The Platinum In-Wall 3G comes with a pair of switches to adjust the mid and high frequency levels. These are located on the front of the cabinet at the bottom (when positioned vertically) and adjustment will either boost or attenuate the mid-range and tweeter levels by +/-1dB. There are separate switches for each unit, and experimentation is recommended to achieve the perfect combination for your environment.
