How do manufacturers ensure a high degree of sonic consistency

same make and model? *Is* there a high degree of sonic consistency between two seemingly identical studio monitors/playback systems?

If you take as an example the LS3/5A BBC monitor speaker, the B110
bass drivers were selected to have a resonance frequency within 5Hz
for a matched pair. The internal resonance of the cabinet will pull
the speakers into line from that tolerance.

My (self-built, complete with auto-transformer) LS3-5As are lined,
instead of with bitumous sheet, lead !

Have checked the Fs of the drivers though, over the last 30 years ...
