Product Description

Priced per pair - The NN Z are made to order and 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 created by the speaker coils themselves.

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

Typically expect -

  • Wider stereo imaging
  • Better Instrument separation
  • Less midrange muddle
  • Better tonality

* Note - All systems do react differently to filters, therefore, results may vary. We all have different amounts of noise and at different frequencies. The more noise you have the bigger the impact the filter will have.

* Please allow a burn in period of at least 100 hours
