NN Z Speaker Purifier / Filter

The NN Z is designed to connect across your speaker terminals. They work by filtering away high frequency hash that is picked up via the speaker wire, internal speaker wiring and also effects created by the speaker coils themselves (counter-electromotive force). The aim is to absorb some counter-electromotive current and reduce the fluctuations in speaker impedance characteristics, particularly in the mid to high ranges. This makes it possible to drive the speaker more faithfully.

The NN Z helps deliver a three dimensional image and offers a darker background along with a much lower noise floor.

Please note – All systems do react differently to filters. We all have different amounts of noise and at different frequencies + speaker and amplifier setups differ greatly. The more noise you have the bigger the impact the filter will have.
