Hello,
I recently purchased a UMIK 1 to tune my car audio system and I am still learning the ropes with tuning and SQ analysis. I have ESB 3.165 doors and ESB 3K UMA units (Mids and Tweeters combined) installed powered by two Rockford Fosgate P400 4ch amps. All signals and crossovers are from Apple Car Play on factory head unit through a MiniDSP C-DSP 6x8 processor. I have crossovers set at 120Hz, 500Hz, and 3500Hz with LR 24dB/Oct filters.
For the combined measurements (No subs) in the images attached below I used 64k FFT periodic pink noise in a RTA using the moving mic method. However there are +- 10dB discrepancies in the high frequency range which make me doubt the accuracy of these measurements.
Is the "comb filtering" of the high frequency range more likely to be an install related issue, or possibly a problem/common issue with my settings in REW?
