HF Level

Below and overleaf are listed our recommendations for different listening distances and placements. However, there is not per se any specific value that is right or wrong. Please use your own preference, discernment and hearing as guide. It is right when it sounds right.

To increase the upper midrange and lower treble frequencies compared to whatever you have currently installed use a combination marked with a greater dB value; to decrease the upper midrange and lower treble frequencies use a combination marked with a lower dB value. Should you, for any reason find the existing adjustment range insufficient please contact us for further options.
