Setup & Use of PEQ

Option 2: Measure the Combined FR of the Speakers and Subwoofer using Excel Spreadsheet: To measure the combined FR of the front speakers and subwoofer (to include the digital crossover in your processor), connect your sound card output to an analog input on your processor. Make sure the analog input is configured to use the digital crossover between the speakers and the subwoofer. Use the Excel spread- sheet named Speaker_And_Subwoofer_Combined_Frequency_Response (link provided above), which will plot the frequency response from 11.2 Hz to 201.6 Hz. Input your raw (direct read) values from your SPL meter into the green band of frequencies in the Raw SPL Data worksheet, and the Frequency Response worksheet will plot the combined FR of the speakers and subwoofer.

Adjusting The PEQ: Identify the largest/widest peak in the response and target it for reduction with the PEQ control. When making adjustments to the PEQ control, there is no need to re-plot the entire FR for interim adjustments - simply re-plot the affected section of the curve to verify your PEQ adjustments are having the desired effect. When you are done making adjustments, you can re-plot the entire frequency response to obtain a final curve.
