 Yeah, and these will usually be caused by room modes. The theory is that if you apply an EQ filter with the same Q and opposite gain of a room mode, it will completely counteract the effect of the mode in both amplitude and time. I did a post on this here that you can read and see what you think. REW attmpts to match all room modes with its filter recommendations.
I think you're on the right track, but I also believe that the response should be smoothed as much as possible in all domains including amplitude, but that's personal choice. Certainly you don't want to reduce the decay until it sounds like an anechoic chamber, but if the decay is too long it also won't sound right.

I think OvalNut has it right. It's ok not to be flat. It's ok to have some reverb too. I did a full LF EQ (total of 8 filters across 3 speakers) I set the Target Level fairly high (80db) so it wouldn't be too agressive with filters. It sucked the life out the whole system. No LF impact at all now. The filters were few but fairly large. I started to do a target of 85 but the filters are still pretty large.
I know there is a lot of debate on this. But you want some reverb but too much is boomy. Not every large peak will ring. I just want to go after the ones that ring. Goals might be a little different for Music versus HT. If a an explostion isn't "flat" in a movie does it really matter !!
