Only a few years ago, I had the same opinion … but I was wrong.
There are some situations where you actually can reduce modal decay using DSP correction, especially if lower order axial modes:
How to tame a resonance at 22hz
In this example, we deliberately choose to ignore the first axial mode (in terms of treatment) and focus on higher order modes (that where more problematic) and then managed to fix the 1,0,0 mode with a filter that matched the Q and gain of the mode.
Having said that; I would naturally still opt for as much treatment as possible before reaching for that DSP …
I´m not a big fan of multi sub systems either (if “multi” means more than two). The best sounding systems I´ve heard has always consisted of two subs in the front (below the mains, carefully integrated using DSP) in a well-treated room.
