I just got my Topping DM7 8-ch DAC which resolves my previous clock drift issue while using 2 distinct async DACs.
I am reviewing the subwoofer integration REW charts, and I need some advise here.
The crossover point is set to 80Hz.
The charts below show 3 sweeps from 10Hz to 2kHz with different subwoofer delays, namely -10ms, 0ms, and +10ms.
First up is the frequency response chart: note that the -10ms has a heavier dip in the red circled area.
Next up is the step response chart:
In your opinion, which subwoofer delay is preferred?
-10ms? because the peak is nearer to the start of the step?
+10ms? because the SPL dip is less?
Second question -- should I push it even more to -20ms (which is the max the software can do) ?
Thanks in advance for your feedback.
