In principle you can also use a phased array to remove the reverb. I'm not aware of any non-academic implementations though.

- kimburgess 4y agohttps://holoplot.com/ https://holoplot.com/ give a two dimensional array. The hangs of speakers that you see at most concerts are a line array, and within each of them will be an array of transducers that control the pattern of the individual cabinet (eg cardioid subs. You'll also quite see digitally steered columns in a lot of spaces these days too. None of these remove the reverb, but they do provide control over where energy is directed to minimise it occurring in the first place.
- hansvm 4y agoNeat! "All" you need on top of that for reverb cancellation is for the 2D array to be a surface enclosing the region of interest and for the way it itself mechanically interferes with the sound to be predictable. If you're a bit careful with where you send the sound then perhaps the top/bottom exits wouldn't matter too much.
