Yes, but the peaks are also coming down in level! So the net result for both the peaks and the nulls is a response that's closer to flat.

I never said "bass traps are the ultimate solution for all room problems." But of course we can have a useful discussion!

I'll go first:

In your opinion, how skewed a response is acceptable, and how much ringing is acceptable? If we can agree initially that the ideal goal is perfectly flat with no modal ringing - just as we expect from every other piece of "gear" in the playback system - how else would you improve the response and ringing if not with bass traps?

Now look at the two LF waterfall graphs below. The top one is the RealTraps "lab" room empty, and below that is the same room with a bunch of bass traps. The graphs are not normalized as are some of the graphs I've posted in the past, so in this case you can easily see exactly what has changed. Now, where do you see a null becoming worse, or wider losing more content, after adding traps? If anything, the null below the 92 Hz marker has become narrower, no?
