When stereo came in, corner horns went away.

It wasn't a horn, it was a bass-reflex.

There's a lot less benefit in putting a bass-reflex design in a
corner, but you do still get that edge effect and the matter of
consistency.

Ime it is about the same 8 dB and they are worth having because the boost
from a corner is the smoothest available, also it fits a traditional tone
control very well and it is easy to get some degree of perceived
linearisation. With my current 4 way it is just a matter of overall bass
unit(s) drive level to get a reasonable tonal balance.
