reducing peaks question..

[tdamocles]

At what point in peak reduction in a freq. response start to degrade the signal? 5db, 10db, 15db reduction in a peak or doesn't it matter too much as long as I can turn the sub amp up to compensate?

The reason to reduce a peak is that the room interaction at that frequency demands it. If you have a 15dB peak at 50hz, and you introduce a filter of -15dB at 50Hz of the same bandwidth, the room will bring that frequency back level with the rest of the response. Why would you turn up the amp to compensate?

When a few peaks are in the frequency response curve and a few cuts are done to overcome them the overall volume is reduced thus the reason for turning up the amp to compensate for the loss, correct?

Yeah, I guess if the peak(s) were wide enough to modify the overall listening level you would want to bump up the sub amplifier to compensate. Makes sense.

Just say that you have 3 peaks and needed to cut them 10db each, would that degrade the output signal at the sub at all?

No, it should make them just right. If your final, in-room frequency response measures near your target, you will be doing well. You don't want +10 dB humps -- that's degrading the experience by artifically boosting that frequency due to the room or whatever.
