The spectrograms are the more interesting result of the 2 graphs.Thank you very much for posting this! Very interesting. Impressive in many ways. But wouldn’t one be able to achieve much of the same result just be some eq in the bass and taking down the extra energy in the peaks? It seems strange to me that they had that big peaks using multiple subwoofers... they can’t have used any eq before putting the Avaa in place it seems.
