How to get the impact of a live concert?

In the early 80s I stuck 300 watt 15" bass guitar speakers in my Altec A7s...either JBLs or Electro Voice ...now THAT handled the thump. The "phased array" stuff you hear in most large concerts are interesting designs...usually stacks of class D self powered boxes with a couple of beefy 10s and one or two horn drivers in each, along with high power subs with 15 or 18 inch drivers. Much more bang for buck compared to the older stuff, and about 10 times the power.

A bottle of Boone's Farm and a hit of orange sunshine.

Now that's impactful

Woo hoo

WOW! Did that bring back some memories!

It's all about physical compression that happens in the speakers and the room itself that reveals playback vs. live experiences to our ear/brain and there is simply not much we can do about it. It's simply physics that imparts this limitation. Loud won't cut it, it just exacerbates the compression factor. Every room and speaker system has an optimal or maximal loudness level beyond which this compression just increases (usually experienced as "beaming" from the tweeter/midrange drivers). Most speakers have an enclosure or driver limitation, or both, beyond which compression increases logarithimcally and again, there's nothing we can do about it. Some absorption can help reduce phase cancellation and increase dynamic range in the room, but again, only so far.

I have simply accepted this and have learned that if I want live, I go see and hear live.

Hey, sitting here listening to a live recording of Black Sabbath, i have no
problem with not actually being there, at least with my eyes closed.

It's really kinda silly some of the things we audio kooks might sweat about.
