> You might lose headroom
Pretty much my first point… At the same time that same DSP can make a pretty mediocre speaker that can reproduce those frequencies do so in phase at the listening position so once again the point is moot, effectively add a cheap sub.
There is no time where you cannot get results from mediocre transducers given the right processing.
I’m not arguing you should, but in 2025 if a speaker sounds bad it is entirely because processing was skimped on.
