Front Panel Controls

The IW-155 LCR is equipped with intuitive front panel controls that allow for precise audio customization.

  • High-Frequency (HF) level control lets you adjust the tweeter's output to accommodate varying room acoustics, ensuring optimal sound quality in any environment.
  • Boundary control allows for adjustments to the upper-bass/lower-mid response, effectively correcting for "boundary gain" when the speaker is placed too close to a corner. This level of control ensures a tailored audio experience that suits your unique listening preferences.
