I have KS10 and self-program. The target gains are missed around 4KHz due to the feedback threshold limiting the gain. So I have added overtuning to raise the feedback threshold and allow more gain at these frequencies. I am currently testing this. See before and after snapshots attached.
My question is regarding what downsides there are to this (apart from the obvious increased risk of feedback) and if there are any alternative approaches. I have a 3mm vent in the cShells and would appreciate comments on whether that is too large for my loss and a smaller vent would be better.
Which approach is liley to be better for me (smaller vent vs overtuning)?
