That makes me wonder if DIRAC is setting mine right before doing room treatment I was seeing high crossovers in my heights and surrounds. Now I'm seeing 70hz on all speakers, they are all RSL in wall and in ceiling the in ceiling are dual 4.5" drivers and in walls are dual 5.25" drivers does this seem right? The in ceiling speakers have a freq response of 65 - 20 000hz and the in walls are 48 - 20 000hz. Does having them all set to 70hz make sense?
It doesn't matter what the frequency response is from the manufacturer (to some degree). What matters is how good the response is in your room and at the max volume you'll use. For me, that's 0dB. Do I watch media at 0dB? Only really old movies that aren't mixed well. Most everything else I can leave at -7dB or less.
But even at listening level, there are some demos that clearly cause that popping sound for me. If I listened softer, they sound fine.
What you want to do is try out those demos yourself at volume. Pick a slightly higher volume (so you have some headroom) and see how they sounds with a 70Hz crossover.
There's a Dolby 747 airplane overhead demo. That's a really good one to test with. Another one is the Unfold demo that has 4 words at the end (not 3). The one with 4 can cause bass hits in the heights.
Both of those had popping at -14dB for me with anything lower than 120Hz on my heights. My heights are Polk Reserve R900s.
