relaxed listening experience.
If you own a v1 E39 PCN and prefer a slight attenuation of the mids and an overall calmer presentation, the FSM is designed specifically to do just that. The v1.5 E39 PCN will have the FSM circuitry integrated into the board. With an original E39 PCN and this module, the listening experience will be comparably the same as a v1.5 E39 PCN.
Although the FSM was designed for the E39 PCN, it modifies a specific frequency band and may be installed on any 10 channel German Audio Specialties passive crossover networks.
