Just an observation. Modern sound reinforcement is amazing compared to what was available several decades ago. However, I am noticing that there is a tendency now to have an absolutely huge and ultra low bottom end, far exceeding the musical range of low notes. Do we really need to feel like we are being kicked in the pancreas in order to enjoy music? The real disappointment is that there is a lot of information in the frequencies just above that range that is now missing or overshadowed by this fascination with the ultra low. Human hearing can barely discern most of what is going on at 30-40Hz afaik. It just seems like we are living in an era where with all this great equiment the prevailing wind is to make live music sound more and more like a DJ shaking the house, or a car stereo disturbing the neighborhood. I don't mind loud. I just want to hear ALL the musical frequencies, and not just the super low and the upper mids and nothing in-between.
